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 2x2 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.

RS-485 control command set

  •   “_”represents an underscore
  •  All letters in the communication protocol are uppercase.
  •  l This module can only execute one command at a time. Typically, you need to wait for the program to return a corresponding value before entering the next command.
  •   l In practice, use the less-than symbol “<” as the start marker and the greater-than symbol “>” as the end marker.

 

Name

Instruction

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_?>

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_?>

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>
