Our designs have been qualified and deployed in space applications and are widely used in terrestrial and submarine telecommunications systems.
MEMS OSW is based on micro-electro-mechanical system (MEMS) technology, which achieved low insertion loss and highly repeatability by rotating the mirror of MEMS chip.
MEMS OSW is mainly used in optical cross and connection (OXC) system, optical add/drop system, measure instrument system and optical signal monitoring system.
The products are Telcordia GR-1073-CORE qualified, and RoHS compliant.

Tsw | Optical switching time. During this period there may be invalid optical transmission on all channel | - | 40 | ms | - |
PWR-RDY | Power-up ready. The switch may lock up if TTL-level signals are applied to the data input | 200 | - | ms | SW must touch the OSW after power up for this time interval |
MCU-RST | A falling pulse will revert the switch to the default state | 500 | - | μs | - |
MCU-RDY | MCU reset ready begins from the rising edge of the reset pulse | 400 | 500 | ms | SW must provide time delay OSW reset and OSW channel select write |
Note: 1、Block function, the RESET PIN must be asserted to low level for at least 500us. And then go to high level. Define the maximum time of MCU_RDY as 500ms. After MCU_RDY, the OSW will be in BLOCK state. Maximum frequency of block is once per second. 2、TTL Mode means TTL parallel Mode, UART Mode means TTL UART Mode. 3、TTL Mode is retained by hardware, but not implemented in firmware. |
