H3C SFP-GE-LX-SM1310-D 1.25G Gigabit SFP Transceiver | 1310nm | 10km SMF | DDM

Product Overview

The H3C SFP-GE-LX-SM1310-D is a genuine H3C Gigabit SFP optical transceiver designed for reliable, long-distance fiber connectivity in enterprise networks. Operating at 1310nm over single-mode fiber up to 10km, it delivers stable 1.25Gbps performance for switch uplinks, campus backbone connections, and inter-building fiber links — all in a compact, hot-swappable SFP form factor.

With built-in Digital Diagnostic Monitoring (DDM/DOM), network administrators can monitor real-time optical parameters including TX/RX power, temperature, and voltage — keeping your infrastructure healthy and reducing unplanned downtime.
