Overview

The QDD-400G-DR4-FL is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP56-DD) optical module designed for 500m optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. Reversely, on the receiver side, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 8 channels of 50Gb/s (PAM4) electrical output data.

Applications

Optical Port Description

The optical port is an MPO-12 APC receptacle carrying 4 transmit and 4 receive single-mode fibers. Proper alignment is ensured by the guide pins inside the receptacle; the cable should not be twisted, to keep channel-to-channel alignment.

Average launch power, each lane (min) is informative and not the principal indicator of signal strength. A transmitter with launch power below this value cannot be compliant; however, a value above this does not ensure compliance.
Even if the TDECQ < 1.4 dB for an extinction ratio of ≥ 5 dB, or TDECQ < 1.1 dB for an extinction ratio of < 5 dB, the OMAouter (min) must exceed the minimum value specified here.
Ceq is a coefficient defined in IEEE Std 802.3-2018 clause 121.8.5.3 which accounts for reference equalizer noise enhancement.
Average receive power, each lane (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.
The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with a value of SECQ up to 3.4 dB, where SECQ is the SECQ of the transmitter used to measure the receiver sensitivity.
Measured with conformance test signal at TP3 for a BER of 2.4×10⁻⁴.
These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.

Digital Diagnostic Functions

The following digital diagnostic characteristics are defined over the normal operating conditions unless otherwise specified.

Parameter	Symbol	Min	Max	Unit	Notes
Temperature monitor absolute error	DMI_Temp	-3	3	°C	Over operating temperature range
Supply voltage monitor absolute error	DMI_VCC	-0.1	0.1	V	Over full operating range

Channel bias current monitor absolute error	DMI_Ibias_Ch	-10	10	%
Channel TX power monitor absolute error	DMI_TX_Ch	-2	2	dB	1

Due to measurement accuracy of different single-mode fibers, there could be an additional ±1 dB fluctuation, or a ±3 dB total accuracy.
