Description

Compact CWDM SFP for 1 Gigabit Ethernet and 2 Gbps Fibre Channel links using the 1510 nm channel. Hot-swappable SFP MSA design with LC duplex interface and digital diagnostics (DDM/DOM). Ideal for long-reach single-mode deployments and CWDM mux/demux systems to maximize fiber utilization. Link distance up to 80 km depends on span loss, splices, and optics on the far end.

Features

- Supports both 1GbE and 2G Fibre Channel on the 1510 nm CWDM channel
- Long-reach performance up to 80 km over SMF
- Hot-swappable SFP with LC duplex interface
- MSA-compliant with DDM/DOM for real-time monitoring
- Optimized for use with CWDM mux/demux to maximize fiber utilization
- Low power consumption and broad platform compatibility

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

FAQs

Q: Do I need a CWDM Mux/Demux to use this SFP?
A: No for a single point-to-point link, but a CWDM Mux/Demux is required to combine multiple wavelengths on one fiber pair.

Q: Is this a single-fiber (BiDi) optic?
A: No, it is a dual-fiber module using LC duplex connectors.

Q: Does it support digital diagnostics (DOM/DDM)?
A: Yes, it supports SFF-8472 digital diagnostics.

Q: What fiber type is required?
A: 9/125 µm single-mode fiber (SMF) is required for the specified reach.

Q: Is it compatible with 2 Gbps Fibre Channel switches?
A: Yes, if the switch supports 2G FC SFP optics and CWDM wavelengths.

Q: Can I mix different wavelengths on the same CWDM system?
A: Yes, provided each link uses matching wavelengths at both ends and the CWDM filter has those channels.

Q: Will I need an attenuator at short distances?
A: Possibly on very short spans if receiver overload occurs; check DOM readings and apply attenuation if required.
