Introduction
PLC Splitter (Planar Lightwave Circuit Splitter) is one of the most important passive optical components in FTTH, FTTx, GPON, and XGS-PON networks. It enables a single optical signal to be distributed to multiple subscribers while maintaining stable optical performance.
Selecting the right PLC splitter is critical for network reliability, deployment efficiency, and future scalability. The appropriate splitter ratio, package type, and connector configuration can significantly reduce installation and maintenance costs while improving network performance.
In this guide, we explain how to choose the right PLC splitter for different network applications and deployment environments.
PLC splitter (Plane Lightwave Circuit Splitter) is an essential passive component in fibre optic networks, especially in FTTH and Quick ODN network structures. PLC splitter can maximize the use of optical fibre resources to support multi-user access and flexible deployment of various services. Therefore, choosing the right PLC splitter is directly related to the overall performance and reliability of the network.
What Is a PLC Splitter?
A PLC splitter is a passive optical device manufactured using planar lightwave circuit technology. It divides one optical input signal into multiple output signals with uniform power distribution.
Compared with traditional FBT splitters, PLC splitters offer:
- Wider operating wavelength range
- Better uniformity
- Lower insertion loss
- Higher reliability
- Support for high split ratios
PLC splitters are widely used in:
- FTTH Networks
- GPON Networks
- XGS-PON Networks
- CATV Systems
- Data Communication Networks
Key Factors When Selecting a PLC Splitter
Before selecting a PLC splitter, several factors should be considered.
Split Ratio
The split ratio determines how many subscribers can be connected.
Abalone Group offers 5 different types of PLC splitter packages, each designed to meet specific usage requirements and environments, providing you with a variety of flexible options:
| Split Ratio | Typical Application |
|---|---|
| 1×2 | Testing and monitoring |
| 1×4 | Small FTTH deployment |
| 1×8 | Residential FTTH network |
| 1×16 | Apartment buildings |
| 1×32 | GPON access network |
| 1×64 | Large FTTH deployment |
Connector Type
Common connector options include:
- SC/APC
- SC/UPC
- LC/APC
- LC/UPC
Installation Environment
The installation environment directly determines which package type should be selected.
Common PLC Splitter Package Types
Abalone offers five major PLC splitter package formats for different deployment environments.
PLC Splitter Selection by Application
Different network scenarios require different PLC splitter configurations.
| Application | Recommended PLC Splitter |
|---|---|
| FTTH Residential Network | 1×8 PLC Splitter |
| Apartment Building | 1×16 PLC Splitter |
