Description

High-density CWDM 8G Fibre Channel transceiver engineered for long-reach SAN links over single-mode fiber. Operating at 1590 nm with LC duplex, it supports 2/4/8G FC and provides DOM for live optics monitoring—ideal for passive CWDM mux/demux networks.

Features

- Supports 2/4/8G Fibre Channel for broad SAN interoperability
- Utilizes the 1590 nm CWDM channel for efficient wavelength planning
- Long-reach up to 40 km across single-mode fiber
- DDM/DOM for proactive optical monitoring
- Hot-swappable SFP+ for simplified maintenance
- Low power consumption for dense port counts

FAQs

Q: Will this work in a 2G or 4G FC environment?
A: Yes. It supports 2/4/8G FC and will operate at the port’s configured speed.

Q: Is it compatible with passive CWDM systems?
A: Yes. Use the 1590 nm channel on the mux/demux and validate optical budget.

Q: What connector and fiber does it require?
A: LC duplex connectors on single-mode OS2 fiber.

Q: Does it provide digital diagnostics?
A: Yes. DOM/DDM is supported for monitoring optical metrics.

Q: What is the maximum link distance?
A: Up to 40 km on SMF, depending on path loss and components in the link.
