The battle for next-generation optical transceivers remains active. The three leading specifications duking it out include COBO, OSFP and QSFP-DD. While all have their pros and cons, the industry continues to sort out the best solutions for the front panel and mid-board optical engines. What is QSFP-DD? Current QSFP solutions meet the existing demands of the telecom/datacom industries. The QSFP-DD MSA focuses on a next generation high-density, high-speed pluggable backwards … [Read more...]
QSFP-DD and FQSFP-DD: Not Your Brother’s Quad Small Form Factor Pluggable!
Quad Small Form Factor Pluggable (QSFP) has become the workhorse pluggable module form factor. Originally intended as the next step past SFP/SFP+, QSFP supports data rates at 10 Gbps per channel (40 Gbps aggregate) and 25 Gbps per channel (100 Gbps aggregate). The current QSFP solution meets the demands of the telecom/datacom industries, for now. As advanced ASIC and FPGA solutions hit the market, a next generation module that overcomes the limitations of QSFP needs to perform at 50 Gbps+ per … [Read more...]
