SFP+ - 10GBASE-BX SPB32020100B - SPB3202010xB is a high performance transceiver module for up to 10x Gigabit Ethernet data links over a single mode fibre. The maximum reach is 20km. The transmitter is a 1330nm DFB laser, the receiver a 1270nm PIN photodiode. Consequently, a module with a 1270nm transmitter and a 1330nm receiver is required at the opposite side of the link. The recommended companion is SPB2302010xx. 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.
