The SFP-1010-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-1010-WB must be paired with the SFP-1010-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. The SFP-1010-WB has been tested and found 100% compatible with Cisco, Juniper, Force10 and many other networking equipment vendors.
