pending image

 by www.fiber-mart.com When selecting optical modules, we should not only consider the stability and reliability of optical module functions, but also consider the price and quality, as well as whether they meet the requirements of network equipment compatibility and data transmission. Here, fiber-mart.com will introduce which optical module parameters should [ Continue reading…]


What are the differences between SM fiber and MM fiber?

pending image

 MM fiber Concept   MM fiber is a fiber that transmits multiple modes at a given working wavelength. When the geometric size of the fiber is much larger than the wavelength of the light wave, there will be dozens or even hundreds of propagation modes in the fiber. Different propagation [ Continue reading…]



How to test the optical power of optical transceiver?

In this article, fiber-mart.com will introduce to you, what is the difference between active optical cable(AOC) and direct attach cable(DAC)? First, the AOC is composed of integrated optoelectronic devices. The signal transmission process is that the A terminal module converts the electrical signal into an optical signal, the optical signal [ Continue reading…]


The way to choose DAC high-speed cable?

pending image

 DAC high-speed cable is a low-cost and short-distance connection solution for data center equipment. It consists of a cable and optical fiber transceiver devices at both ends of the cable. Because of the high cost performance, the interconnection application between short-distance network equipment is widely welcomed. At present, there are [ Continue reading…]


What are the key factors that affect the performance of DAC high-speed cables?

pending image

 The English translation of high-speed cable is Direct Attach Cable, or DAC for short. This article will introduce several key factors that affect the transmission performance of DAC high-speed cable. 1. Cable attenuation Cable attenuation refers to the reduction or loss of signal energy that occurs during the transmission of [ Continue reading…]


The advantages of OM5 optical fiber patch cord?

pending image

 1. Lower fiber loss OM5 is the name given to a new type of broadband multimode fiber, with attenuation reduced from 3.5 dB/km to 3.0 dB/km for previous OM3 and OM4 fibers, and additional bandwidth requirements at 953nm wavelengths. The geometry of OM5 (50μm core and 125μm cladding) is the [ Continue reading…]
