PRODUCT PRESENTATION

The PHILISUN QSFP-DD 400G (4x100G) 1310nm 500m DR4 MPO8/12 Transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module, ideal for optical communication applications over distances of up to 500m. The module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 parallel optical signals, each supporting 100Gb/s, for a total data rate of 400Gb/s. On the receiver side, it reverses the process, converting 4 channels of 100Gb/s optical signals back into 8 channels of 50Gb/s (PAM4) electrical output.The module is compatible with MTP/MPO-12 connector optical fiber cables, ensuring precise alignment through guide pins inside the receptacle. To maintain proper channel-to-channel alignment, the cable should not be twisted. Electrical connectivity is achieved via an edge-type connector compliant with the QSFP-DD MSA standard.Designed with a compact form factor, robust optical and electrical connections, and a digital diagnostic interface, this transceiver is a reliable solution for high-speed, short-range data communication applications.

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.
