The single-mode gigabit optical fiber transceiver is an Ethernet transmission medium conversion device that exchanges electrical signals and optical signals of Ethernet. The optical fibers that transmit data on the network are divided into multi-mode optical fibers and single-mode optical fibers. The core diameter is 50-62.5 μm, the outer diameter of the cladding is 125 μm, and the core diameter of the corresponding single-mode fiber is 8.3 μm, and the outer diameter of the cladding is 125 μm.
Single Mode Gigabit Fiber Transceivers
But these data seem unimaginable, and there is a relatively simple way to distinguish single-mode fiber from multi-mode fiber is to look at the color. Generally speaking, the pigtail fiber of multimode pipeline is orange-red, and the color of the pigtail fiber of single-mode fiber is yellow.
From the perspective of networking applications, since multi-mode fiber cannot carry out long-distance transmission, it can generally only be used for networking within and between buildings. However, because the optical fiber transceiver corresponding to multi-mode fiber is relatively cheap, it is still within a certain range. has been applied.
1. Single-mode Gigabit fiber optic transceiver series
With the advancement of technology, single-mode fiber has begun to enter long-distance networking operations (from a few kilometers to more than 100 kilometers), and the development momentum is very rapid. In just a few years, it has entered the homes of ordinary people from high-end applications. From the current point of view, the use of optical fiber transceivers for networking has become a very common form of optoelectronics to carry out value-added services.
(1) Dual fiber single network port
The so-called dual-fiber single-network port optical fiber transceiver is a kind of use of two optical fibers (one receiving and one transmitting), and a group of optical fiber transceivers realizes the conversion of electrical signals to optical signals, and optical signals to electrical signals.
Single network port fiber optic transceiver
The network device here may be a switch or a server, so it is difficult to explain whether the network cable output by the fiber optic transceiver is a straight-through or a crossover cable. When the optical fiber transceiver is used as a PC, the connection between the PC and the switch is a straight-through cable, and the connection between the PC and the server is a cross-over cable, then the optical fiber transceiver and the switch are connected as a straight-through cable, and the connection with the server is a cross-over cable.
(2) Single fiber single network port
Two-way transceiver operation is realized on one optical core. This type of product adopts wavelength division multiplexing technology, and the wavelengths used are hidden at 1310nm and 1550nm, that is, one end uses light with a wavelength of 1310nm to represent transmission, and light of 1550nm represents reception; the other end uses The light of 1310nm represents the absorption, and the light of 1550nm represents the emission.
Single fiber single network port fiber optic transceiver
Generally speaking, if the optical fiber transceiver is placed in the computer room, we tend to choose this type of optical fiber transceiver. First, the quality of this structure is relatively stable, and second, these two modular structures can be replaced by placing the frame in the computer room. To achieve centralized placement of optical transceivers, for example, a 16-slot chassis can place 16 optical transceivers at a time.
This seemingly centralized device provides the conditions for us to use optical fiber transceivers to form a large-scale network. In fact, we use this frame-type optical fiber in the central computer room to form a network for local education, public security, banks and other units. transceiver.
(3) Single fiber dual network port
When we provide optical fiber networking requirements for units with stricter requirements, some units will require that the fiber optic transceiver equipment used is technologically mature, safe, and can be simplified, saving equipment investment, and realizing the use of a fiber optic connection. Enter two service networks with strict isolation and security requirements to save fiber resources to the greatest extent. The Ethernet electrical port of the device is a 10/100M self-adaptive port, the optical path can realize the access capability of the Ethernet link up to 60 kilometers, and supports the central office network management function. Under the network management platform, it can realize comprehensive monitoring and configuration of the central office equipment, as well as monitoring functions such as optical path receiving and sending two-way interruption alarms.
This networking structure actually forms a loop with the switch at both A and B. However, since the switch supports the spanning tree function, when a loop occurs, one route will be automatically selected as the working route, and the other route will be dropped. Disconnected as a backup, when the working line cannot work normally due to a fiber break on the line, the backup line will be automatically activated and become a working line.
