Product Overview
FW22FL-2-5V-SM-0905-L/NL
2X2 Full Pass-through Type, Single Mode 1310/1550nm, Latching/Non-latching, 5V, 0.9MM 0.5M Fiber, RS485 communication interface，135×60×20mm Box Module
FW22FL-2-SM-0905 is an optical path switching, conversion, and routing device that includes two channels of 2×2 optical switches, capable of performing direct and cross optical path switching for both groups. In fiber optic transmission systems, optical switches are used for multiple monitors, LANs, multiple light sources, detectors, and Ethernet protection conversions. Optical switches are primarily applied in: multi-channel optical monitoring in optical transmission systems, automatic switching between multiple light sources/detectors in LANs, and dynamic multi-point monitoring in optical sensing systems; fiber optic testing in optical test systems for fiber optics, optical components, networks, and field engineering optical cables; and the adjustment and alignment of optical components.

Description |
|
Set up the optical switch channel |
Command:<OSW_OUT_XX_YY > |
The command sets the selection of the optical switch channel. XX sets the first optical switch, and YY sets the second optical switch. When XX is 01, it switches to P1 connected to P3 and P2 connected to P4. When XX is 02, it switches to P1 connected to P4 and P2 connected to P3. A successful setting returns response 1. If XX exceeds the number of optical switch channels, it returns response 2. Response 3 indicates an optical switch switching failure or error. |
|
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 the response command, where XX and YY represent the current channel. 01: P1 is connected to P3, P2 is connected to P4 02: P1 is connected to P4, P2 is connected to P3 |
|
response:<OSW_OUT_XX_YY> |
||
|
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-2-2X2F-SM 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-2-2X2F-SM_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>
