FSW-1U-1X10-MM-FCPC

The FSW-1U-1X10-MM-FCPC is a high‑performance optical path control device designed for reliable signal routing in rack‑based communication systems. It features low insertion loss (≤1.2 dB), fast switching time (≤10 ms), and high channel isolation (≥35 dB), ensuring stable operation across the 850 nm wavelength range. Equipped with an intuitive LCD display and supporting both manual control and programmable operation via RS‑232 or Ethernet interfaces, this switch is ideal for multi‑channel optical monitoring, LAN source/detector switching, and optical test systems. Housed in a standard 19‑inch 1U chassis, it offers flexible integration for data centers, labs, and industrial applications.

Description

Product Overview

An optical switch is an optical path control component that functions to control and switch optical paths. It plays a crucial role in optical communication applications. Optical switches are mainly used in:
  • Multi-channel optical monitoring in optical transmission systems, automatic switching of multi-light sources/detectors in LANs, and multi-point dynamic monitoring systems for optical sensors;
  • Testing of optical fibers, optical components, networks, and field engineering optical cables in optical testing systems;
  • Assembly and adjustment of optical components.
A 1×8 optical switch can route one input path to one of the 8 output paths.

Product Features

  • Low insertion loss and fast switching speed.
  • Equipped with an LCD display for intuitive data presentation, facilitating user operation.
  • Automatic scanning can be set, with a maximum switching interval of 99 hours, 59 minutes, and 59 seconds; the “start channel” and “end channel” for scanning can also be configured.
  • A “device address” can be set, allowing users to control multiple optical switch instruments with a single serial port when serial port resources are limited.
  • The serial port communication baud rate can be adjusted according to actual needs, with 7 optional baud rates: 1200, 2400, 4800, 9600, 19200, 57600, and 115200.

Program-Controlled Commands

(1) The instrument executes only one command at a time. Wait for the program to return a response before entering the next command.

(2) Use uppercase letters for commands.

(3) In actual operation, use “<” as the start character and “>” as the end character.
