Comprehensive Guide to Choosing the Right  PLC Splitter for Your Fiber Network

What is a PLC Splitter?

A PLC splitter, or Planar Lightwave Circuit splitter, is a fundamental passive component in fiber optic networks. It splits a single optical signal evenly across multiple output ports, facilitating efficient signal transmission and distribution.

PLC splitters are widely used across various fiber optic communication systems, including Fiber to the Home (FTTH), metropolitan area networks, and data centers. By maximizing fiber utilization, they enable multi-user access and support flexible service deployment. Selecting the correct PLC splitter is crucial for the reliability and performance of any fiber network.

In-Depth Guide to Selecting the Right PLC Splitter for Your Network

With increasingly complex network environments, choosing the appropriate PLC splitter—considering the range of package types and installation styles—can significantly affect network efficiency. Here’s a detailed look at different types of PLC splitters and their applications to help you make the best choice.

1. Bare Fiber PLC Splitter

The bare fiber PLC splitter is one of the simplest and most commonly used types, particularly in FTTx applications. As its name suggests, this splitter has exposed optical fibers that need protective sleeves for safety during installation. Without connectors on either end, bare fiber PLC splitters require fiber splicing, which allows customization to fit specific applications. Compact and space-saving, they can be placed in a fiber optic terminal box, where they are securely protected and organized for FTTx network use. Key features of bare fiber PLC splitters include:

• Design: Exposed fiber with no pre-installed connectors, allowing custom splicing.
• Application: Ideal for FTTx, PON, and LAN networks with space constraints.
• Cost-Effectiveness: A budget-friendly option for various network environments.

2. Blockless PLC Splitter

The blockless PLC splitter, also known as a mini-module splitter, closely resembles the bare fiber splitter but with enhanced fiber protection. It typically includes connectors on both ends, which simplifies installation. Blockless PLC splitters can also be mounted within an  fiber optic termination box, ensuring more secure fiber management and protection. Key attributes include:

• Protection: Greater fiber protection than bare fiber splitters.
• Installation Convenience: Pre-installed connectors reduce setup time.
• Application: Suitable for scenarios needing added fiber protection, such as in distribution boxes or network cabinets.

3. ABS Module PLC Splitter

ABS PLC splitters use a durable plastic enclosure made from ABS (Acrylonitrile Butadiene Styrene) material, offering excellent impact resistance and thermal stability. This enclosure effectively protects internal optical components, ensuring reliability under diverse environmental conditions. ABS modules are lightweight, making them easy to install in fiber distribution boxes and cabinets. Important features include:

• Material: ABS plastic for robust, temperature-resistant protection.
• Flexibility: Suitable for various installations, including PON and FTTH.
• Application: Commonly used in outdoor fiber distribution for stable performance in different settings.

4. Cassette PLC Splitter

Cassette PLC splitters have two types : LGX Cassette PLC Splitters and FHD Cassette PLC Splitters. They are housed in a metal module that can be used independently or mounted in a standard 1U rack unit for centralized management. The pluggable module design allows quick replacement or addition of splitters as needed, making maintenance easy without affecting other equipment. Key features of cassette PLC splitters include:

• Encapsulation: Metal case offers durability and modularity.
• Plug-and-Play: Easily added or replaced to meet network needs.
• Application: Ideal for flexible applications and modular setups, allowing rapid adjustments.

5. 1U Rack Mount PLC Splitter

Designed specifically for rack installations, the 1U Rack Mount PLC Splitter  provides up to 64 ports within a 1U, 19-inch rack. This configuration maximizes space efficiency, making it a preferred option in high-density environments like data centers and server rooms. Key features of rack-mounted PLC splitters include:

• High Density: Supports up to 64 ports for efficient space use.
• Rack Compatibility: Fits standard 1U racks, perfect for structured cabling.
• Application: Suitable for high-density installations, such as EPON, GPON, and FTTH networks.
