Work is Underway for Development of 40 Gbps Compact, Low Power Pluggable Transceiver Module for providing 40 Gbps Serial Transmission to High Capacity Network and Storage systems
Mitsubishi Electric along with Oki Semiconductor, Opnext, Renesas Electronic and Sumitomo Electric Industries have announced Multi-Source Agreement (MSA) agreement in creating a transmitter optical sub-assembly (TOSA) and receiver optical sub-assembly (ROSA) for 40 Gbps pluggable transceiver modules. The member company will specify the common mechanical dimensions, footprint, pin functions as well as performance of the optical transmitter and receiver devices. Furthermore, MSA will specify key features including a low-profile and compact form factor pluggable modules with simple electrical interfaces which will provide a cost effective solution to the market.
The 40 Gbps is the highest commercially available modulation speed, which uses the simple light on/off keying or serial transmission scheme. The 300-pin MSA using 1550 nm light source devices are widely used for the 2km applications, plus the recently demonstrated 40 Gbps serial transmission over 10 km using 1310 nm light source. The new TOSA/ROSA MSA defines both the laser transmitter devices as well as the PIN Photodiode Trans-impedance amplifier (PIN-TIA) receiver devices which comply with 40 Gbps interface standards. The aim of the MSA is the development of modules for more than 10 km applications.
