Description
ZK-QSFP56-200G-SR4 is a 4-Channel,Pluggable,Fiber-OpticQSFP56 for 200Gbps SR Applications.It is ahigh performance module for short-range data communication and interconnect applications which operate at 53.125Gbps per lane up to 70m using OM3fiber and 100m using OM4 fiber.The optical interface uses MPO receptacles.This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector.
Absolute Maximum Ratings
These values represent the damage threshold of the module.Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.
