This Cisco compatible SFP28 transceiver provides 25GBase-BX throughput up to 40km over single mode fiber (SMF) using a wavelength of 1270nm-TX/1310nm-RX via an LC simplex connector. This bidirectional unit must be used with another transceiver or network appliance of complimenting wavelengths. It provides 25GBASE Ethernet connectivity option for 25G Ethernet, telecom and data center. It is fully compliant with the SFP28 MSA, CPRI and eCPRI standard.
Note: The FS P/N is changed from SFP28-25G-BX40 to SFP-25G23-BX40, but the product is the same. Only the FS P/N has been changed.

Part Number: SFP-25G23-BX40
