PLC Splitter

A PLC splitter uses planar waveguide technology to divide one or two optical signals into multiple outputs with a specific split ratio, such as 1×4, 1×8, 1×16, or 1×32. It ensures stable performance across a wide wavelength range and is suitable for both indoor and outdoor fiber optic distribution applications.

1. Structure & Design

• Working Principle: Based on silica optical waveguide circuit technology, enabling precise signal splitting with minimal loss.

• Splitter Configurations:

  • 1xN: 1 input, multiple outputs (e.g., 1×4, 1×8, 1×16, 1×32, 1×64)

  • 2xN: 2 inputs, multiple outputs (e.g., 2×4, 2×8, 2×16)

• Packaging Types:

  • Bare Fiber Type – compact, for integration in fiber management boxes

  • Steel Tube Type – protective housing for harsh environments

  • ABS Box Type – standardized casing for easy installation

  • LGX Module Type – plug-in module for rack mount use

  • Mini Module Type – small footprint, ideal for limited space applications

  • 1U Rack Mount Type – high-density installation in network cabinets

• Connector Options: SC, LC, FC, ST; UPC or APC polish

• Operating Wavelength: 1260–1650 nm

• Uniformity: ≤1.0 dB (varies by split ratio)

• Operating Temperature: -40°C to +85°C

2. Applications

• FTTH (Fiber to the Home) and FTTx networks

• Passive Optical Networks (PON: EPON, GPON)

• CATV (Cable Television) systems

• Optical signal monitoring and testing

• LAN/WAN and Metro area networks

• Centralized and distributed optical signal distribution

3. Advantages

• Uniform optical signal distribution across all output ports

• Low insertion loss and high return loss

• Excellent environmental and mechanical stability

• Multiple package styles for flexible installation

• Available in wide range of split ratios (1×2 to 1×64, 2×2 to 2×64)

• High reliability and long service life

• Factory-tested for optical performance and quality compliance (GR-1209/1221, Telcordia, RoHS)

4. FAQs

• Q1: What’s the difference between PLC and FBT splitters?
  PLC splitters use waveguide circuits and offer better performance for higher split ratios, while FBT splitters are more suitable for lower count and are made by fusing optical fibers.
• Q2: Can I use PLC splitters outdoors?
  Yes. We offer ruggedized types (e.g., steel tube, waterproof closure) suitable for outdoor deployments.
• Q3: How do I choose the right split ratio?
  It depends on the number of users/endpoints you need to serve. Common ratios include 1×8, 1×16, and 1×32 for FTTH networks.
• Q4: Do splitters affect signal strength?
  Yes, splitters divide the signal, so insertion loss increases with higher split ratios—but our PLC splitters maintain uniformity and low loss across all ports.
• Q5: Can I get pre-terminated splitters with connectors?
  Absolutely. We provide custom pre-terminated splitters with SC/LC/FC/ST connectors, UPC/APC polish, and jacketed or bare fiber options.
