FAQs

Q: Can this optic be used through a passive DWDM mux/demux?
A: Yes, ensure the mux/demux is 100 GHz C-band and the channel slot matches 1557.36 nm.

Q: Is any special patching required?
A: Use LC-LC single-mode patch leads and ensure proper polarity (A-to-B).

Q: What is the recommended fiber type?
A: OS1/OS2 single-mode fiber for best performance.

Q: Does it support monitoring of temperature and power?
A: Yes, via DOM/DDM.

Q: Is it backward compatible with SFP+?
A: No. This is a XENPAK form factor and requires a device with XENPAK slots.
