System compatibility
1000BASE-BX-U is Extreme original bidirectional single-fiber gigabit SFP transceiver. Compatible with Extreme Summit X440, X450a, VSP series switches equipped with SFP slots. It must be paired with 1000BASE-BX-D module on the opposite fiber end. Supports DDM real-time monitoring of optical power, temperature and supply voltage. Widely applied in enterprise campus and factory gigabit links when fiber cores are limited.
Function
1000BASE-BX-U uses WDM bidirectional transmission technology, sending and receiving optical signals on one single-mode fiber. It transmits at 1310nm and receives at 1490nm, matched with 1000BASE-BX-D. DDM function can read real-time working parameters of the transceiver. This module saves fiber resources for 10km gigabit point-to-point singlemode fiber links.
Installation
Wear ESD anti-static wrist strap. Insert the SFP module fully into the SFP port of switch. Connect LC simplex singlemode fiber patch cord. Ensure the remote side uses 1000BASE-BX-D. Power on the equipment, verify module identification, DDM optical power reading and link status via switch CLI before commissioning.

FeatureOriginal Extreme 1000BASE-BX-U SFP bidirectional optical transceiver,1310nm TX /1490nm RX,10km single fiber transmission,built-in DDM digital diagnostic function,hot-pluggable,simplex LC interface,low power consumption. This spare is designed for gigabit fiber links with insufficient fiber cores.
DiagnosticModule undetected: Check gold finger cleanliness, SFP port health. No optical link: Verify fiber polarity, singlemode fiber quality and confirm remote module is 1000BASE-BX-D. Low transmit / receive optical power alarm: Dirty fiber endfaces or damaged singlemode fiber cables. DDM read failure: Confirm switch firmware supports DOM function. Over-temperature alarm: Check equipment cabinet ventilation and heat dissipation.
