The SFP-10G-BX-U20-C is a Cisco-compatible 10GBASE-BXU SFP+ transceiver module designed for single-mode fiber links up to 20 km using bidirectional (BiDi) WDM technology.
The module supports a fixed 10 Gbps data rate, fully compliant with IEEE 802.3ae 10GBASE specifications for high-speed network links.
It uses single-mode fiber (SMF) with an LC duplex connector, enabling low-loss, high-bandwidth transmission over 20 km links.
The SFP-10G-BX-U20-C supports up to 20 km link distance on single-mode fiber under standard conditions.
This BiDi module transmits at 1271 nm and receives at 1331 nm (or vice versa, depending on direction), enabling single-fiber operation with WDM.
While it is not Cisco-branded, the SFP-10G-BX-U20-C is fully compatible with Cisco switches and routers, passing interoperability tests for seamless integration.
Yes, the module supports SFF-8472 DOM, providing real-time monitoring of optical power, temperature, voltage, and transceiver status via the host interface.
The module operates between 0 °C and 70 °C (32 °F to 158 °F), suitable for most data center and enterprise environments.
Yes, it adheres to the SFP+ MSA (Multisource Agreement) for mechanical, electrical, and optical interoperability across vendor equipment.
Power off the port, insert the SFP-10G-BX-U20-C into the SFP+ slot until it clicks, then power on the device and verify link status in your switch’s interface.
Use your switch’s CLI or GUI to check port status; look for ‘up’ state and confirm DOM readings for Tx/Rx power and temperature via SFF-8472 commands.
Yes, as long as the other modules are SFF-8431 and SFF-8432 compliant, you can interoperate without performance loss across vendor equipment.
Typical power consumption is 1.0 W maximum, ensuring minimal impact on your switch’s power budget.
Yes, maintain correct BiDi polarity: use single-strand fiber with the proper Tx/Rx wavelength orientation to prevent link failure.
It includes a one-year limited warranty covering manufacturing defects; extended support plans may be available through your vendor.
Ideal for data center interconnects, metro Ethernet, and long-haul enterprise links where single-fiber BiDi transmission reduces cabling complexity.
