Enet
127509‑B21‑ENC – OEM-Compatible FC Optical LW‑GBIC | Fibre Channel Long‑Wave Module, SC Connector
The Enet 127509‑B21‑ENC is an OEM-compatible Fibre Channel (FC) long-wave GBIC module designed to deliver dependable 1 Gbps optical connectivity over distances up to 2 km. With an SC duplex connector, this unit supports a long-wave (LW) 1310 nm laser and is fully compliant with MSA and IEEE standards. Engineered to match the original Compaq/HP 127509-B21 specification, Enet solution offers plug-and-play compatibility at a budget-friendly price, making it ideal for enterprise storage networks, SAN fabric connectivity, and legacy switch environments where reliability and interoperability are paramount.
Features
The 127509‑B21‑ENC is built to match the performance and form factor of the original Enet (or Compaq/HP) GBIC part, offering 100% compatibility through factory programming, serialization, and rigorous testing for latency, frame loss, transmit/receive power, and error rates. The SC duplex connector interface simplifies deployment across Fibre Channel fabrics, SAN arrays, and legacy storage switches supporting 1 Gbps links. The transceiver supports both single-mode and multimode fiber, although optimized for single-mode up to 2 km at 1310 nm.
Advanced Options
Enet certifies full interoperability with MSA-compliant switching and routing platforms, and the optic is also RoHS certified, ensuring environmental compliance. It’s programmed to avoid vendor lockout, offering seamless integration with the host firmware on HP/Compaq and other OEM systems
