SFP - 1000BASE-BX SBD43010GE2B - SBD43010GExB is a high performance SFP transceiver module for Gigabit Ethernet data links over one single mode fibre. The maximum reach is 10km. The transmitter is a 1490nm DFB laser, the receiver is a 1310nm PIN photodiode. Consequently, a module with a 1310nm transmitter and a 1490nm receiver is required at the opposite side of the link. The recommended counterpart is SBU34010GExx. This transceiver module is compliant with the Small Form-factor Pluggable (SFP) Multisource Agreement (MSA) and hot pluggable. This part number is a Skylane Generation B transceiver. This part number is a Skylane Generation B transceiver.
