Low Insertion Loss

Direct Voltage Drive

Compact design

How It Works

The design of the mems fiber optic switch is based on micro-electro-mechanical system. It normally uses optical micro mirror to change the direction of light beam to realize the switching of optical path. By changing the angle of the MEMS micro mirror driven by electric force, the input light can be switched to different output ends of the optical switch.

 

Discovering a range of custom optical assemblies, including 2-dimensional fiber array, linear fiber array, PM fiber devices, high-temperature optical components, and optical switch for coherent optical communication, sensing, biophotonics, and quantum communication. MEISU’s industry-leading pm fiber assemblies are designed for high-performance interferometric sensors, integrated optics and communications.

MFD Matched Linear Fiber Array

Regular 10um fibers can hardly been coupled efficiently when they are used to align with silicon waveguild. Therefore, fibers with small mode field diameter (MFD) come into use. It can be fusion spliced to SMF28 fiber, working as a connecting bridge between regular 10um fiber and silicon chip. MEISU's fiber MFD optical fiber array can be UHNA fiber spliced to regular sized SM fiber or PM fiber, keeping the splicing point as close as 7mm to the fiber array facet.

How It Works

MFD matched Fiber Array is assembled by fusing two types of fiber with different MFD (Mode Field Diameter) together, to realize optical transmission from ordinary single-mode fiber to small fiber mode field, polarization maintaining optical fiber to ordinary single mode fiber and single mode fiber to multimode optical fiber, etc.

 

MEISU's optical fiber components are being used in more and more fields far beyond traditional optical communication. We will never stop developing new optical devices to meet and lead the market trend, and we strive to come up with more solutions for our customers. From originally standard common SM fiber array for PLC Splitter to 2d fiber array with customized design for Astronomical Optics, from simply packed items to hermetia sealing and high-temperature survivable ones. Check out the listed five main applications, reach us with your needs. There are more solutions than you know here.

Micro Optical Switch

This kind of micro optical switch is driven by a relay to control the prism to turn, thus switch the path, with only few channels such as １ｘ１,１ｘ2, and２ｘ２. It is normally used for OLP (Optical Fiber Line Protection) system. This mini switch can be  

seen as an updated version of the regular mechanical optical micro switch in terms of the size of the case. Therefore, compared with the normal mechanical switches, it is more integratable.

 

Micro Optic Switch Feature

 

1x1, 1x2, 2x2 Bypass

 

Latching and Non-latching

 

IL: 0.7dB  

 

Switching speed: 4ms

 

Epoxy-free on the optical path

 

High isolation

 

Compact design

 

How It Works

Mini Mechanical Optical Switch is of the same structure of the normal mechanical optical switch, realized by using mechanical devices to move mirror or prism physically, thus to redirect optical signals to the desired output port. Whereas, mini type is more compact and easier to be integrated into customer's system.
