Optical fiber In the erection, after the completion of the weld test work, the use of the instrument is mainly OTDR tester, with the Canadian EXFO ftb-100b portable Chinese color touch screen OTDR tester (Dynamic range of 32/31, 37.5/35, 40/38, 45/43db), you can test, The position of optical fiber breakpoint, the whole loss of optical fiber link, the loss distrib

In daily use, the core-level equipment of the Fiber Channel switch can play a very important role in the SAN storage process, which not only affects the network performance, fiber Channel switches provide Fiber Channel switching for high-bandwidth and Low-latency data communication. Currently, fiber channel switches pr

1. Mainstream Optical Network Technology 1. New Optical Fiber Technology The optical fiber production technology is now mature and is now in mass production. Today, single-mode optical fiber with zero dispersion wavelength λ 0 = 1.3 μm is widely used, the single-mode optical fiber with a zero-dispersion wavelength of λ

Study on the Influence of optical fiber nonlinear effects on optical OFDM signals (1) Optical Orthogonal Frequency Di-vision Multiplexing (O-OFDM) is a new type of Optical transmission technology that has been developed in recent years, it applies Orthogonal Fre-quency Division Multiplexing (OFDM) technology to optical fiber channels. Transmitting OFDM Signals in optical

What is a vswitch fiber port? What is the optical fiber port of a vswitch? What is the difference between a fiber-optic port of a vswitch and a common port? After reading this article, you will know a lot and hope you can learn more. Cascade uses both common ports and special MDI-II ports. A straight-through cable should be used when the two ports that are cascad

There are many broadband Internet access methods. For enterprises, ADSL and optical fiber are currently popular. The full name of ADSL is an asymmetric digital user line. It is a popular broadband Internet access method and a technology that provides broadband data services through copper telephone lines. Optical fiber is short for optical fiber. Optical

In various technical means to achieve broadband access, the optical fiber access network is the most suitable for future development solutions, especially the ATM Passive Optical Network (ATM-PON) it is almost an economical and effective way to integrate broadband access. Outside China, china Southern Bell, France Telecom, British Telecom, CNET, Japan NTT, Germany Telecom, KPN, SwissCom, SBC, Telecom Italia CSELT and other international institutions h

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.

Introduction In recent years, with the rapid development of Internet and information technology, people on the capacity of communication, transmission rate of higher requirements, now to the basic transmission of the physical layer of the media, in the information high-speed access to the electronic devices, resulting in the so-called "bottleneck", and as the network continues to extend, Anti-electromagnetic interference of the network in special place, anti-radiation, security and confidential

In the past two years, with the decrease in optical fiber costs and the wide application and upgrade of 1000Base and 10G Ethernet, optical fiber communication has gradually become an important part of LAN cabling and FTTx network construction. Due to the electromagnetic interference immunity of optical fibers, we do not need to consider the location Design of electromagnetic radiation devices such as power

The optical fiber access network is worth learning a lot. Here we mainly introduce the technical features of the optical fiber access network. The optical fiber access network refers to the access network with the optical fiber as the transmission medium in the access network. The Optical

Comparison of several types of Integrated Wiring and optical fiber cables What is indispensable in the process of Integrated Wiring is optical fiber cables.
