PRODUCT PRESENTATION

The PHILISUN QSFP-DD 400G (4x100G) 1310nm 10km LR4 LC DX Transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-Double Density (QSFP-DD) optical module designed for optical communication over distances up to 10km. This module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 CWDM optical signals, multiplexing them into a single channel for 400Gb/s optical transmission. On the receiver side, it de-multiplexes the 400Gb/s optical input into 4 CWDM optical signals and converts them back into 8 channels of 50Gb/s (PAM4) electrical output.The 4 CWDM channels have central wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm, as defined by the CWDM wavelength grid in ITU-T G.694.2. The transceiver features a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To ensure optimal performance over long distances, single-mode fiber (SMF) must be used.Additionally, host Forward Error Correction (FEC) is required to support transmission distances of up to 10km.This module is designed for reliability and efficiency, making it an ideal solution for high-speed, long-range optical communication in advanced network systems.

PERFORMANCE PARAMETER

Absolute Maximum Ratings
Parameter	Symbol	Min.	Max.	Unit
Power supply voltage	VCC	-0.5	+3.6	V
Storage temperature	TC	-40	+85	°C
Relative humidity	RH	0	85	%
These values represent the damage threshold of the module.Stress in excess of any of theindividual absolute maximum ratings can cause immediate catastrophic damage to the module even if all other parameters are within recommended operating conditions.
