H3C SFP-GE-LH40-SM1490-BIDI 1G BIDI SFP TX1490/RX1310 40km LC Single-Mode Optical Transceiver Full Datasheet

Basic Parameter Table

Core Product Features

1. Original H3C single-fiber bidirectional gigabit BiDi SFP optical module, paired matching model of SFP-GE-LH40-SM1310-BIDI, fully compatible with all H3C gigabit switches, firewalls and routers with SFP slots.
2. Complies with Gigabit BiDi SFP MSA standard, single simplex fiber bidirectional transmission: transmit 1490nm, receive 1310nm, must pair with TX1310/RX1490 BiDi module for end-to-end communication, stable 40km transmission over G.652 single-mode fiber.
3. Built-in DOM digital optical monitoring circuit, real-time monitoring of transmit/receive optical power, supply voltage, internal temperature and laser bias current for remote link fault diagnosis.
4. Standard hot-swappable plug-and-play SFP design, no equipment power-off required during replacement, convenient for enterprise and operator weak current room maintenance.
5. Compact metal sealed housing with optimized heat dissipation, strong anti-electromagnetic interference performance, suitable for core cabinet and outdoor communication equipment deployment.
6. Fiber-saving single-fiber bidirectional solution, halves single-mode fiber core consumption, perfect for cross-building network reconstruction with insufficient fiber resources.

Typical Application Scenarios

1. Enterprise multi-branch cross-building gigabit uplink within 40km single-mode fiber coverage, fiber shortage renovation project.
2. Operator small enterprise private line, FTTO office gigabit fiber access.
3. Long-distance industrial monitoring, park security gigabit fiber transmission.
4. Not applicable: dual-fiber symmetric optical modules, multi-mode short-reach transmission, 10G/25G high-speed Ethernet modules.
