FQDD-400G-EDR4
400Gbps QSFP-DD EDR4 2KM EML MPO transceiver
General description
FQDD-400G-EDR4 is a 400 Gbps Quad Small Form Factor Pluggable-Double Density (QSFP-DD) optical transceiver designed for 2km optical communication applications.
Functional description
ModSelL is an input pin. When held low by the host, this product responds to 2-wire serial communication commands. ResetL is a signal that allows the host to reset the module. A low level on the ResetL signal for longer than the minimum pulse length initiates a complete modulele reset, returning all all user module setting Sule settings tos to their default state. LPMode/TxDis is an input signal from the host operating with active high logic. If this pin is “high”, the module enters a low-power state. ModPrsL is used to indicate whether the module is plugged in on the connector, ModPrsL is pulled low when inserted and released to high when it is physically absent from the host connector. IntL/RxLOSL pin is used as interruption. When “Low”, it indicates a possible module operational fault, such as alarm and warning.
Absolute maximum ratings
It has to be noted that the operation in excess of any individual absolute maximum ratings might cause permanent damage to this module.
