Description
The F-tone Networks FTQD-4H-DR4xx is a transceiver module designed for 2km optical communication applications, and it is compliant to QSFP-DD MSA, IEEE 802.3bs protocol and 400GAUI-8 standards. The 425 Gigabit signal is carried over four parallel lanes by one wavelength per lane. This module can convert 8-channel 53.125 Gbit/s electrical data to 4 parallel channels of optical signals, each supporting106.25 Gbit/s data transmission. Reversely, it can convert 4-channel 106.25 Gbit/s optical signals to 8-channel electrical output data on the receiver side. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.
