Description

Compact CWDM SFP for SONET/SDH OC-3/STM-1 links over single‑mode fiber. This 1550 nm module enables long-distance transport through passive CWDM mux/demux systems, using an LC duplex interface and hot‑swappable SFP form factor. Ideal for metro aggregation and ONS transport where wavelength density and fiber efficiency matter.

Features

- 155 Mb/s OC-3/STM-1 over single-mode fiber
- CWDM wavelength: 1550 nm for high fiber utilization
- Long-reach SMF performance up to 80 km (budget dependent)
- LC duplex interface; SFP hot-swappable for easy serviceability
- Optimized for CWDM mux/demux metro and transport applications
- Interoperable with platforms that support OC-3/STM-1 CWDM SFPs

Technical Specifications

FAQs

Q: Is this module single-mode or multimode?
A: Single-mode (9/125 µm) with LC duplex connector.

Q: What distance can it support?
A: Up to 80 km is typical, subject to fiber quality, splice/connect losses, and overall optical budget.

Q: Does it work with non-CWDM optics on the far end?
A: No. CWDM links require the same CWDM wavelength module at both ends, usually through a passive CWDM mux/demux.

Q: Can I use this for Ethernet links?
A: It is designed for SONET/SDH OC-3/STM-1. It is not intended for Ethernet standards.

Q: How do I ensure compatibility?
A: Use in SFP ports that explicitly support OC-3/STM-1 and CWDM wavelengths, and match the 1550 nm wavelength on the remote end.
