Rack-Mounted 1 × N Multimode Optical Switch
1. Product Introduction
Optical switch is a kind of optical path control device, which plays the role of controlling and converting the optical path. And play an important role in optical communication application. The optical switch is mainly used in multi-channel optical monitoring, LAN multi-light source/detector automatic switching and optical sensing multi-point dynamic monitoring system in the optical transmission system, optical fiber, optical device, network and field engineering optical cable test in the optical test system; Optical device assembly and adjustment. The 1 × N optical switch can switch one input route to one of N output routes.
2. Product Features
Ø It has the characteristics of low insertion loss and fast switching speed.
Ø The LCD display screen is used to display data intuitively and facilitate the user's operation.
Ø Automatic scanning can be set, and the maximum switching interval is 99 hours, 59 minutes and 59 seconds; You can also set the Start Channel and End Channel of the scan.
Ø The "device address" can be set to facilitate the user to use one serial port to control multiple optical switch instruments in the case of shortage of serial port resources.

Schematic diagram of internal optical path of 1 × 24 optical switch
4.2.2. Description of Communication Interface Connection
(1) RS-232 interface
When connecting the device to a computer, you should use a serial port crossover cable with a hole DB9 at both ends. That is, the # 2 and # 3 pins at both ends are crossed and connected, the # 5 pins at both ends are butted, and the other pins may not be connected.
(2) RJ45 Ethernet interface
When the equipment is connected to the computer through the switch, the straight-through line should be used (the wiring sequence at both ends is: 1-orange white, 2-orange, 3-green white, 4-blue, 5-blue white, 6-green, 7-brown white, 8-brown); When the device is connected directly to the computer, a crossover wire should be used (one end: 1-Orange-White, 2-Orange, 3-Green-White, 4-Blue, 5-Blue-White, 6-Green, 7-Brown-White, 8-Brown; the other end: 1-Green-White, 2-Green, 3-Orange-White, 4-Blue, 5-Blue-White, 6-Orange, 7-Brown-White, 8-Brown).
