The intensity of the optical signal received by the optical receiving device needs to be within a certain range, and the optical power cannot be too strong or too weak, otherwise the life of the device will be shortened or it will not work normally. The optical fiber attenuator is an optical passive device that […]
Optical transceiver is the terminal equipment for optical signal transmission. We will inevitably encounter some problems during use. Next, the editor of Amini Technology will list some common problems encountered in the use of optical transceivers and the corresponding solutions in detail. Program, friends who are interested, let’s take a look! (1) What is the […]
The 100M optical fiber transceiver (also known as the 100M photoelectric converter) is a fast Ethernet converter. The optical fiber transceiver is fully compatible with IEEE802.3, IEEE802.3u, and IEEE802.1d standards. It supports three working modes: full duplex, half duplex, and adaptive. Gigabit optical fiber transceiver (also known as photoelectric converter) is a fast Ethernet, its […]
The performance of optical fiber connectors is first of all optical performance. In addition, the interchangeability, repeatability, tensile strength, temperature, and plug-in times of optical fiber connectors must also be considered. (1) Optical performance: The requirements for optical performance of optical fiber connectors are mainly the two most basic parameters of insertion loss and return […]
Recently, many people in the optical fiber industry chain have said frankly that the demand for 5G is not as good as expected. At the same time, LightCounting also pointed out in the latest report that 5G deployment is slowing, especially in the Chinese market. Do not have much hope for the return of 5G […]
The speed and capacity of information transmission are endless, and the growth momentum of the Internet is still unabated by 2020. High-bandwidth, low-cost optical module solutions have brought great convenience to network upgrades and new networks. The application of 40G optical module in Ethernet is realized through direct connection of optical fiber cable. OM3 and […]
Not long ago, Hubei Province held a science and technology conference. An exciting news from Wuhan Research Institute of Posts and Telecommunications, the laboratory of the Institute once again set the world record for optical transmission, reaching 400T per second. This means that an optical fiber with the thickness of a hair can accommodate 4.8 […]
C114 News on July 21 (Ace) A report from market research company Omdia shows that AT&T and Discovery have reached an agreement under which the two parties will merge WarnerMedia and Discovery and split the entity into an independent global entertainment company. The two companies expect the transaction to be completed in mid-2022. This transaction […]
When the optical cable is formed into a cable, there are two protection requirements for the optical fiber: one is that the optical fiber is less stressed; the other is that the optical fiber should be waterproof. The outermost layer of the optical cable is a plastic sheath, the inside is a metal sheath, and […]
