Optical switches play an important role in optical networks, it can be used and the optical path converting optical switching network having one or more selectable transmission window, the optical signal can be mutually optical transmission line or an integrated light path conversion device or logical operations. MEMS-based optical switches are MEMS (micro-electro-mechanical system), using an optical microscope or an optical mirror array Wei beam propagation direction to change the optical path to achieve the switching.
MEMS optical switches can be widely applied to multicast switching optical switch (MCS), the optical cross-connects (OXC), the intelligent light distribution (iODF), an optical line monitoring (OLM), optical time-domain reflectometer (the OTDR) and optical fiber sensors, etc. field. Each wavelength 1XN optical switch can be switched to any of the N output ports, the switches can be used having a plurality of road / drop ports of an OADM (optical add / drop multiplexers) in. Each port carries one or more wavelengths.
Compared with the traditional mechanical type optical switch, the MEMS optical switch having small size, low polarization dependent loss, and high power consumption. Along with a low insertion loss optical switch is a mechanical, low crosstalk, low polarization sensitivity high switching speed, high extinction ratio and waveguide switches, small size, easy integration of large-scale benefits. It can be easily integrated into a high density optical communication system, and provides a fast switching speed, switching time ≤30ms. It may have the form of 1 × N multiple channels, such as 1 × 2,1 × 4 ~ 1 × 16.
MEMS optical switch can be used to achieve full remote control of all-optical network. Test point in the distal optical fiber, typically to a plurality of optical fibers connected to the OTDR (optical time-domain reflectometer), the switch to a different fiber to achieve monitoring of all optical paths through the 1 × N optical switch.
MEMS optical switch Applications: MCS (multicast switching optical switch) multicast-based PLC technology and MEMS technology switched optical switch (MCS), the next generation key part with the reconfigurable system (the ROADM) optical add-drop multiplex; each functional unit independent of M and N separate Splitter MEMS optical switch composition; provide N road (or drop) port is connected to the M direction.
iODF (Intelligent light distribution) cascaded integrated optical switch, can be used iODF (intelligent optical patch panel), instead of conventional private network MDF industry.
OXC (optical cross connect) cascaded integrated optical switch, can be used for small-scale OXC, to meet the needs of industry professionals critical path network and the data center.
TOF optical performance monitoring and OPM integrated or combined monitoring software, OPM by time division multiplexing, the signal monitoring performance multi-core fiber optical cable DWDM channels is widely used for monitoring optical transport network cable, the ROADM network, the DCI and the like.
Monitoring cable
and OTDR integration, combined monitoring software, by time division multiplexing OTDR, optical cable monitoring quality state of the multi-core optical fiber, widely used in PON networks monitoring cable, fiber optic cable monitoring optical transport network, the cable industry professionals network monitoring.
Optical fiber sensing sensor size of the market potential is large, the main products are 1x4 and 1x8.
Test instruments and test instrumentation factory automation and factory automation market is relatively small, but the high value, the optical switch of the optical performance, such as high insertion loss, return loss, repeatability requirements.
DWDM channel power equalization system, the node link power attenuation, light entering the optical receiver protection, light control quickly lead to off.
HYC independently developed products MEMS 1XN optical switch using the MEMS control chip and unique optical design, low power consumption, integrated, fast response speed, reduced costs, to customers more market. Not only to provide a range of MEMS optical switch device products, but also can be integrated with WDM, PLC or optical MEMS switch module and the PD module MCS.
