How to Choose Fiber Optical Splitter

Fiber optic splitters play an increasingly significant role in many of today’s optical network topologies. They provide capabilities that help users maximize the functionality of optical network circuits from FTTx systems to traditional optical networks. And usually they are placed in the central office or in one of the distribution points (outdoor or indoor).

What Is Fiber Optic Splitter?

A fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. These beams may or may not have the same optical power as the original beam, based on the configuration of the splitter. By means of construction, the outputs of an optical splitter can have varying degrees of throughput, which is highly beneficial when designing optical networks, whether the optical splitter is used for network monitoring or for a loss budget in passive optical network (PON) architecture. Generally, there are two types of fiber optic splitters, which are FBT splitters and PLC splitters.

FBT Splitter

FBT splitter is one of the most common splitters, which is widely accepted and used in passive networks. FBT splitter is designed for power splitting and tapping in telecommunication equipment, CATV network, and test equipment.

PLC Splitter

PLC splitter is a hot research at home and abroad today, with a good prospect of application, which is used to distribute or combine optical signals. It is based on planar light wave circuit technology and provides a low cost light distribution solution with small form factor and high reliability.

Applications for PLC Splitter

Bare Fiber PLC Splitter

Bare fiber PLC splitter has no connector at the bare fiber ends. It can be spliced with other optical fibers in the pigtail cassette, test instrument and WDM system, which minimizes the space occupation. It is commonly used for FTTH, PON, LAN, CATV, test equipment and other applications.

Blockless PLC Splitter

Likewise, blockless PLC splitter has a similar appearance as bare PLC splitter. But it has a more compact stainless tube package which provides stronger fiber protection, and its fiber ends are all terminated with fiber optic connectors. Connectors are commonly available with SC, LC, FC and ST types. Thus, there is no need for fiber splicing during installation. Blockless PLC splitter is mainly used for different connections over distribution boxes or network cabinets.

ABS PLC Splitter

ABS PLC splitter has a plastic ABS box to protect the PLC splitter to adapt to different installation environments and requirements. Common splitter modules are 1×4, 1×8, 1×16, 1×32, 1×64, 2×4, 2×8, 2×16, 2×32. It is widely used with outdoor fiber distribution box for PON, FTTH, FTTX, PON, GOPN networks.

Fanout PLC Splitter

PLC splitter with fan-out is mainly used for 0.9mm optical fiber where the ribbon fiber can convert to 0.9mm optical fiber through fan-out. 1×2, 1×4, 1×8, 1×16, 1×32, 1×64, 2×2, 2×4, 2×8, 2×16, 2×32, 2×64 fanout types are all available with PLC splitters. Fiber adapters can also be used for the input and output ends of this kind of splitters to directly meet the demand on smaller size of splitters.

Tray Type PLC Splitter

Tray type PLC splitter can be regarded the fiber enclosure which contains PLC fiber splitter inside a enclosure. It is often directly installed in optical fiber distribution box or optical distribution frame. FC, SC, ST & LC connectors are selective for termination. Tray type PLC splitter is an ideal solution for splitting at the places that are near OLT or ONU.

Rack-mount PLC Splitter

Rack-mount PLC splitter can be used for both indoor and outdoor applications in FTTx projects, CATV or data communication centers. It uses the 19-inch rack unit standard to contain the PLC splitter inside a rack unit.

LGX PLC Splitter

LGX PLC splitter or LGX box PLC splitter has a strong metal box to house the PLC splitters. It can be used alone or be easily installed in standard fiber patch panel or fiber enclosure. The standard LGX mental box housing provides a plug-and-play method for integration in the network, which eliminates any risk during installation. No filed splicing or skilled personnel is required during deployment.

Mini Plug-in Type PLC Splitter

Similar to the LGX PLC splitter, mini plug-in PLC type splitter is its small version with a compact design. It is usually installed in the wall mount FTTH box for fiber optic signal distribution. Using the mini plug-in PLC type splitter saves time and space but still provides reliable protection for the fiber optic splitter.
