Description

CWDM SFP transceiver for 1 Gigabit Ethernet and 2 Gbps Fibre Channel using the 1530 nm ITU CWDM channel. LC duplex, hot-swappable SFP MSA with digital diagnostics (DDM/DOM) for monitoring. Designed for long-distance single-mode links and high-density CWDM multiplexing. Actual reach up to 80 km depends on link budget and fiber plant conditions.

Features

- 1530 nm CWDM channel for dense wavelength deployments
- Up to 80 km reach over single-mode fiber
- Supports both 1GbE and 2G Fibre Channel
- Hot-swappable SFP with LC duplex connector
- DOM/DDM support for proactive monitoring
- Standards-based CWDM (ITU-T G.694.2) interoperability

FAQs

Q: Is this SFP compatible with standard 1G SFP switch ports?
A: Yes, if the port supports 1G optics and the platform accepts CWDM SFPs.

Q: What type of fiber is required?
A: 9/125 µm single-mode fiber with LC connectors.

Q: Does it support 2 Gbps Fibre Channel?
A: Yes, it is suitable for 2G FC links on supported SAN switches.

Q: Is a CWDM Mux/Demux mandatory?
A: No, it is optional unless you need to combine multiple wavelengths on the same fiber pair.

Q: Is this a BiDi optic?
A: No, it uses two fibers (LC duplex) for transmit and receive.

Q: Does it provide DOM readings?
A: Yes, it supports SFF-8472 DDM/DOM for optical power and temperature monitoring.

Q: What is the maximum reach?
A: Up to 80 km, depending on fiber attenuation, splices, and overall link budget.
