FAQs

Q: Does this module support Ethernet?
A: It supports SONET/SDH OC-48/STM-16 transport (including POS over SONET) and is not intended for standard Ethernet rates.

Q: Which DWDM channel port should I select on the mux?
A: Use the port corresponding to 1550.9 nm on a 100 GHz C-band DWDM mux/demux.

Q: What cabling do I need?
A: Single-mode fiber (9/125 µm) with LC duplex connectors.

Q: How far will it reach without optical amplification?
A: Typically up to ~80 km, depending on span loss, connectors/splices, and dispersion.
