Description

CWDM SFP for Fibre Channel SANs delivering 1/2/4 Gbps line rates on single‑mode fiber. The 1510 nm channel (blue) enables long‑reach links and efficient wavelength multiplexing over passive CWDM systems while providing DOM/DDM for real‑time optics monitoring. Ideal for extending FC fabrics or aggregating multiple wavelengths over a single fiber pair.

Features

- 1/2/4G Fibre Channel performance for SAN extension
- 1510 nm CWDM channel for dense wavelength multiplexing
- Long‑reach optics up to 80 km on SMF
- Hot‑swappable SFP with low power consumption
- Digital diagnostics (DOM/DDM) for proactive monitoring
- LC duplex interface for standard SMF cabling

Technical Specifications

FAQs

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

Q: Is this transceiver for single‑mode or multimode fiber?
A: Single‑mode fiber (9/125 µm) only.

Q: What is the maximum distance?
A: Up to 80 km, subject to fiber attenuation, splice/connector losses, and CWDM MUX/DEMUX insertion loss.

Q: Can I use it point‑to‑point without a CWDM MUX?
A: Yes. A CWDM MUX/DEMUX is only required when multiplexing multiple wavelengths on the same fiber pair.

Q: Does it provide DOM/DDM?
A: Yes, it supports digital optical monitoring for parameters such as TX/RX power and temperature.

Q: What connector type does it use?
A: LC duplex.

Q: What does the blue color indicate?
A: Blue denotes the 1510 nm CWDM channel for easy identification during wavelength planning.
