FAQs

Q: Is this a tunable DWDM SFP+?
A: No. It is a fixed-wavelength DWDM module at 1535.82 nm on the ITU-T 100 GHz grid.

Q: What distance can it support?
A: Up to 40 km over single-mode fiber under standard link budget conditions. Actual reach depends on fiber loss, splices, connectors, and DWDM components.

Q: Does it support DOM/DDM?
A: Yes. Digital Optical Monitoring is supported for parameters like temperature, voltage, TX power, and RX power.

Q: Which connector and fiber type are required?
A: Duplex LC connector with single-mode fiber (SMF).

Q: Can I use it without a DWDM MUX/DEMUX?
A: It can operate point-to-point at its fixed wavelength, but it is designed for DWDM systems using MUX/DEMUX or OADMs.

Q: Is it hot-swappable?
A: Yes. It can be inserted or removed without powering down the host device.

Q: Do I need an attenuator for short links?
A: For very short spans, an optical attenuator may be required to prevent receiver saturation. Follow your platform’s optical power guidelines.
