PM 1x2 Mechanical Optical Switch Mini Type
OPTICO's Mini 1×2 PM Relay-Type Optical Switch is a cutting-edge solution designed for high-precision optical signal routing in compact systems. This polarization-maintaining (PM) optical switch features a miniature form factor, making it ideal for applications requiring fast switching, low insertion loss, and high reliability. With its robust design and adherence to Telcordia GR-1221 and GR-1073 standards, it ensures consistent performance in demanding optical networks and instrumentation setups.
Working Principle
The Mini 1×2 PM Relay-Type Optical Switch utilizes an advanced relay mechanism to toggle optical paths between two states. This design ensures reliable polarization maintenance and stable signal transmission for critical optical applications.
State A
Connects port P1 to P2.
State B
Connects port P1 to P3.
