Avago Technologies has announced the availability of 120-Gb/s multichannel optical transmitter and receiver modules for inside-the-box data center applications and a CXP pluggable transceiver for board-edge box-to-box and rack-to-rack communications.

The parallel multichannel MiniPOD optical transmitters/receivers and CXP optical transceivers solve bandwidth density problems in data centers.

Driven by the demand for online media and applications in cloud computing, the modules are suitable for communications within data centers, server farms, network switches and telecom switching centers. System applications include data aggregation, backplane communications and proprietary protocol data transfers.

The stand-alone MiniPOD transmit and receive modules, the AFBR-81uVxyZ and AFBR-82uVxyZ, respectively, contain 12 unidirectional channels that can each transfer data at 10.3125 Gb/s using 64b/66b encoding for an aggregate data rate of 120 Gb/s for each module. The CXP pluggable edge-mount transceiver module, AFBR-83PDZ, contains 12 transmit and 12 receive lanes that operate at the same data transfer rates as the MiniPOD modules.

The MiniPOD optical modules and CXP transceiver can transmit data up to 100 m using OM3 fiber, and up to 150 m using OM4. All the optical components employ proprietary vertical-cavity surface-emitting laser arrays operating at 850 nm for the transmitters and the company’s PIN diode array for the receivers.

The MiniPOD modules are available in two package options to support flat ribbon or round fiber jumper cables.
