Description

DWDM SFP transceiver for SONET/SDH OC-48/STM-16 links, tuned to 1548.5 nm on the ITU-T 100 GHz C-band grid. Delivers 2.5G line-rate performance over single-mode fiber with LC duplex interface and typical reach up to 80 km (link budget and channel plan dependent). Ideal for long-haul DWDM mux/demux deployments where precise wavelength control is required.

Features

- Precise DWDM C-band wavelength (1548.5 nm) for multiplexed long-haul links
- 2.5G OC-48/STM-16 performance for carrier-grade transport
- LC duplex interface on single-mode fiber
- Typical 80 km reach for metro and regional DWDM networks
- Hot-swappable SFP for fast service turn-up and maintenance
- Compliant with ITU-T G.694.1 DWDM grid and SFP MSA

FAQs

Q: Is this module for Ethernet?
A: No. It is designed for SONET/SDH OC-48/STM-16 (2.5G) links, including POS over SONET. It is not intended for 1G/10G Ethernet.

Q: What DWDM channel/mux do I need?
A: Use a DWDM mux/demux port that matches the 1548.5 nm wavelength on the ITU-T 100 GHz C-band grid.

Q: What fiber and connector does it require?
A: Single-mode fiber (9/125 µm) with LC duplex connectors.

Q: How far can it reach without amplification?
A: Typical engineered links support up to ~80 km, but actual reach depends on total link loss, dispersion, and component quality.
