Description
A PLC splitter is a passive optical device for integrated waveguide optical power distribution based on a quartz substrate, manufactured by means of semiconductor lithography, etching, development and other technologies. Its internal optical waveguide array is located on the upper surface of the chip, and the splitting function is highly integrated into the chip. It can achieve a splitting ratio of 1:N or 2:N (where N is 2. 4. 8. 16. 32. 64. 128. etc.), uniformly distributing one or two optical signals into multiple outputs according to a specific ratio. Its internal optical structure is precisely designed to ensure low loss and high stability of optical signals during splitting or combining processes. It is widely used in fiber optic communication networks, especially in scenarios such as FTTH and 5G base station fronthaul, to realize efficient distribution and convergence of signals.
Feature
● Low insertion loss:Minimal signal power loss
● High uniformity:Balanced output optical power
● Strong directivity:Suppresses reverse signal interference
● Wide wavelength compatibility: Adapts to single-mode/multi-mode signals
● High reliability: Stable operation in complex environments
● Multiple splitting ratios:1:2~1:128 available
Application
● FTTH:ODN network OLT-ONU signal distribution
● 5G base station fronthaul:Signal splitting/combining for base station equipment
● CATV network: Stable signal distribution to user terminals
● Data centers: Signal distribution/convergence for servers and storage
● Fiber optic sensing: Light source signal splitting and feedback collection
● PLC Fiber Splitter Product Classification
PLC Fiber Splitter Product Classification
| Bare Fiber Type | | Only bare fibers are left at the ends of the product. It is often used in scenarios where disassembly is infrequent, such as inside cable connector boxes and fiber distribution panels. Its advantage lies in its small size, which can closely fit the internal space and reduce installation complexity. However, additional protection for the bare fibers is required to avoid mechanical damage. |
| Mini Type | | Mostly encapsulated in micro steel tubes, it comes in two versions: with and without connecting pigtails. The connectors include common types such as SC, LC, FC, and ST. This type can be easily installed in cable joint boxes, module boxes, and distribution boxes, making it suitable for small - scale wiring scenarios with strict space - occupancy requirements, such as local nodes in indoor integrated wiring. |
| Cassette Type |
| Installed and fixed in a cassette box, with interface types including SC/FC/LC, etc. It is mainly applied at corridor or outdoor splitting points in FTTH access methods. Common PLC splitters with specifications such as 1X4, 1X8, 1X16, 1X32, 2X8, 2X16, and 2X32 are often used as cassettes and installed in customer - specific chassis, especially corridor boxes, facilitating splitting operations in limited - space areas such as corridors. |
| LGX Type | | The optical splitter is encapsulated in a small metal box and can be installed in 19 - inch 1U/2U/3U frames. The input and output ends have a pigtail - type structure, which can be easily connected to ODF panel adapters. With its compact and mini - design and plug - and - play characteristics, it is suitable for fiber splitting boxes, ODF sub - frames, fiber terminal boxes, and cable distribution boxes, saving installation space and time, and having obvious advantages in fiber - wiring scenarios with limited space and high requirements for installation convenience. |
| Box Type | | Mostly encapsulated with ABS materials, it is the most widely used type among operators. Its compact packaging allows for extremely flexible deployment. It can be installed in 19 - inch standard racks, cable distribution boxes, or customer - specified equipment. It is often used at signal distribution nodes in fiber - to - the - home scenarios, effectively protecting the internal optical components and adapting to various installation environments. |
