SBD43020FExx is a high performance transceiver module for Fast Ethernet data links over a singlemode fiber pair. The maximum reach is 20km. The emitter is a 1490nm DFB laser, the receiver a 1310nm PIN photodiode. Consequently, a module with a 1310nm emitter and a 1490nm receiver is required at the other side of the link. The recommended companion is SBU34020FExx. This transceiver module is compliant with the Small Form-factor Pluggable (SFP) Multisource Agreement (MSA) and hot pluggable.
