Indispensable Solution for FTTx Applications - Fiber Termination Box

FTTx network architecture is now widely applied to telecommunications for long distance transmission. When using the fiber optic pigtails in FTTx network, it is very essential to protect the fiber terminations since fiber joints are fragile and easily contaminated by outside pollution. In response to the problem, an equipment named fiber termination box is created to house the fiber terminations in a safer place. There are also various types of fiber termination box (FTB) solutions for different applications. This article will provide the some detailed information about them to help you select the right device for your project.

Features of Fiber Termination Box
Fiber termination box provides an simple and clear way to manage the incoming and outcoming cables. Fiber bending radius is securely protected inside the box, thus signal integrity is also guaranteed. Since there is enough work room for fiber splicing and adapter patching, it is more flexible for technicians to use this device during work. Fiber termination box is a compact device offering a convenient access for installation, maintenance and subsequent termination. Fiber counts can be varied to satisfy the project requirements. When installed for different occasions, fiber termination box is also designed with different structures.

Classifications of Fiber Termination Box
Four common types of fiber termination boxes are widely used in FTTx networks, here will introduce them one by one. Hope you can find the most suitable type for your application.

Wall Mount Fiber Termination Box
From its name, we can know that this type of fiber termination box is wall-mountable for installation. The box consists of a front door and a side door. Both adapters and splice trays can be installed inside the box. It is typically used for applications like building entrance terminals, pre-connectorized cables, cross-connects, field connector installations, telephone closets, pigtail splicing, CATV, and computer rooms.

Fiber Termination Box Fiber Capacity
The fiber capacity of fiber termination box is often varied from 2 fibers to 192 fibers. Rack mount fiber termination box is usually available with the maximum fiber capacity of 192 fibers. Fiber splice trays can be stacked on top to increase fiber capacity. Therefore, fiber termination box is also a good solution for high-density applications when multiple fibers need to be well protected.

Conclusion
In summary, fiber termination box is an indispensable solution for FTTx network. Protecting and managing fiber splices and fiber splitters becomes much more efficient and flexible. In addition, choosing the right type of fiber termination box will also benefit the project deployment.

Have You Used Fiber Optic Wall Plate for FTTx Applications?

Did you notice the square object with jacks installed on the wall before? It is often called as wall plate. There is a variety of wall plates used in everyday life. Almost every room will have one to enable convenient cable deployment inside buildings and houses. As for FTTx applications, fiber optic wall plate is an indispensable component to keep fiber optic link away from dust and damage. This article will mainly give some details about fiber optic wall plate.

What Is Wall Plate?
First, let’s get to know more about the basics of wall plate. Wall plate, also called as wall outlet, workstation outlet or station outlet, is a flat plastic or metal plate that usually mounts in or on a wall (sometimes may be mounted in floors or ceilings). A wall plate has one or more jacks. A jack refers to the connector outlet employed for physical and electrical connection to the network cabling system. According to different networks, wall plates is divided into two types as fiber optic wall plates and copper wall plates. Since optical network has been leading the world trend, today we will get to know more about fiber optic wall plates.

Types of Fiber Optic Wall Plates
Fiber optic wall plate is designed to establish the connection between two fibers. Based on different adapters, fibers, port counts and port orientations, fiber optic wall plates have many classifications.

Classified by Adapter
There are typically four types of fiber optic connectors used in optical network, therefore the fiber optic adapters installed on the fiber optic wall plates are also different. LC, SC, FC and ST adapters are the common types. When you need to find a matching fiber optic wall plate, just check your fiber connector to see if it is the same type as the wall plate.

Classified by Port Count
As for port count of the fiber optic wall plate, a typical wall plate holds up to four ports. For individual homes, sing-port type is mostly used for FTTH network. But for the office buildings, multi-port type is required for FTTD applications. In addition, if other ports are aimed for different applications, the ports can be made as hybrid ports with mixed types of adapters.

Classified by Port Orientation
Port orientation is another way to divide fiber optic wall plates. Using the right orientations can provide fiber links better protection under different environment. Three common types of port orientations are straight, box-shaped and angled.

Classified by Fiber
Fiber optic cables are made of different types of fibers. In order to satisfy the demands for all kinds of fiber cable deployment, fiber optic wall plates are also distinguished by single-mode fibers of OS2, and multimode fibers of OM1, OM2, OM3 and OM4. Moreover, single-mode fiber optic wall plate is used for most FTTx projects.

How to Install Wall Plate?
As a reference, here are the recommended steps for installing box-shaped wall plates on the wall:
  • Step 1, determine the location of the new cabling wall plate. Use a pencil to mark a line indicating the location for the top of the wall plate.
  • Step 2, use the hole template to trace the outline of the hole to be cut onto the wall with a pencil. Keep the top of the hole aligned with the mark made in step 1.
  • Step 3, follow the lines and use a drywall keyhole saw to cut out a hole.
  • Step 4, insert the wall plate into the hole. If it won’t fit in, trim the sides of the hole with a razor blade or utility knife.
  • Step 5, secure the wall plate by screwing the box to the drywall or by using the friction tabs.
Conclusion
Fiber optic wall plate is an important part for FTTx applications. Selecting the right one from so many types of wall plates is also a task. All the aspects for your project should be taken into consideration. FS.COM is a place where you can find different types of fiber optic wall plates.

Building MDU Network into Brownfield and Greenfield

Multi-dwelling unit (MDU), namely multi-family residential, are the structures of housing where there are more than one living unit per location. MDU classification of housing has been considered as an important growth opportunity for communication services providers according to the population density and economics of scale. Generally speaking, there are two applications for MDU FTTx network deployments as “greenfield” and “brownfield”. This post will introduce the basic information about MDU and its network building applications.

