Description

Product Overview

The LL-SFP-10G-BX20 is a compact 10G BiDi SFP+ Transceiver designed for high-speed Ethernet transmission over a single strand of single mode fiber.

Unlike conventional duplex optical modules, the SFP-10G-BX20 uses bidirectional transmission technology to send and receive data on different wavelengths through one fiber. This approach significantly reduces fiber usage while maintaining full 10Gbps network performance.

By incorporating 10G WDM SFP+ technology, the module provides a cost-effective solution for enterprise access, industrial networks, and fiber broadband infrastructure where efficient fiber utilization is essential.

Understanding Optical Loss for 20km Links

The LL-SFP-10G-BX20 is optimized for medium-distance fiber deployments where stable optical performance is required.

Typical single mode fiber attenuation:

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

For a typical 20km deployment:

Fiber attenuation: 6–7 dB
Connector loss: 0.5–1.0 dB
Splice loss: 0.2–0.5 dB

The total link loss is generally between 7 and 9 dB, making the SFP-10G-BX20 suitable for enterprise access and regional fiber connections without requiring optical amplification.
