Molex Incorporated will unite with other Optical Internetworking Forum (OIF) members to showcase 56 Gbps Common Electrical Interface (CEI) solutions during live technology demonstrations at the OIF, which was held in Los Angeles, March 24-26, 2015. The OIF Technology Showcase 2015, called “It’s Happening Now – 56G Electrical Interfaces and Pluggable Coherent Optics,” highlighting breakthrough technology driven by OIF members. The OIF’s 4th generation project, CEI-56G, is helping the industry achieve higher CEI data rates than ever before.
“By successfully demonstrating 56 Gbps solutions, Molex and its OIF partners are helping to create next-generation, high-speed connectivity,” said Scott Sommers, group product manager, Molex. “The OIF is facilitating rapid progress on technically complete documentation that can be used to develop compliant products. This is crucial to meeting the high-performance needs of current and future communications systems that enable multi-vendor interoperability.”
Three of the live OIF demonstrations showcasing Molex interconnects:
•A CEI-56G-VSR-PAM4 QSFP compliance board demo will test 56 Gbps data rates with a PAM4 module. It will demonstrate the ability to transmit and receive PAM4 signals across a commercially available connector using test equipment from Tektronix. One demonstration uses a Tektronix PAM4 signal generator to transmit PAM4 formatted data over a QSFP connector using test boards from Molex. The PAM4 receiver is provided by Multilane.
•A CEI-56G MR/LR PAM4 backplane demo, including a Molex MR/LR backplane and Keysight PAMs, will showcase the ability of PAM4 signaling to operate over a backplane. This demo uses Keysight test equipment to generate and receive PAM4 formatted data sent over a Molex backplane consisting of two line cards with Impel backplane connectors on a MR/LR compliant backplane. This demo has been performed for the past three years, but the data rate has doubled to 56 Gbps compared to last year’s demo, which featured a speed of 28 Gbps.
•A CEI-56G-MR NRZ compliant SERDES IC will transmit 56 Gbps NRZ live serial traffic on the zQSFP+ form factor across a high-speed copper cable infrastructure. The demonstration will highlight the feasibility of running extremely high, next-generation data rates, even on current form factors. Credo will supply transmitting and receiving electronics and will drive a cable assembly using a 50 Gbps, NRZ-encoded data stream, demonstrating this new level of performance at acceptable BER across existing interconnects. The demo will use a Molex zQSFP+ cable assembly and a zQSFP+ SMT connector interface. This demo uses Credo SERDES ICs on evaluation boards to send 50 Gbps NRZ data across high-speed copper cables supplied by Molex. Keysight test equipment is used to show eye diagrams.
