SPB32B21L6xD is a high performance transceiver module for CPRI/OBSAI up to 6.144G data links over a single mode fibre. The maximum reach is 60km, with 21dB End Of Life (EOL) power budget. The transmitter is a 1330nm DFB laser, the receiver a 1270nm APD (Avalanche Photodiode). Consequently, a module with a 1270nm transmitter and a 1330nm receiver is required at the opposite side of the link. The recommended counterpart is SPB23B21L6xD. This transceiver module is compliant with the Small Form-factor Pluggable (SFP+) Multisource Agreement (MSA) and hot pluggable.
