400G QSFP-DD FR4 Transceiver

Overview

400Gbps hot pluggable transceiver in QSFP-DD form factor
Optical connectivity based on two Singlemode Fiber (SMF) LC connectors
Optical engine use 4 uncooled 100 Gbps CWDM EML’s
The optical signals are modulated using a 4-level pulse amplitude modulation (PAM4) format
Optical Reach: up to 2km
Built in digital diagnostics – Transmitter
Power Monitoring (TPM) and Receive Signal Strength Indicator (RSSI)
RoHS-6 compliant
Operating case temperature range of 0°C to 70°C
Based on 100G Single Lambda MSA specification for
400G FR4 and on QSFP-DD baseline specification
