XFP - 10GBASE-BX XFB23020101D - XFB2302010xD is a high performance XFP transceiver module for 10 Gigabit Ethernet data links over one single mode fibre. The maximum reach is 20km. The transmitter is a 1270nm DFB laser, the receiver is a 1330nm PIN photodiode. Consequently, a module with a 1330nm transmitter and a 1270nm receiver is required at the opposite side of the link. The recommended counterpart is XFB3202010xD. This transceiver module is compliant with the Small Form-factor Pluggable (XFP) Multisource Agreement (MSA) and hot pluggable.
