FAQs

Q: Is this a DWDM transceiver?
A: Yes. It operates at a fixed DWDM C-band wavelength of 1551.72 nm on the ITU 100 GHz grid.

Q: What fiber and connector do I need?
A: Use single-mode fiber (OS2 recommended) with a duplex LC connector.

Q: Will it reach 40 km without amplification?
A: Yes, under typical loss budgets. Actual reach depends on fiber attenuation, splices, connectors, and dispersion.

Q: Does it support DOM/DDM?
A: Yes. It provides digital optical monitoring for key parameters such as temperature, TX/RX power, and voltage.

Q: Which applications are supported?
A: 10G Ethernet (10GBASE-ER) DWDM links; check your platform for specific protocol support.
