Description

High-density 10G DWDM X2 transceiver designed for metro and long-haul 10GbE over single-mode fiber. Tuned to the ITU-T C-band channel at 1539.77nm with up to 80km reach (design dependent), it uses a duplex SC interface and integrates seamlessly into platforms with native X2 ports or via X2-to-SFP+ adapters. Ideal for DWDM mux/demux backbones and dark fiber extensions.

Features

- Tuned DWDM wavelength at 1539.77 nm for C-band networks
- Long-reach 80 km performance for metro/long-haul 10G links
- Duplex SC interface for robust X2 deployments
- Standards-based ITU-T DWDM grid for interoperability
- Ideal for dark fiber and DWDM backbone aggregation

FAQs

Q: Is this module compatible with platforms that have X2 10G slots?
A: Yes, it fits devices with native X2 interfaces. It can also be used with supported X2-to-SFP+ adapter modules where available.

Q: Do I need a DWDM mux/demux to use this optic?
A: For multi-channel DWDM systems, a compatible DWDM mux/demux is required. Point-to-point single-channel use over the specific wavelength is also possible.

Q: Can it operate over multimode fiber?
A: No. This transceiver is designed for single-mode fiber only.
