Description

Product Overview

The LL-SFP-10G-BX40 is a professional-grade 10G BiDi SFP+ Transceiver designed for medium-to-long-distance optical communication over a single strand of single mode fiber.

Unlike conventional duplex transceivers that require two fibers, the SFP-10G-BX40 uses bidirectional transmission technology to send and receive optical signals through one fiber using different wavelengths. This significantly reduces fiber deployment costs while maintaining stable 10Gbps Ethernet performance.

Powered by advanced 10G WDM SFP+ technology, the module provides an efficient solution for metro access networks, enterprise backbone infrastructure, campus interconnection, and carrier Ethernet applications where fiber efficiency and network reliability are essential.

Understanding Optical Loss for 40km Links

The LL-SFP-10G-BX40 is commonly deployed in metro and regional fiber networks where optical budget planning is important for maintaining reliable service.

Typical single mode fiber attenuation:

1310nm: approximately 0.35 dB/km
1550nm: approximately 0.25 dB/km

For a typical 40km deployment:

Fiber attenuation: 10–14 dB
Connector loss: 0.5–1.0 dB
Splice loss: 0.2–0.8 dB

The total link loss generally ranges between 12 and 16 dB.

This makes the SFP-10G-BX40 an ideal choice for metro Ethernet and enterprise backbone applications without requiring complex optical amplification systems.
