Description

Product Function

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.

Parameter	Description	Min.	Max.	Units	Comment
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.
