FW44L-5V-SM-0905-L/NL
The 4×4 mechanical optical switch is an optical path control device that serves to control and switch optical paths. The module maintains the optical path when power is off. It supports four optical signal inputs and can select four signal outputs or vice versa (bidirectional use). The module’s control method uses RS485 communication control. It plays a crucial role in optical communication applications. Optical switches are primarily used in optical transmission systems for multi-channel optical monitoring, automatic switching of multiple light sources/detectors in LANs, and dynamic monitoring of multiple points in optical sensing systems. They are also used in optical testing systems for fiber optic, optical component, network, and field engineering cable testing; as well as in the adjustment and alignment of optical components.

Description |
|
Set up the optical switch channel |
Command:<OSW_OUT_01_02_03_04 > |
The command sets the selection of optical switch channels IN1-OUT1, IN2-OUT2, IN3-OUT3, IN4-OUT4. A response of 1 indicates successful setup. If inputs XX and YY exceed the number of channels, a response of 2 is returned. A response of 3 indicates an issue with the optical switch. |
|
response1:<OSW_OUT_OK> response2:<OSW_OUT_OVERFLOW> response3:<OSW_OUT_FAULT> |
||
|
Check optical switch Current channel |
Command:<OSW_OUT_Magnet> |
The command indicates querying the current channel of the optical switch. A successful query returns a response indicating that the optical path is IN1-OUT1, IN2-OUT2, IN3-OUT3, IN4-OUT4. |
|
response:<OSW_OUT_01_02_03_04> |
||
|
Query optical switch information |
Command:<OSW_TYPE_Magnet> |
The command indicates querying information about the optical switch, and the response indicates the result.： Module model：OSW-4X4 operating wavelength：1260~1650nm Fiber optic types：9/125um Optical fiber protective tubing：0.9mm Fiber optic cable length：1m Control interface：RS-485 Connector：FC/APC |
|
response:<OSW_TYPE_ OSW-4X4_1260~1650_9/125_90_10_R4> |
Note: The module’s serial port baud rate is 9600, data bits are 8, stop bits are 1, and no parity is used. If an incorrect command is sent, the optical switch responds with <OSW_ERROR>
