optical module Mainly includes Optical electronic devices, functional circuits and optical interfaces, etc., is an important device in optical communication Now let fast fiber optics (feisu.com) I. Look at the demandIt's good to see. whether the requirements are met , such as clothes have many styles,
Maintenance Aspects 1
Each use of optical drive, the disc will inevitably strip into some dust, dust if falling to the laser emitter, will cause the optical drive to read the data difficult, affecting the quality and life of the laser head reading disk, but also affect the optical drive internal mechanical components of precision, so indoor must be kept clean, r
Restoration Technology is the most effective means for the mesh optical network to effectively cope with network faults and ensure service transmission in the network. Recovery techniques can be categorized and implemented in a variety of ways from different perspectives.
Link-level and channel-level
Based on the recovery granularity, optical network fault recovery can be divided into link-level recovery an
Optical Fiber Laser principles and characteristics
I. Introduction
Fiber Laser (Fiber Laser) is a device that uses glass Fiber reinforced with rare earth elements as the gain medium to produce Laser output. The fiber laser can be developed based on the fiber amplifier. Because the fiber core in the fiber laser is very small, the internal power density of the fiber is high under the pump, in this way, the laser energy level is "inverse of the number
One light flowThe concept of optical flow was first proposed by Gibson in 1950. It is the instantaneous velocity of the pixel motion of the space moving object in observing the imaging plane, it is to find out the correspondence between the previous frame and the current frame by using the change of the pixel in the image sequence and the correlation between the neighboring frames, so as to calculate the motion information of the object between the ad
For every computer enthusiast, we are very concerned about the read/write speed of the optical drive, especially when installing software. Changing the optical drive with better performance is our goal forever, but it is limited to embarrassment. Increasing the cache for the optical drive is an effective way to improve the read/write speed of the existing
At present, the optical fiber access network has been widely used in urban construction. So I have studied the principles and precautions for the construction of the urban optical fiber access network. I would like to share with you here and hope it will be useful to you. With the increasingly fierce competition in the communication industry, business development is also becoming more and more diversified,
Wiring skills-how to reduce the loss of Optical Fiber splices
Definition: a certain amount of loss occurs when the light is transmitted to the connector after the optical fiber connection is established.
Cause: the optical fiber fusion loss is mainly composed of the transmission loss of the optical fiber and the fusion
Wiring system in the link floor of the trunk, due to the number of small, currently widely used multimode quartz fiber, and in the horizontal direction, there is not a suitable medium can not only provide enough bandwidth, but also has both a convenient installation, low cost, strong anti-interference ability and so on. The new fiber-optic networks with plastic optical fibers (POF) have all the advantages. The diameter of the plastic fiber is generall
Computer startup in the "My Computer" to find the optical drive icon, naturally is not used, this fault is generally the optical drive driver is missing or damaged, optical drive interface bad, optical drive data line damage, optical drive jumper error, and so on.This failur
Photoelectric Mouse is a kind of hardware device that detects the displacement of mouse, converts the displacement signal into electric pulse signal, and then controls the movement of the cursor arrow on the screen by program processing and transformation. The photoelectric sensor of the photoelectric mouse replaces the traditional rolling ball. This type of sensor needs to be used in conjunction with a specially designed pad with a striped or dotted pattern. Mouse Research report shows:
Virtual optical drive Daemon tools using method
Although there are many kinds of virtual optical drive software, but they use the same method, first of all, the current mainstream elf virtual optical drive (Daemon Tools Lite) as an example to give you a brief introduction:
First, Software Installation

Because the USB signal of the computer is transmitted by cable, the communication distance is difficult to extend, generally not more than 30 meters. The scheme in this paper overcomes the shortcomings of USB signal short distance transmitted by existing cables, so as to provide a circuit for transmitting USB signal through optical fiber, so that the communication distance of USB is increased to several thousands of meters.
1. Implementation Principle
There are still many things worth learning about in the optical fiber access network. Here we mainly introduce the six features of Huawei's optical fiber access network. At present, the world's optical fiber copper withdrawal has become a trend in the Construction of optical fiber access networks. The FTTx-based
Three network integration of the innovative demand for optical access is mainly embodied in six aspects, one is the optical access system and its core chip, the second is an open intelligent integration of home network terminal equipment, three new fiber optic cable and OSP Line solutions, four is a new type of optical fiber access to key
