Description

High-efficiency CWDM SFP for OC-3/STM-1 links at 1590 nm over single‑mode fiber. Suited for wavelength-division transport through passive CWDM mux/demux gear, with LC duplex connectivity and a hot‑swappable SFP form factor for rapid maintenance and turn-up.

Features

- 1590 nm CWDM wavelength for high channel density
- Supports 155 Mb/s SONET/SDH OC-3/STM-1
- Long-haul SMF capability up to 80 km (budget dependent)
- LC duplex, SFP hot-swap design simplifies maintenance
- Optimized for passive CWDM mux/demux transport
- Broad platform interoperability where OC-3 CWDM SFPs are supported

FAQs

Q: Can I mix this 1590 nm module with another CWDM wavelength on the far end?
A: No. Both ends must use the same wavelength (1590 nm) to establish a link.

Q: What environments is this best suited for?
A: Metro/access transport, ONS platforms, and any CWDM-enabled OC-3/STM-1 aggregation where fiber is scarce.

Q: Does it require special fiber?
A: Standard single-mode fiber (9/125 µm) is sufficient.

Q: How is maximum distance determined?
A: By the optical link budget, accounting for fiber attenuation, splices, connectors, and any passive mux/demux insertion loss.

Q: Is there digital diagnostics (DOM/DDM)?
A: Support varies by platform; consult platform documentation for DOM/DDM availability with CWDM OC-3 SFPs.
