NADDOD optimizes PCB routing to reduce EMI and supply voltage of functional circuits. The 200G QSFP-DD is made of high-quality materials, the package size is longer, the internal space is larger enough to dissipate heat.
The 200G QSFP-DD transceviers adopt NRZ modulation cheme with total rate of transmission up to 212.5Gb/s, which can be downward-compatible with most QSFP transceviers. NRZ modulation cheme has lower power consumption than "PAM4" of QSFP56, can optimize OPEX and cooling efficiency of data centers, realizing low latency and BER of 1E-15 with FEC off.
NADDOD has a full range of professional testing equipments for testing various parameters of products to ensure high performance and quality of optical transmission stability.
