Everyone should be familiar with fiber media converters, but to talk about what they are and what they do, you may not know clearly. Let’s take a look.


What is the fiber media converter


A fiber media converter is a network device that transparently converts Ethernet or other communication protocols from one cable type to another (usually copper CATx/UTP to fiber). They are usually used in pairs, with fiber segments inserted into the copper network to increase wiring distance and increase immunity to electromagnetic interference. People often use it to extend LANs, convert link speeds, and convert fiber optic modes.

Main types of fiber media converters


According to fiber properties

Single-mode fiber media converter: transmission distance from 20 kilometers to 120 kilometers;

Multimode fiber media converter: transmission distance from 2 kilometers to 5 kilometers.


For example, the transmit power of a 5km fiber media converter is generally between -20 and -14db, the receiving sensitivity is -30db, and a wavelength of 1310nm is used; while the transmit power of a 120km fiber media converter is mostly between -5 and 0dB, and the receiving sensitivity is between -5 and 0dB. is -38dB, using a wavelength of 1550nm.


According to the fiber required

Single-fiber media converter: the data received and sent is transmitted on one optical fiber;

Dual-fiber media converter: The data received and sent is transmitted on a pair of fibers.


According to work level/rate

100M Ethernet fiber media converter: work at the physical layer;

1000M Ethernet fiber media converter: work at the physical layer;

10/100M/1000M adaptive Ethernet media converter: work in the data link layer.


According to the work level/rate, it can be divided into single 10M, 100M fiber media converters, 10/100M adaptive fiber media converters, and 1000M fiber media converters. The single 10M and 100M media converters work at the physical layer, and the media converters that work at this layer forward data in bits. This forwarding method has the advantages of fast forwarding speed, high permeability, and low delay, and is suitable for use on links with fixed rates—better performance and stability.


According to structure

Desktop (stand-alone) fiber media converter: stand-alone client equipment;

Rack-type (modular) fiber media converter: installed in a 16-slot chassis, using a centralized power supply.


According to the structure, it can be divided into desktop (stand-alone) fiber media converters and rack-mounted fiber media converters. The desktop fiber media converter is suitable for a single user, such as the uplink of a single switch in the corridor. Rack-type (modular) fiber media converters are suitable for multi-user aggregation.


According to the management type

Unmanaged media converter: plug and play, set the working mode of the electrical port through the hardware DIP switch;

Managed media converter: Supports carrier-class network management.


Well, the above is the introduction of fiber media converters and their main types. If you have more questions, welcome to consult.
