GIGALIGHT 400G QSFP56 DD SR8 Active Optical Cable
The GIGALIGHT Technologies GQD-MDO401-xxxC is an eight-channel, pluggable, parallel, fiber-optic QSFP Double Density for 2x200 Gigabit Ethernet applications. This AOC is a high-performance module for short-range multi-lane data communication and interconnect applications. It integrates eight data lanes in each direction with 8x26.5625GBd. Each lane can operate at 53.125Gbps up to 70m using OM3 fiber or 100m using OM4 fiber with FEC. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 76-contact edge type connector. The Common Management Interface Specification (CMIS) for QSFP DD modules, combined with GIGALIGHT Technologies' proven circuit and VCSEL technology, provides reliable long life, high performance, and consistent service.

Product Model: QSFP28 host board V1.30 PCB Marking: E206460 PCB Number: AL-85MA-0
QSFP28 Host Board V1.30 is a high-speed host-side evaluation/test PCB for 100G QSFP28 optical transceivers. The board routes the QSFP28 electrical interface to an arc array of gold SMA coaxial connectors around the top edge and to a QSFP28 cage/connector at the bottom center, enabling signal-integrity, compliance and interoperability testing of QSFP28 modules on the host side. PCB markings include E206460, AL-85MA-0 and the revision label "QSFP28 host board V1.30".

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
An infrared transmitter (IR transmitter) is a basic electronic component that sends invisible infrared light signals for short-range wireless control. It is widely used in daily electronics, smart home devices, and industrial equipment due to its low cost, low power consumption, and stable performance.
