Description

OC-48/STM-16 DWDM SFP for single‑mode fiber links, aligned to the ITU-T G.694.1 100 GHz C-band grid at 1531.9 nm. Delivers 2.5G line-rate for SONET/SDH transport with hot-swappable convenience. When properly engineered with adequate optical budget and, if needed, amplification and dispersion control, typical spans of 40–80 km are attainable. LC duplex interface integrates cleanly with DWDM mux/demux solutions.

Features

- 2.5G SONET/SDH OC-48/STM-16 transport capability
- Fixed DWDM C-band wavelength at 1531.9 nm (100 GHz grid)
- LC duplex single‑mode interface for long-distance links
- Hot-swappable SFP for streamlined maintenance
- Supports engineered metro/long-haul deployments with amplification

FAQs

Q: Is this module hot-swappable?
A: Yes, it is an SFP form factor designed for hot-swappable operation.

Q: Can it interoperate with other vendors’ DWDM systems?
A: Yes, provided the system supports OC-48/STM-16 and the same ITU 100 GHz channel, and optical budgets are compatible.

Q: What fiber connectors do I need?
A: LC duplex connectors on single‑mode fiber.

Q: Is amplification required?
A: For longer spans or higher-loss paths, EDFAs and dispersion management may be required to meet margin targets.
