PLC Splitter Applications in FTTH Network

by www.fiber-mart.com

TTH mainly uses PON network technology, which requires a large number of low-cost optical splitters and other optical passive. Optical splitter device is an integral part of FTTH and with the promotion of FTTH, there would be a great market demand. The traditional preparation of optical splitter technology is fiber fused biconical taper (FBT) technology. Its characteristics are mature and simple technology. The disadvantage is that the assigned ones too large, and the device size is too large, which caused the decrease in yield and the rising cost of single channel, shunt reactive stars uniformity will deteriorate. FBT technology based fiber optic splitter preparation techniques have been unable to adapt to the market demand.
 
 
PLC splitter or planar lightwave circuit splitter is a passive component that has the special waveguide made of planar silica, quartz or other materials. It is employed to split a strand of optical signal into two or more strands. PLC splitter also has lots of split ratios, and the most common ones are 1:8, 1:16, 1:32, 1:64, 2:8, 2:16, 2:32 and 2:64. There are many types of PLC splitters to meet with different needs in OLT and ONT connection and splitting of optical signals over FTTH passive optical networks. There are seven major package types of PLC splitters according to different applications, i.e. bare fiber splitter, module splitter, rack-mount splitter, Mini Type splitter, Tray splitter and LGX splitter.
 
Bare fiber optical splitter
ABS splitters
Mini Type fiber splitter
Tray splitter
Rack-mount splitter
LGX splitters
PLC splitter in mini plug-in type
 
Applications
 
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.
 
Mini Type PLC Splitter
 
Mini Type 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. Mini PLC splitter is mainly used for different connections over distribution boxes or network cabinets.
 
ABS BOX TYPE PLC Splitter
 
ABS Box 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.
 
Tray Type PLC Splitter
 
Tray type PLC splitter can be regarded the fiber Tray which contains PLC fiber splitter inside a tray. 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.
 
 
 
Tray type PLC splitter
 
 
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
 
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.
 
Above these types of PLC splitters are typically installed to serve for PON and FTTH networks. 1xN and 2xN are the common splitter for specific applications. You can choose the correct one according to you projects and if any more questions pls feel free to contact us for any technical problem.
