Overview

Huawei CFP-1310nm-40GBASE-ER4 Overview

Huawei CFP-1310nm-40GBASE-ER4 is a carrier-grade CFP transceiver designed for long-haul 40Gb/s single-mode fiber links. Operating over a 1271~1331nm wavelength range, it delivers a 41.25Gb/s data rate with 40km transmission distance for metro and data center interconnect. The module uses an angled LC connector and supports SMF, making it ideal for telecom operators and large enterprises needing high-bandwidth, low-latency backbone connectivity.

Product Applications Scenarios

Data Center

High-density 40Gb/s CFP uplinks simplify spine-leaf interconnects, extending resilient data center fabrics up to 40km while reducing the need for additional DWDM gear.

Service Providers

Carrier networks use 40km SMF reach and stable 1271~1331nm optics to aggregate metro rings, cutting backbone interface count and simplifying optical layer planning.

Enterprise Network

Large campuses deploy 40Gb/s ER4 links for core-to-core connectivity, extending Layer 3 domains across sites without complex amplification or regeneration stages.
