The TSDR8-NAAMA1C is a 8-Channel, Pluggable, Fiber-Optic QSFP-DD for 400Gbps SR8 Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 53.125Gbps per lane up to 70m using OM3 fiber 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 76 contact edge type connector.
Absolute Maximum Rating
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.
