Basic Parameter Table

Core Product Features

1. Original H3C enterprise-grade 1.25G long-reach single-mode SFP module, fully compatible with H3C S5130/S5560/S6520 series switches, firewalls and storage servers.
2. Complies with IEEE 802.3 1000BASE-EX & SFP MSA standard, adopts high-performance 1550nm DFB laser, stable 40km transmission over G.652 single-mode fiber, better anti-dispersion performance than 1310nm modules for long-distance links.
3. Built-in DOM digital optical monitoring function, real-time monitoring of Tx/Rx optical power, supply voltage, chip temperature and bias current for fast fault diagnosis.
4. Standard hot-swappable plug-and-play SFP design, no equipment power-off required during replacement, simplifies cross-regional enterprise network and remote monitoring system maintenance.
5. Compact metal housing with integrated heat dissipation, excellent anti-electromagnetic interference capability, suitable for outdoor weak current cabinets and central computer room deployment.
6. Cost-effective long-distance single-mode interconnection solution, widely used in cross-district enterprise headquarters & branch fiber backbone, remote HD video surveillance and rural broadband aggregation.

Typical Application Scenarios

1. Cross-district enterprise headquarters and branch office fiber interconnection within 40km single-mode fiber coverage.
2. Long-distance HD video surveillance, rural broadband access aggregation, industrial park cross-building gigabit fiber backbone links.
3. Not applicable for multi-mode fiber short-distance transmission and high-speed 10G/25G Ethernet scenarios.
