PRODUCT PRESENTATION

The PHILISUN QSFP28 100G 850nm 100m SR4 MPO 8/12 Transceiver is a high-performance, highly integrated 4x25G module designed to optimize reach, bandwidth, density, and cost for high port-count 100G systems and client-side 100G interfaces. Each lane supports data rates of 25Gbps, enabling transmission distances of up to 70m over OM3 fiber or 100m over OM4 fiber.Engineered for multimode fiber systems, this transceiver operates at a nominal wavelength of 850nm. It features a 38-contact edge-type electrical connector and a 8/12-fiber MPO optical interface for seamless integration into high-speed network environments.

PERFORMANCE PARAMETER

Absolute Maximum Ratings
Parameter	Symbol	Min.	Max.	Unit
Power supply voltage	VCC	-0.5	+3.6	V
Storage temperature	TC	-40	+85	℃
Relative humidity	RH	5	85	%
These values represent the damage threshold of the module.Stress in excess of any of the individual absolute maximum ratingscan cause immediate catastrophic damage to the module even if all other parameters are within recommended operating conditions.
