Description

CWDM SFP transceiver for Fibre Channel providing 1/2/4 Gbps over single‑mode fiber. The 1530 nm channel (green) supports long‑distance SAN links and multi‑wavelength aggregation through passive CWDM MUX/DEMUX, with full DOM/DDM visibility for diagnostics. Suited to scalable, high‑density wavelength deployments in FC fabrics.

Features

- 1/2/4G Fibre Channel over single‑mode fiber
- 1530 nm CWDM channel ideal for multi‑wavelength deployments
- Extended reach up to 80 km
- Hot‑swappable SFP with low power draw
- Integrated digital diagnostics (DOM/DDM)
- Standards‑based LC duplex interface

Technical Specifications

FAQs

Q: Is it compatible with 1, 2, and 4 Gbps FC?
A: Yes, it supports 1/2/4 Gbps Fibre Channel line rates.

Q: What fiber and connector does it require?
A: Single‑mode fiber (9/125 µm) with LC duplex connectors.

Q: Can I reach 80 km?
A: Up to 80 km is supported when the end‑to‑end optical budget accommodates fiber and component losses.

Q: Is a CWDM MUX mandatory?
A: No. It’s optional; required only to multiplex multiple wavelengths on the same fiber pair.

Q: Does it include DOM/DDM?
A: Yes, for monitoring TX/RX power, temperature, and voltage.

Q: What does the green color denote?
A: Green indicates the 1530 nm CWDM channel for straightforward wavelength identification.
