Description

Fixed-wavelength DWDM SFP for OC-48/STM-16 transport over single‑mode fiber. Aligned to the ITU-T G.694.1 100 GHz C-band grid at 1528.77 nm, this hot-swappable module provides reliable 2.5G line-rate for metro and long-haul links. Typical engineered spans of 40–80 km are achievable when paired with appropriate optical budget, amplification, and dispersion management. LC duplex interface on SMF simplifies integration into DWDM mux/demux systems and SONET/SDH platforms.

Features

- OC-48/STM-16 line-rate for SONET/SDH transport
- Fixed 100 GHz DWDM C-band wavelength (1528.77 nm)
- Hot-swappable SFP simplifies maintenance and sparing
- LC duplex interface on standard single‑mode fiber
- Engineered for metro/long-haul spans with amplification support

FAQs

Q: Is this module compatible with standard single‑mode fiber?
A: Yes, it is designed for SMF (G.652) with LC duplex connectors.

Q: What distance can I expect?
A: Typical engineered spans are 40–80 km depending on mux/demux loss, fiber attenuation, and whether amplification and dispersion management are used.

Q: Do I need a DWDM mux/demux?
A: Yes, DWDM transceivers must be matched with DWDM filters on the same ITU 100 GHz channel to operate in a DWDM system.

Q: Will it work at 1G or 10G?
A: No, it is intended for 2.5G OC-48/STM-16 line rates.

Q: Does it support LC connectors?
A: Yes, it uses an LC duplex optical interface.
