128GFC QSFP28 AOC GQS-MDO111-xxxC
The Gigalight Technologies GQS-MDO111-xxxC is a four-channel, pluggable, parallel, fiber-optic QSFP28 SR4 for 128G Fiber Channel and OTU4 applications. This active optical cable is a high-performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 112.2Gbps bandwidth. Each lane can operate at 28.05Gbps up to 70m using OM3 fiber or 100m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38-contact edge type connector. This module incorporates Gigalight Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
