Brazilian Customs Clearance Optical Transmitter QSFP-DD
The QDD-200G-SR8 Transceiver is designed to transmit and receive serial optical data links up to 28 Gb/s data rate(per channel) over multi-mode fiber. It is a small-form- factor hot pluggable transceiver module integrated with the high performance VCSEL laser and high sensitivity PIN. The latest addition to the Cisco portfolio pushes this boundary further with the introduction of the 400G QSFP-DD High-Power (Bright) Optical Module. Cisco 400G QSFP-DD High-Power (Bright) Optical module Cisco is now expanding the range of 400G Digital Coherent QSFP-DD. QSFP-DD (quad small form-factor pluggable double density) doubles the capacity of QSFP interconnects with an eight-lane electrical interface capable of 28 Gbps NRZ, 56 Gbps PAM4, and 112 Gbps PAM4 to achieve up to 800 Gbps per port. They are compliant with the QSFP-DD MSA, and portions of IEEE P802. Digital diagnostic functions are available Finisar Application Note AN-2189.
