Product Description

QSFP DD 400G LR4 SMF Fiber Optic Transceiver 10KM with FEC DDM Duplex LC

Description
Realsea 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.

Feature

ial interface for EEPROM signature which can be customized

* QSFP-DD MSA compliant

* 100G Lambda MSA 400G-LR4 Specification compliant* 4 CWDM lanes MUX/DEMUX design* 8x53.125Gb/s electrical interface (400GAUI-8)* Data Rate 106.25Gbps (PAM4) perchannel* Maximum power consumption 12W* Duplex LC connector* Operating case temperature: 0 to 70ºC* Up to 10km transmission on single mode fiber (SMF) with FEC* RoHS compliant

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.Products Compatible
