There are many types of fiber media converter, and their types change accordingly according to different classification methods:

Single mode/Multimode:

According to the nature of optical fiber, it can be divided into multi-mode fiber media converter and single-mode fiber media converter. Due to the different optical fibers used, the transmission distance of the media converter is different. The general transmission distance of multi-mode media converter is between 2km and 5km, while the coverage of single-mode media convertercan range from 20km to 120km;

Single fiber/Dual fiber :

According to the required optical fiber, it can be divided into single-fiber media converter: the data sent and received are transmitted on one optical fiber; dual-fiber media converter: the data received and sent is transmitted on a pair of optical fibers.

10/100/1000M:

According to the working level/rate, it can be divided into single 10M, 100M fiber media converters, 10/100M adaptive fiber media converters and 1000M fiber media converters . According to the structure, it can be divided into desktop (stand-alone) fiber media converters and rack-mounted fiber optic transceiversmedia converters. The desktop fiber media converter is suitable for a single user, such as meeting the uplink of a single switch in the corridor. Rack-mounted (modular) fiber media converters are suitable for the convergence of multiple users. For example, the central computer room of a community must meet the uplink of all switches in the community.

Management /Unmanagement:

According to network management, it can be divided into network management type fiber media converter and non-network management type fiber media converter.  According to the management type, it can be divided into non-network management Ethernet fiber media converters: plug and play, set the electrical port working mode through the hardware dial switch. Managed Ethernet fiber media converter: supports carrier-grade network management

Built-in Power Supply:

According to the type of power supply, it can be divided into built-in power fiber media converter: built-in switching power supply is a carrier-grade power supply; external power fiber media converter: external transformer power supplies are mostly used in civilian equipment. The advantage of the former is that it can support an ultra-wide power supply voltage, better realize voltage stabilization, filtering and equipment power protection, and reduce external failure points caused by mechanical contact; the advantage of the latter is that the equipment is small in size and cheap.

Full duplex/HaLf duplex:

According to the working mode, the full duplex mode (full duplex) means that when the sending and receiving of data are split by two different transmission lines, both parties in the communication can send and receive at the same time. This kind of transmission The mode is full-duplex, and the full-duplex mode does not need to switch the direction, so there is no time delay caused by the switching operation;

Half duplex refers to the use of the same transmission line for both receiving and sending. Although data can be transmitted in both directions, both parties in communication cannot send and receive data at the same time. This transmission method is half-duplex.

When the half-duplex mode is adopted, the transmitter and receiver at each end of the communication system are transferred to the communication line through the receiving/transmitting switch to switch the direction. Therefore, time delay will occur.

These are some basic common sense about fiber media converter. We can only be sure of the application when we have a basic understanding of fiber media converters, so as not to add trouble to the construction in progress.
