FAQs

Q: What fiber and connectors are required?
A: Use single-mode (OS1/OS2) LC-LC duplex fiber patch cords.

Q: Can this module interoperate with another vendor at the far end?
A: Yes, interoperability is possible when the far-end optics match OC-48/STM-16 S-16.1 at 1310 nm and equivalent optical budgets.

Q: Is this for Ethernet traffic?
A: No. It is designed for SONET/SDH (OC-48/STM-16) framed transport, not Ethernet.

Q: Does it require special configuration?
A: It is a hot-swappable SFP; platform configuration typically involves selecting the SONET/SDH rate and interface on the host port.
