FAQs

Q: Can this be used for Ethernet traffic?
A: It is intended for SONET/SDH OC-48/STM-16 transport, including POS over SONET. It is not for standard 1G/10G Ethernet.

Q: Do I need a matching DWDM channel on the mux?
A: Yes. The mux/demux must have a 1549.32 nm (100 GHz) port to match this optic.

Q: Which fiber and connector type are required?
A: Single-mode (9/125 µm) fiber with LC duplex connectors.

Q: What is the unamplified reach?
A: Typically up to ~80 km, depending on total optical loss and dispersion management.