Three Types of MDUs
In North America, MDUs can be classified into three construction versions of high-rise MDU, mid-rise MDU and low-rise MDU. Here will explain them one by one.

High-Rise MDU
This type of MDU refers to the large multi-story building like condo or apartment with more than ten floors and 128 living units using the internal residential entry. High-rise MDU is typically designed as vertical living style and planned for cabling access to the different stories and sections of the building thereby making sure that the FTTP network functions efficiently and reliably over high levels.

Mid-Rise MDU
Mid-rise (medium-rise) MDU is the leased or owned condo or apartment with up to 10 stories including 12 to 128 living units using the internal residential entry. For new mid-rise MDU, its fiber deployment is similar to the high-rise buildings. However, many old mid-rise MDUs are built as walk-ups and without provisions for new cabling networks. It is a challenge for these mid-rise residential buildings to find space for structured cabling.

Low-Rise MDU
Low-rise MDU is usually known as condo, townhouse or apartment constructed in garden style or horizontal style. There is only up to 3 floors or stories and 12 living units inside the low-rise MDU with external residential entry. The difficulty level for cable deployment also depends on whether the building is newly constructed.

Brownfield and Greenfield Applications
As mentioned above, the oldness and newness of residential buildings will affect the difficulty degree of cable installations. These two types of architectures are also the basic applications for building MDU network. Greenfield means the newly-built housing communities consisting of many separate living units typically joined together in one or several buildings. However, brownfield refers to the MDU that already exists in a typical urban area.

In a Brownfield application, a service provider must deliver fiber into the customer’s premises quickly, efficiently and securely. The ability to connect fibers as they are needed for new subscribers is best served using a simple “plug and play” approach. Thus, the splice storage should provide a demarcation point, such as a fiber demarcation box, equipped with industry standard connectors.

As for greenfield application, a network operator could ideally place the fiber to every living unit during initial construction. Fiber from every unit may then be run back to central closet and spliced as required inside a closure. A box such as the fiber splice box is an optimal and low cost solution.

Fiber Connectivity Methods
In MDU network applications, service providers can use factory-terminated patch cords or fusion-spliced pigtails to connect fibers. Patch cords are efficient connectivity methods because no tools or splices are required in the field to make the termination. Their simple plug and play installation also minimizes the required skills for setting up the connection, which reduces installation time and labor costs.

Fusion-spliced pigtails can alleviate the issues of cable management for massive patch cords and cable waste for long patch cords. However, the fusion splice machine is expensive and specialized training is required. The fusion splicer also requires electrical power in places like MDU hallways where power outlets aren’t readily available.

Conclusion
The building of FTTx network in MDUs has become more and more popular around the world. Project installer should make proper connectivity plan according to different structures of MDUs. The complexity of deployment will also depends on whether the MDU is built in greenfield or brownfield. A successful network deployment in MDU is measured in many ways.

What is FTTx Network?


FTTx

Since the customers have demanded for a more intensive bandwidth, the telecommunication carriers must seek to offer a matured network convergence and enable the revolution of consumer media device interaction. Hence, the emergence of FTTx technology is significant for people all over the world. FTTx, also called as fiber to the x, is a collective term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. With different network destinations, FTTx can be categorized into several terminologies, such as FTTH, FTTN, FTTC, FTTB, FTTP, etc. The following parts will introduce the above terms at length.


FTTH
FTTx is commonly associated with residential FTTH (fiber to the home) services, and FTTH is certainly one of the fastest growing applications worldwide. In an FTTH deployment, optical cabling terminates at the boundary of the living space so as to reach the individual home and business office where families and officers can both utilize the network in an easier way.

FTTN
In a FTTN (fiber to the node) deployment, the optical fiber terminates in a cabinet which may be as much as a few miles from the customer premises. And the final connection from street cabinet to customer premises usually uses copper. FTTN is often an interim step toward full FTTH and is typically used to deliver advanced triple-play telecommunications services.

FTTC
In a FTTC (fiber to the curb) deployment, optical cabling usually terminates within 300 yards of the customer premises. Fiber cables are installed or utilized along the roadside from the central office to home or office. Using the FTTC technique, the last connection between the curb and home or office can use the coaxial cable. It replaces the old telephone service and enables the different communication services through a single line.

FTTB
In a FTTB (fiber to the building) deployment, optical cabling terminates at the buildings. Unlike FTTH which runs the fiber inside the subscriber’s apartment unit, FTTB only reaches the apartment building’s electrical room. The signal is conveyed to the final distance using any non-optical means, including twisted pair, coaxial cable, wireless, or power line communication. FTTB applies the dedicated access, thus the client can conveniently enjoy the 24-hour high speed Internet by installing a network card on the computer.

FTTP
FTTP (fiber to the premise) is a North American term used to include both FTTH and FTTB deployments. Optical fiber is used for an optical distribution network from the central office all the way to the premises occupied by the subscriber. Since the optical fiber cable can provide a higher bandwidth than copper cable over the last kilometer, operators usually use FTTP to provide voice, video and data services.

FTTx Network Applications
With its high bandwidth potential, FTTx has been closely coupled with triple play of voice, video and data services. And the world has now evolved beyond triple play to a converged multi-play services environment with a high bandwidth requirement. Applications like IPTV, VOIP, RF video, interactive online gaming, security, Internet web hosting, traditional Internet and even smart grid or smart home are widely used in FTTx network.

Conclusion
FTTx technology plays an important part in providing higher bandwidth for global networks. According to different network architectures, FTTx is divided into FTTH, FTTN, FTTC, FTTB, FTTP, etc. FS.COM provides FTTx solutions and tutorials for your project, please visit FS.COM for more information.
