QSFP DD 400G LR4 SMF Fiber Optic Transceiver 10KM with FEC DDM
Duplex LC
This product is a 400Gb/s Quad Small Form Factor Pluggable-double
density (QSFP-DD) optical module designed for 10km optical
communication applications. The module converts 8 channels of
50Gb/s (PAM4) electrical input data to 4 channels of CWDM optical
signals, and
multiplexes them into a single channel for 400Gb/s optical
transmission. Reversely, on the receiver side, the module optically
de-multiplexes a 400Gb/s optical input into 4 channels of CWDM
optical signals, and converts them to 8 channels of 50Gb/s (PAM4)
electrical output data.

Note:
1. 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.
2. Even if the TDECQ < 1.4 dB for an extinction ratio of ≥ 4.5 dB
or TDECQ < 1.3 dB for an extinction ratio of < 4.5 dB, the OMAouter (min) must exceed the
minimum value specified here.
3.Ceq is a coefficient defined in IEEE Std 802.3-2018 clause
121.8.5.3 which accounts for reference equalizer noise enhancement.
4. 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.
5.The receiver shall be able to tolerate, without damage,
continuous exposure to an optical input signal having this average power level.
6.Measured with conformance test signal at TP3 for the BER equal to
2.4x10-4.
7. These test conditions are for measuring stressed receiver
sensitivity. They are not characteristics of the receiver.
