Description

The 400GBASE-DR4 QSFP-DD is a 400Gb/s four-channel small form-factor pluggable double-density (QSFP-DD) optical transceiver that transmits data up to 2 kilometers over parallel single-mode fiber via a duplex LC connector. It converts eight 50Gb/s (PAM4) electrical input signals into four CWDM optical signals and multiplexes them into a single 400Gb/s optical transmission signal. Conversely, at the receiving end, the module optically demultiplexes the 400Gb/s optical input signal into four CWDM optical signals and converts them into eight 50Gb/s (PAM4) electrical output data signals. The four CWDM channels have center wavelengths of 1271 nm, 1291 nm, 1311 nm, and 1331 nm, and are primarily used for data center interconnects and 400G Ethernet applications. It complies with the IEEE 802.3bs standard, the 400GBASE-FR4 specification of the 100G Lambda MSA organization, and the 400GAUI-8/CEI-56G-VSR-PAM4 standard. The 400 Gigabit Ethernet signal is transmitted over four CWDM wavelengths. The multiplexing and demultiplexing of these four wavelengths are performed internally within the device.

Optical Specifications

Note 1:    Average launch power, each lane (min) is informative and not the principal indicator of signal strength.

Note 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 this value.

Note 3: Transmitter reflectance is defined looking into the transmitter.

Receiver Optical Specifications

Note 1: Average receive power, each lane (min) is informative and not the principal indicator of signal strength.

Note 2: Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with a value of SECQ up to 3.4 dB.

Note 3: Measured with conformance test signal at TP3 for the BER = 2.4x10-4
