Huawei SFP-GE-LX-SM1310 1000BASE-LX 1310nm Singlemode GE eSFP Optical Module (10 km, 02313URF)

Product Overview

The SFP-GE-LX-SM1310 (Huawei part number 02313URF) is an SFP (eSFP) optical module for 1.25 Gbit/s 1000BASE-LX Gigabit Ethernet links over singlemode fiber. It uses a 1310 nm center wavelength with an LC duplex connector and is documented by Huawei for a 10 km target distance on G.652 SMF, with Tx power of -9.0 to -3.0 dBm and receiver sensitivity of -20 dBm.

The module follows the enhanced eSFP practice of monitoring supply voltage, temperature, laser bias current and optical power, so link health can be polled from the host switch. Its 10 km singlemode budget covers the large majority of inter-building and metro-access spans without repeaters or amplification.

Typical applications include campus and metro-access links between Huawei switches and routers over leased or owned singlemode fiber, Point-to-Point GE connectivity between buildings up to 10 km apart, and uplinks from access switches to aggregation nodes.
