L9-FC554901-80PPC 1×9 155Mbps 80km FC Optical Transceiver Module

L9-FC554901-80PPC is a long-reach 1×9 form-factor optical transceiver designed for 155 Mbps single-fiber bi-directional optical transmission. The module operates at Tx 1550 nm / Rx 1490 nm, supports transmission distances of up to 80 km, and uses an FC optical connector for reliable long-distance single-mode fiber links.

With a wide DC input voltage range of 5.5-26 V and a TTL electrical interface, this transceiver is optimized for air-to-ground UAV optical links, FPV systems, single-fiber video converters, and serial data transmission over fiber.
