  The Difference Between Fiber Patch Cord and Fiber Pigtail F iber pigtails patch cords  are cables directly connected to desktop computers or devices to facilitate device connection and management. Patch cords have a thicker protective layer and are often used between terminal boxes and optical transceivers. Only one end of the pigtail has a connector. The other end is an optical fiber connector connected to other optical fiber cores in the form of fusion splicing and generally appears in the optical fiber terminal box.   Ⅰ. Specifications and types of fiber patch cords and pigtails Optical fiber patch cord is generally distinguished by single-mode and multi-mode in data transmission equipment. The color of the single-mode patch cord is usually yellow. There are two wavelengths, 1310nm, and 1550nm. The transmission distance is 10km and 40km, respectively; The color of the multi-mode patch cord is usually orange, aqua, magenta, etc. The wavelength is 850nm, and the transmission distanc

  1. What is fiber optical transceiver The 100g optical transceiver  is an optoelectronic device that performs electro-optical and photoelectric conversion. The fiber optical transceiver is a carrier, acting as the transmitting end to convert electrical signals into optical signals, and as the receiving end to convert the optical signals into electrical signals. Fiber optical transceivers can be divided into SFP, SFP+, XFP, QSFP+, QSFP28, QSFPDD according to the packaging form, and the types of optical interfaces include SC and LC. Fiber optical transceivers can be divided into 155M, 622M, 1.25G (1024M), 10G (10*1024M), 40G, 25G, 100g optical modules , 200G, 400G, etc. according to the transmission rate. The higher the transmission rate of the fiber optical transceiver is, the shorter the transmission distance. According to the transmission distance, it can be divided into short distance (2KM and below), medium distance (10 to 20KM), long distance (above 30 to 40KM), including 550M, 30

  Ⅰ. Learn about fiber Bragg grating sensors Fiber Bragg grating sensor can be used as a kind of fiber sensor. Like the optical fiber sensor, it has many irreplaceable advantages compared with the traditional electric sensor, such as: no electromagnetic interference, lightweight, small size, no corrosion, etc. Fiber Bragg grating sensors  are commonly used in structural deformation and temperature monitoring. Short-period fiber grating sensors are commonly used, and their reflection wavelengths are called Bragg wavelengths. Such sensors are called FBG sensors. Fiber Bragg grating sensor is a kind of fiber sensor with the highest frequency and the widest range, which includes FBG strain sensor, FBG temperature sensor, fiber Bragg grating pressure sensor, etc. This sensor can change the wavelength of the reflected light wave according to the environmental temperature and changes. Fiber bragg grating sensors use holographic interferometry or phase masking to expose a small section of ligh

  Direct cable is an ideal short-distance connection solution to replace optical transceivers. It can be divided into two categories: high-speed cable ( DAC   AOC ) and active optical cable (AOC). With cheap price, easy use and other advantages, it has been widely concerned by people. Now, with the wide use of 40G network, QSFP+ direct connection cable is also gradually popular. Now T&S will introduce the common QSFP+ direct cable solutions in the market in detail through this article.   40G QSFP+ AOC adopts optical cable as the transmission medium, which has the characteristics of lightweight and long transmission distance. In addition, there is also no need to worry about electromagnetic interference (EMI) when using an active cable.   1. 40G QSFP+ to QSFP+ AOC Like 40G QSFP+ to QSFP+ DAC, this active optical cable (AOC) is preterminated with two QSFP+ fiber transceivers at both ends. The transmission distance of our 40G AOC can reach more than 100m, but the price is higher than

  40G/100G AOC active optical cable has been globally introduced throughout the aoc data center  field. Compared to 40G DAC copper cable, 40G AOC active optical cable has unparalleled advantages in data transmission environment above 7 meters, including the smaller size, lighter weight, easier bending, easier management, longer signal transmission distance, etc. In the data center, the same goals can be achieved with a 40G SR4 optical transceiver. The differences between 40G AOC active optical cable and SR4 optical transceiver are analyzed as follows:   1. Insertion loss analysis of 40G AOC active optical cable and SR4 optical transceiver   With the same transmission distance, for SR4 optical transceiver, different optical fiber jumpers that are connected to the same module will produce different insertion loss and return loss, which is basically a common problem. However, as long as the variation is within the range, there will be no significant change in the eye map and other related
