Description

DWDM fixed-wavelength SFP transceiver for OC-48/STM-16 links. Provides 2.488 Gb/s SONET/SDH transport over single-mode fiber using an LC duplex interface and an ITU-T G.694.1 C-band wavelength (1538.9 nm). Ideal for metro and long-reach DWDM applications when used with appropriate Mux/Demux and link budget design. Hot-swappable and MSA-compliant for broad platform interoperability.

Features

- DWDM fixed lambda for high-density optical multiplexing
- OC-48/STM-16 line rate for carrier-grade transport
- C-band 100 GHz ITU grid compatibility
- LC duplex interface on single-mode fiber
- Hot-swappable SFP MSA design
- Optimized for metro and long-reach deployments

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: Is this transceiver single-mode or multimode?
A: Single-mode (SMF) with LC duplex connector.

Q: What link distance can I expect?
A: Typically up to 80 km, subject to optical budget, fiber quality, and the use of DWDM amplification/dispersion compensation.

Q: Does it require a DWDM Mux/Demux?
A: Yes. It is a fixed DWDM wavelength and is intended for use with DWDM Mux/Demux systems.

Q: Which interfaces are supported?
A: OC-48/STM-16 (2.488 Gb/s) SONET/SDH interfaces on SFP ports that support DWDM optics.

Q: Is it hot-swappable?
A: Yes, it follows the SFP MSA and is hot-swappable.
