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

After using the computer for a long time, there will be some hardware began to aging, there are students have encountered a computer optical drive can not be out of the situation, click the Optical Drive button, see the optical drive light flashing two, can only hear the squeak sound, but the tray is not bounce, if more press a few disc racks can still bounce out

1. photoelectric signal conversion method For a long time, people have been using copper wires to transmit sound and information. However, more and more fiber cables have been used recently. Due to cost problems, we cannot replace all copper wires with optical fiber cables at once. However, to convert some cables into optical signals, the most important thing is to convert the electrical signals into

The Next Generation Network (NGN) is a hot topic in communication industry at present. As for the next generation optical network, taking SoftSwitch technology as the core, using high-capacity High density wavelength division system, large capacity optical switch with automatic configuration function, a new generation of optical routers, all kinds of low-end

1. Optical Fiber TypeSilica B1.1 single-mode optical fiber.2. operating wavelengthCapacity Indicators meeting the 13l0nm and 1550nm transmission windows3. Cut-off wavelengthThe λ c value tested on 2 m coated optical fiber is 1100cm ~ The λ cc value tested on 22 m fiber cables is less than or equal to 1270nm.4. Geometric PropertiesMold Field Diameter: nominal valu

The increasing requirements on network transmission capacity have promoted the further development of the 10 Gbit/s system. The IEEE Institute of Electrical and Electronics Engineers (IEEE) provides a description of the system configurations in LAN) and WAN in 802.3ae in terms of 10-bit Ethernet technical specifications.When the transmission speed of a Multimode system driven by an LED is 622 Mbit/s, the 10Git/s system can take full advantage of the cost-effective vertical resonator Surface Emit

China Telecom Shanghai (hereinafter referred to as Shanghai Telecom) disclosed its goal after broadband acceleration when it announced that it would start its fifth broadband acceleration this year, it is planned that the coverage of optical networks will increase by 1 million to 7.8 million, and the number of optical network users will increase by 1 million to 3.6 million. At the same time, Shanghai Teleco

Comprehensive analysis of the differences between optical fiber cables, network cables and cables In network hardware, another kind of media that can't be ignored is the network transmission media, which is usually called a network cable. Currently, common cables include thin twisted pair wires, optical fiber cables, coaxial cables, and coarse coaxial cables. 1. optic
