FAQs

Q: Can I use this CWDM SFP with a passive CWDM MUX/DEMUX?
A: Yes. It uses a fixed 1530 nm CWDM wavelength aligned to the ITU-T grid and is suitable for passive CWDM multiplexers/demultiplexers.

Q: Is multimode fiber supported?
A: No. This transceiver is designed for single-mode fiber (SMF) with LC duplex connectors.

Q: Does it support digital diagnostics (DOM/DDM)?
A: Yes. It provides DOM/DDM for monitoring parameters such as temperature, supply voltage, TX bias, and optical power.

Q: Is it hot-swappable?
A: Yes. It can be inserted or removed without interrupting chassis operation.

Q: What base standard applies to the 40 km variant?
A: It aligns with 1000BASE-EX reach for up to 40 km over SMF.

Q: Can different CWDM wavelengths interoperate?
A: Yes, when paired through a CWDM MUX/DEMUX. Each end must use matching wavelengths and compatible optics.
