CSFP Optical Transceiver: Basics & Product Introduction

1. Introduction: What Is CSFP?
 

CSFP (Compact Small Form-factor Pluggable) is a compact optical transceiver designed to increase port density in telecommunications and access network equipment.
 

Compared with a conventional SFP, a CSFP module can support two independent optical channels within a similar compact form factor, depending on the implementation.
 

CSFP technology was developed primarily to address the growing demand for higher port density, lower equipment costs, and more efficient use of rack space in telecommunications networks.

2.How CSFP Works

A typical dual-channel CSFP module integrates two independent bidirectional optical transceiver channels.

Each channel can transmit and receive optical signals through a single fiber using different wavelengths.

For example:

1.Channel A: 1310 nm TX / 1490 nm RX.

2.Channel B: 1490 nm TX / 1310 nm RX.

The actual wavelength configuration depends on the product specification and application. Complementary wavelength versions are required at the opposite end of the link.
