NOTE:
•
BIDI fiber transceiver modules use different central wavelengths in transmit and receive directions, in
order to implement bidirectional transmission of optical signals over the same fiber.
• You must use the SFP-FE-LX-SM1310-BIDI and SFP-FE-LX-SM1550-BIDI transceiver modules in pairs.
Gigabit BIDI fiber transceiver module
See Figure 8 for a view of the Gigabit BIDI fiber transceiver module.
