AVDAT 4X™ is the first drop-in optical interconnect replacement for InfiniBand 4X Electrical Connector. AVDAT 4X™ is a highly compact four-lane optical transceiver ideal for use in InfiniBand™ SDR/DDR, 10Gb Ethernet XAUI optical interfaces and Fibre Channel switches. AVDAT 4X features an aggregate bandwidth of 20 GBaud in each direction over a standard multimode 12-fiber ribbon with MPO ribbon fiber connectors.
 
Optical, electrical and high-speed signaling specifications are compliant with InfiniBand™ SDR/ DDR specifications. The AVDAT 4X™ signal, reaches at 5 GBaud line rate per channel, are longer than 75 and 100 meters over 62.5um and 50um MMF, respectively.

The AVDAT 4X transceiver is footprint and contact-pattern compatible with CX4, four-channel electrical connector receptacle defined by InfiniBand™ Architecture. Host board changes are not required to insert an AVDAT transceiver in place of an electrical CX4 receptacle.

Integrated into the product board, AVDAT 4X contributes to increased overall system reliability, involving less external copper-to-fibre connections.
With minimal MTP®/MPO fiber cable bending radius, and full flexibility in cable length selection, AVDAT 4X provides the highest serviceability solution for large and complex fabrics.
