Description

DWDM SFP transceiver for OC-48/STM-16 over single‑mode fiber, aligned to ITU-T G.694.1 100 GHz C-band at 1531.1 nm. Provides reliable 2.5G transport for metro aggregation and long-haul systems. With appropriate link engineering (optical budget, EDFAs, and dispersion control), typical spans of 40–80 km are achievable. LC duplex interface ensures straightforward deployment with DWDM mux/demux filters.

Features

- Fixed 1531.1 nm DWDM wavelength on the ITU 100 GHz grid
- OC-48/STM-16 2.5G line-rate for SONET/SDH networks
- Hot-swappable SFP for simplified operations
- LC duplex SMF interface for long-distance transport
- Engineered for metro/long-haul with amplification/dispersion options

FAQs

Q: Does this optic support OC-48 only, or also Gigabit Ethernet?
A: It is designed for SONET/SDH OC-48/STM-16 line rates, not for 1G Ethernet.

Q: How do I ensure wavelength compatibility?
A: Match the transceiver’s fixed wavelength (1531.1 nm) with the corresponding DWDM mux/demux channel in your design.

Q: Is special dispersion management required?
A: For longer spans, dispersion compensation and amplification may be required based on link budget and fiber characteristics.

Q: What connector type is used?
A: LC duplex on single‑mode fiber.
