Cisco compatible SFP-10G-BX-U-80KM Description
EdgeOptic's SFP-10G-BX-U-80KM compatible is a Cisco-coded version of the EdgeOptic BIDI-10G-SFP-80A multi-vendor 10G BiDi SFP+ transceiver. It carries Cisco-recognized EEPROM so Cisco switches and routers identify it as an SFP-10G-BX-U-80KM, and it matches the optical specification of the original 10GBASE-BX80-U module for transmit wavelength, receive wavelength, link budget, and reach.
This is a single-fiber bidirectional module. It transmits at 1490 nm and receives at 1550 nm over one strand of single-mode fiber, reaching 80 km. The transmit side uses an EML laser with output power of 0 to +5 dBm; the receive side uses an APD photodiode rated to −23 dBm sensitivity and −7 dBm overload. Average link budget is 23 dB and the module tolerates up to 1600 ps/nm of chromatic dispersion, which is what carries the signal across the full 80 km span. The connector is a single LC/UPC and digital diagnostics (DOM) are supported.
Because it is a BiDi module, it works as a complementary pair. The SFP-10G-BX-U-80KM at Tx1490/Rx1550 needs a Tx1550/Rx1490 module at the far end of the same fiber. The matching EdgeOptic part is the BIDI-10G-SFP-80B root product, the downstream Cisco SFP-10G-BX-D-80KM compatible. Verify both ends run opposite wavelength directions during commissioning, otherwise the link will not come up.
Because the EEPROM is Cisco-coded, the module is recognized on Cisco switches and routers without the service unsupported-transceiver command. The 80 km reach is ZR class, so the optics follow the SFP+ MSA (SFF-8431) and STM-64 framing rather than the shorter-reach Ethernet PMDs. Line rates run from 1.25 to 11.32 Gbps, covering 10 Gigabit Ethernet (10.31 Gbps), Gigabit Ethernet (1.25 Gbps), 1G/2G/4G/8G/10G Fibre Channel, and STM-64 (9.95 Gbps). The module runs on a single +3.3V supply across a 0 to 70°C operating range, and compliance covers SFF-8431, the SFP MSA, CE, RoHS, and Class 1 laser safety per FDA and IEC 60825-1.
