Cisco GLC-BX-U 1000BASE-BX10-U SFP Transceiver
1310nm Gigabit bidirectional SFP complementary to BX-D. Confirm exact product label and revision before applying specifications.
IDENTIFICATION: Confirm manufacturer PID, hardware revision, device ID or module suffix. Nominal standards/link rates are not measurements of payload performance.
Exact specifications and compatibility
| Dedicated subcategory | SFP transceivers: optical and copper |
|---|---|
| Exact product/model | Cisco GLC-BX-U 1000BASE-BX10-U SFP Transceiver |
| Bus, ports and physical interface | Hot-pluggable SFP with simplex LC; operates over one strand of single-mode fiber using internal WDM. |
| PHY, radio or protocol | 1000BASE-BX10-U; transmits 1310nm and receives 1490nm as complementary end to BX-D. |
| Nominal rate (not measured) | 1Gb/s nominal rate; Cisco specifies up to 10km with matching D module and compliant optical link budget. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | No NIC driver. Host port must qualify this PID; DOM readout is dependent on module revision and switch support. |
| Compatibility | Requires single-mode fiber and complementary GLC-BX-D/1000BASE-BX10-D at far end. Wavelength direction matters. |
| Variant warning | GLC-BX-U is not interchangeable with BX-D or another U module. Different BX10/40/80 reach classes require matched endpoint. Verify suffix. |
