SFP-1040-WB Product description
The SFP-1040-WB is a BiDirectional single fiber strand 10G SFP+ optical module using Tx:1330nm and Rx:1270nm wavelengths.
The transceiver supports all 10G rated speeds for Ethernet, SONET, SDH or Fibre Channel networks.
SFP-1040-WB must be paired with the SFP-1040-WA model to have an operational link.
The BiDirectional optical transceivers offer a great advantage of saving precious dark fiber and thus practically doubling the fiber capacity when compared with the traditional two strand modules.
