H3C SFP-FE-LX-SM1310-D 155M FE LX ESFP 1310nm 15km Single-Mode Optical Transceiver Full Datasheet

Basic Parameter Table

Core Product Features

1. Original H3C 155M Fast Ethernet LX single-mode ESFP optical module, fully compatible with H3C old-generation FE switches, industrial security equipment and low-speed access routers.
2. Complies with 155M FE ESFP MSA standard, single 1310nm DFB laser, stable 15km 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 ESFP design, no equipment power-off required during module replacement, convenient for campus and industrial network O&M.
5. Compact metal sealed housing with optimized heat dissipation, strong anti-electromagnetic interference performance, suitable for weak current room and industrial cabinet deployment.
6. Low-cost medium-reach single-mode interconnection solution, widely used for campus old FE network reconstruction, industrial park low-speed remote access links.

Typical Application Scenarios

1. Campus legacy Fast Ethernet switch interconnection within 15km single-mode fiber coverage.
2. Industrial park, community security monitoring low-speed remote fiber transmission.
3. Small branch enterprise old network 155M remote access convergence.
4. Not applicable: multi-mode short-reach transmission, gigabit/10G high-speed Ethernet.
