This QuickTreX® transceiver is a quad small form-factor pluggable module for serial optical data communications such as IEEE 802.3cd 400GBASE-SR8. The 400G QSFP-DD SR8 is a 8x 26.5625Gbd multi-mode fiber, hot pluggable optical transceiver. It is with the QSFP-DD 38-pin connector to allow hot plug capability. The internally ac coupled high speed serial I/O simplifies interfacing to external circuitry. A serial EEPROM in the transceiver allows the user to access transceiver digital diagnostic monitoring and configuration data via the 2-wire QSFP Management Interface. 

Transmitter Section
The transmitter section uses Vertical Cavity Surface Emitted Lasers (VCSEL).In addition, this component is also class 1 laser that compliant with International Safety Standard IEC-60825-1:2014. It complies with EN60825-1:2014/A11:2021 and FDA 21 CFR 1040.10 and 1040.11 

Receiver Section
The receiver incorporates GaAs PIN photodiodes integrated with trans-impedance preamplifiers (TIA) and limiting post-amplifier ICs.
