FAQs

Q: Can this be used with a CWDM mux on the 1490 nm channel?
A: Yes. It is tuned for the 1490 nm CWDM wavelength and pairs with the corresponding mux/demux port.

Q: Does it support lower Fibre Channel speeds?
A: Yes. It is backward-compatible with 2G and 4G FC when supported by the host.

Q: What fiber type is recommended?
A: Single-mode OS1/OS2 with LC duplex connectors.

Q: What is the typical maximum reach?
A: Up to 10 km, depending on total optical loss and system margins.

Q: Is DOM/DDM available?
A: Yes. Digital diagnostics are supported for real-time monitoring.
