Understand the OFA: Optical Fiber Amplifier (OFA: Optical Fiber Amplifier) first understand the role of Optical amplifiers in Optical communications. In Fiber-optic communication, light causes loss and dispersion during transmission, which can weaken the signal over long distances. The traditional m

The first is the quality of the wire itself. For example, the wire is not up to standard. The copper core is made of copper clad aluminum or recycled，copper, while the standard twisted pair wire.The quality of the network cable has an impact on the speed of the network, because the material used in

For a zero-based population, the first encounter with communication is a very confusing one -- it's a huge concept, it feels like communication is all-knowing, but blind men and an elephant, i don't know what kind of existence it is. 2G/3G/4G/5g/WI-FI/Lora/NB-IOT/Bluetooth/NFC/Zigbee... ? ... We've

Cabinet is an indispensable part of electrical control equipment, is the electrical control equipment 'carrier' . As the carrier of the control system, the cabinet，plays a vital role in protecting the safety of the equipment. For outdoor cabinet equipment, its requirements are higher. Outdoor cabine

It is worth learning the customs declaration process, the steps are as follows: 1: Export Company staff contact customers pre-scheduled freight forwarding company, freight forwarding in advance and export staff consultation, the cost to be paid by the manufacturer (this cost is the price of the good

here are many professional terms in the field of industrial data communication, such as Ethernet, optical amplifier, protocol converter and so on. At the same time, there are many products in the field of industrial communication, such as industrial switches, industrial-grade fiber transceivers, fib

1. Low-loss optical fiber connectionTwo optical fibers often need to be connected to transmit light. For this purpose, the fiber ends must be very close together, the core must be perfectly aligned, and the fiber ends must be fixed to maintain alignment. The mechanical connector is equivalent to a s

1. how to choose cable?The choice of optical cable in addition to according to the number of fiber cores and fiber types, but also according to the use of optical cable environment to choose the structure of the optical cable and outer sheath.1) When outdoor optical cable is directly buried, loose a

There are many kinds of optical fiber, but for people who do not often use optical fiber, many specifications are really quite troubling. Sometimes, because they are not familiar with optical fiber specifications or are not clear about the wire required by the equipment, they will make the choice ve

Armored fiber patch cord, also known as steel armor fiber patch cords, are a special kind of fiber patch cords which are coated with a protective "armor" sleeve of spiral stainless steel. Armored fiber patch cord is a new type of optical fiber patch cord, which can be used in the machine room and in
