Manufacturer s 100G Coherent Optical Module

100G optical modules, including QSFP28 and coherent transceivers, are available from leading manufacturers such as FS, NEC, EPS Global, Starview Technologies, and Precision OT, supporting high-speed 100Gb/s data transmission for data centers, enterprise, and metro networks.

Overview of 100G Optical Modules

100G optical modules are designed to provide high-performance connectivity for modern networks. The most common form factor is QSFP28, which supports 4x25Gb/s channels, enabling 100Gb/s aggregate throughput. These modules are widely used in data centers, enterprise core and distribution layers, and service provider networks .
