Production Description
The TSSDS-NAAEA1C is a Single-Channel, Pluggable, Fiber-Optic SFP28 for 25.78Gbps SR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78Gbps up to 70m using OM3 fiber and 100m using OM4.
This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector. The optical interface uses MDC receptacle.
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.
