How to perform Optical Fiber fusion and testing?

How to perform Optical Fiber fusion and testing? 1. Optical Fiber Connection (1) optical fiber connection. The principle of optical fiber connection should be followed: when the number of cores is equal, it must be connected to the corresponding colored optical fiber in the

Basic knowledge of fiber optics

1) Type of fiberAccording to the transmission mode of optical fiber, it can be divided into multimode fiber (MMF) and single-mode fiber. The center glass core of multimode fiber is thicker (50 or 62.5μm), which can transmit various modes of light. But its modulus colors bulk, which restricts the transmission of digital

Method for Improving the precision of Variable Optical Fiber Delay Line

1 Introduction Nowadays, delay lines have been widely used in signal processing, radar, electronic countermeasure, and other fields. For example, the Unit delay device required for signal processing is a kind of memory, and the dynamic target display (MIT) there must be a delay line-another kind of memory. In electronic confrontation, the signal must be stored for a certain period of time before processing. For example, the receiver's radar signal must be delayed for a certain period of time be

Delphi to make GSM modem SMS sending control

At present, most enterprises and schools are built intranet. and built internal Web site to achieve resource sharing. In order to make users know the latest information on the Internet, many websites have adopted the way of SMS reminder, but using China Mobile or Chinese Unicom SP Way, will greatly increase the cost of the enterprise. Therefore, this article discusses the use of GSM modem and SMS send control to achieve SMS reminders. First of all, i

What about Win7 system modem errors?

What about Win7 system modem errors? The workaround is as follows: 1, the first need to check the power of each device and connectors are not plugged in. 2. Remote access Memo book files and current network and dial-up connections configurations may be inconsistent if you change your communication device, make sure that you reconfigure network and dial-up connections. If the error persists, you can delete and recreate network and dial-
