Singlemode-Multimode Fiber Optic Transceivers-Shenzhen Aixton cables co.,ltd

Single-mode fiber optic transceiver: transmission distance from 20 kilometers to 120 kilometers
Multimode fiber optic transceiver: transmission distance from 2km to 5km
For example, the transmit power of a 5-kilometer fiber optic transceiver is generally between -20 and -14db, the receiving sensitivity is -30db, and the wavelength of 1310nm is used; while the transmit power of a 120-kilometer fiber transceiver is mostly between -5 and 0dB, and the receiving sensitivity is between -5 and 0dB. is -38dB, using a wavelength of 1550nm.
required classification
Single Fiber Optical Transceiver: Receive and transmit data on one fiber
Dual Fiber Optical Transceivers: Receive and transmit data on a pair of fibers
As the name implies, single-fiber equipment can save half of the optical fiber, that is, data reception and transmission can be realized on one optical fiber, which is very suitable in places where optical fiber resources are scarce. This type of product adopts the technology of wavelength division multiplexing, and the wavelengths used are mostly 1310nm and 1550nm. However, since there is no unified international standard for single-fiber transceiver products, there may be incompatibility between products of different manufacturers when they are interconnected. In addition, due to the use of wavelength division multiplexing, single-fiber transceiver products generally have the characteristics of large signal attenuation.
Working level/rate
100M Ethernet Optical Transceiver: Working at the Physical Layer
10/100M Adaptive Ethernet Optical Transceiver: Working at the Data Link Layer
According to the working level/rate, it can be divided into single 10M, 100M fiber optic transceiver, 10/100M adaptive fiber optic transceiver and 1000M fiber optic transceiver and 10/100/1000 adaptive transceiver. The single 10M and 100M transceiver products work at the physical layer, and the transceiver products that work at this layer forward data in bits. This forwarding method has the advantages of fast forwarding speed, high permeability, low delay, etc., and is suitable for use on links with a fixed rate. At the same time, since such devices do not have an auto-negotiation process before normal communication, they are compatible with Better performance and stability.
