Description

DWDM SFP for SONET/SDH OC-48/STM-16 applications using single-mode fiber, providing a fixed ITU-grid wavelength for dense optical multiplexing. Suitable for metro-core to long-haul links where precise channel alignment and hot-swap convenience are required.

Features

- Designed for OC-48/STM-16 SONET/SDH networks
- Fixed DWDM wavelength for dense optical channel plans
- Hot-swappable SFP form factor
- LC duplex on SMF for low-loss connections
- Supports long-haul designs with appropriate amplification/compensation

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: Will this module work in OC-48/STM-16 ports that accept DWDM SFPs?
A: Yes. Ensure your host platform and software release support DWDM SFPs at OC-48/STM-16 rates.

Q: Is the wavelength tunable?
A: No. It is a fixed-wavelength DWDM optic; select the exact wavelength required by your DWDM channel plan.

Q: What connector and fiber are required?
A: LC duplex connectors on single-mode fiber.

Q: Can it be used with existing DWDM MUX/DEMUX hardware?
A: Yes, provided the channel wavelength matches and the optical budget is sufficient for the span.
