FAQs

Q: Is this SFP compatible with 100 GHz DWDM mux/demux systems?
A: Yes. It is tuned to a specific ITU 100 GHz C-band channel and works with matching 100 GHz DWDM filters.

Q: Will it work in any 1G SFP port?
A: Use in 1000BASE optical SFP ports that support DWDM optics. Check platform compatibility and approved transceiver lists.

Q: How far can it reach without amplification?
A: Up to 80 km is typical, subject to fiber loss, splices, and DWDM component insertion loss. Longer spans may require EDFAs/dispersion compensation.

Q: What connector does it use?
A: LC duplex for single-mode fiber.
