multimode optical fibers transceiver is one of the optical transceiver, he shall go out through twisted-pair will electrical signal transmission, whether short or long, can through the transmission medium, the signal is converted to all "Unit "And, therefore, we can also call multimode optical fiber transceiver converter.As is known to all, if you use not within the scope of the network cable cover, the hairy optical transceiver is unable to use, so that, it is mainly used in the network environment, the network signal transceiver have certain effect.

multimode optical fiber transceiver

basic parameters which has RJ45 electricity and FC light mouth mouth, conforms to the standard 100 - base - FX, so the adaptive ability is very strong.In addition, it also has a full-duplex operation mode, which can prevent advertising storm, powerful data frames (1916 Bytes) to help it run fast.Because it has lightning protection circuit, so also don't have to worry about its damage in thunderstorm weather.Multimode optical fiber transceiver built-in twisted-pair a total of 2 km long, five times higher than single mode fiber optic transceivers.

installation method introduction 1, multimode optical fiber transceiver connected with web servers.2, to link it with hub, note that in the link, we use twisted pair of not more than 100 meters.3, with 100 base - TX equipment link, twisted-pair cable length is the same as the second point.In the process of connecting, fiber optic transceivers st street need connected to equipment of st interface, sc end interface with twisted pair of sc end interface connection.4, installation is successful.

multimode optical fiber transceiver transmission distance

as is known to all, if you use a different light, so the distance transmission by transceiver is also different.

1, multimode optical fiber transceiver: 2 km --5 km;

5, it is very convenient to maintain, and can be continuously upgrade, besides, it also provides a hot drawing frame type device plugged into the function.

6, it can be for network diagnosis, but also can at any time for a status report, abnormal network signal situation, it can be done in time control, and to provide users with the most complete the operation of the alarm log.

7, its working temperature range is not qualified, even if it is 20 degrees below zero to 40 degrees Celsius can be normal use.

8, power supply design "1 + 1 ", meet dangerous circumstance, it can automatic switching power supply to protect power rule.

single-mode and multimode optical fiber transceiver

a difference, the difference between single-mode and multimode optical fiber transceiver

according to the light in the optical fiber transmission mode can be divided into: single mode fiber and multimode fiber

um = 1 micron = 0.001 mm

multimode optical fiber in the fiber core diameter is 50 ~ 62.5 & mu;M, cladding outside diameter of 125 & mu;M, single-mode optical fiber in the fiber core diameter 8.3 & mu;M, cladding outside diameter of 125 & mu;M.The work of the fiber wavelength has a short wave length 0.85 & mu;M, long wavelength 1.31 & mu;M and 1.55 & mu;M.Fiber loss is generally decreases with longer wavelength, 0.85 & mu;M's loss of 2.5 dB/km, 2.5 & mu;M's loss of 0.35 dB/km, 0.35 & mu;M's loss of 0.20 dB/km, this is the lowest optical fiber loss, wavelength 1.65 & mu;M more than loss tends to increase.Due to the effect of absorption of the OH ˉ, 0.90 ~ 1.30 & mu;M and 1.34 ~ 1.52 & mu;M range are loss peak and scope of the two failed to make full use of.The 80 s, tend to use single mode fiber, and with long wavelength 1.31 first & mu;M.

multimode Fiber

multimode Fiber (Multi Mode Fiber) : center glass core coarser (50 or 62.5 & mu;M), can be a variety of patterns of light.But its mode dispersion is bigger, this limits the transmission of digital signal frequency, and with the increase of the distance will be more serious.For example: 600 MB/KM optical fiber in 2 KM, only 300 MB bandwidth.Therefore, the multimode optical fiber transmission distance is near, usually only a few kilometers.

single-mode Fiber

single-mode Fiber (Single Mode Fiber) : center core thin glass (core diameter is commonly 9 or 10 & mu;M), only the light of a pattern.Therefore, dispersion between the mould is very small, for remote communication, but there are material dispersion and waveguide dispersion, the single-mode fiber have higher request for the spectral width and stability of light source, the spectral width is narrow, the stability is better.Later found in the 1.31 & mu;M wavelength, single-mode optical fiber's material dispersion and waveguide dispersion is positive, negative, size also happens to be equal.This means that in the 1.31 & mu;Total m wavelength, single-mode fiber dispersion is zero.From the perspective of the loss characteristics of optical fiber, 1.31 & mu;M in just a low-loss optical window.In this way, 1.31 & mu;M wavelength region became a very ideal job window of optical fiber communication, and is now a practical optical fiber communication system of the main band.1.31 & mu;M conventional single-mode fiber is the main parameter by the international telecommunication union ITU - T determine in G652 advice, so this kind of fiber is also called G652 fiber.

single-mode and multimode technology is produced at the same time?Which is more advanced multimode is far from the more advanced first, general closer with multimode, only in single mode, because of the multimode optical fiber transceiver is much cheaper than single mode.

single-mode fiber used in long distance transmission, multimode optical fiber is used for indoor long-distance data transmission, can only use single mode, but the interior data transmission is not necessarily with a multimode.

servers and storage devices with optical fiber is a single mode or multimode mostly USES the multimode, because I just got the communication optical fiber is not too clear on this question.

fiber are to use, have to with a couple of single-hole single-mode optical fiber, such as signal converter equipment?To use

fiber would have with a couple of, yes, after half a problem you mean charge in a single fiber glowing?This is 1600 g fiber optic backbone network of China telecom is such.

single-mode fiber transceiver and multimode optical fiber transceiver the most fundamental difference is the transmission distance.Multimode optical fiber transceiver because it is in working mode is more nodes, port signal transmission, so the signal transmission distance is shorter, but is more convenient, excess in the construction of local Intranet.Single fiber is single node transmission, so is suitable for long distance trunk transmission across the metropolitan area network construction.On price, single mode than multimode expensive.

single mode optical fiber transceiver: transmission distance 20 km to 120 km 120 multimode optical fiber transceiver: transmission distance of 2 km to 5 km

single fiber optical transceiver: receiving data on a single fiber transmission:

pairs of fiber optical transceiver receive data on a pair of optical fiber transmission,

(2) how to distinguish between single-mode and multimode optical fiber transceiver

sometimes, we need to confirm the type of a fiber optic transceivers, so how to determine the optical transceiver is single mode or multimode?

below small make up teach you three ways to identify types of single multimode fiber optic transceivers.

1. From the bald head Remove the optical transceiver baldheaded dust cap See baldheaded interface device color inside, single-mode TX and RX interfaces inside painted with white ceramic., multimode interface are brown.

2. From the model to distinguish: generally see model in S and M, S for single mode, M said multimode.

3. If you have already installed, you can see the color of the fiber optic jumper, orange is multimode, yellow is single-mode

tip: single-mode transceiver can in single mode fiber and able to work under the multimode fiber, multimode optical fiber transceiver is can't work under the single mode fiber.The other is more than single mode switch equipment market.Can solve the single mode fiber and interchange of multimode fiber.

many small businesses and medium-sized enterprise network coverage area is very dense, so you need to multimode optical fiber transceiver, transmitting signals to help them quickly to achieve "Quick "The use of the network.The transceiver performance is very stable, whether hot summer or cold winter, transceiver signal will not be weather "Block ".Multimode optical fiber transceiver is suitable for application in telecom users and users of cable television.In addition, the biggest user is broadband campus network, it is definitely the most ideal campus network application equipment.
