Description

Fixed-wavelength DWDM SFP+ transceiver for high-density 10G backhaul and metro aggregation. Supports ITU-T 100 GHz DWDM grid in the C-band with LC duplex interface and digital diagnostics for simplified monitoring. Ideal for use with passive DWDM mux/demux systems in long-reach single-mode deployments (link-budget dependent).

Features

- Fixed 1531.12 nm DWDM wavelength on the ITU 100 GHz grid
- Long-reach 10G over single-mode fiber (up to 80 km)
- LC duplex interface for straightforward patching
- EML/APD optics for high sensitivity and stability
- Digital diagnostics for proactive monitoring
- Interoperates with passive DWDM mux/demux systems
