Models, specifications, and compatibility
Gigabit BIDI optical transceiver modules provide a transmission rate of 1250 Mbps and use LC connectors.
• BIDI optical transceiver modules use different central wavelengths in transmit and receive
directions to implement bidirectional transmission of fiber signals over the same fiber.
• You must use the HPE X122 1G SFP LC BX 10-D Transceiver (J9142B) and HPE X122 1G SFP
LC BX 10-U Transceiver (J9143B) in pairs: a J9142B (-D = downlink) at one end of the
connection and a J9143B (-U = uplink) at the other.
• The J9142B/J9143B were End of Sale in April 2016 and are no longer available. Contact your
Aruba Sales team for alternative solutions. The information presented here is for compatibility
use.
