FAQs

Q: Do I need a matching transceiver at the far end?
A: Yes. Use the complementary U unit (1270Tx/1330Rx) on the remote side for a working BiDi link.

Q: Can this module be used with duplex LC patch cords?
A: No. It uses LC simplex and requires a single SMF strand per link.

Q: Is forward error correction (FEC) required?
A: FEC is recommended on 25G links to improve margin, especially on long-reach optics.
