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".

A solid-state laser is one of the most common and reliable laser types used in modern industry, medical equipment, and scientific research. Unlike gas or fiber lasers, it uses solid materials as its gain medium to generate stable, high-brightness laser beams. Thanks to its high precision, long lifespan, and compact structure, solid-state lasers have become a mainstream solution for high-precision laser processing and optical systems.
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.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
