FAQs

Q: What wavelength is this module tuned to?
A: 1542.94 nm on the ITU-T C-band, 100 GHz grid.

Q: Is it suitable for 40 km links?
A: Yes. It supports up to 40 km over OS1/OS2 SMF, subject to the link loss budget.

Q: Does it require single-mode fiber?
A: Yes. Use OS1/OS2 single-mode fiber with duplex LC connectors.

Q: Can I monitor optical power levels?
A: Yes. DOM provides Tx/Rx optical power and other diagnostics.

Q: Can I use it without a DWDM mux?
A: Yes. For point-to-point links, deploy matching wavelength modules at both ends.
