Fiber Media Converter - What's the Use and How to Choose It
By Colin Yao
What are fiber media converters?
Fiber media converters are used to convert electrical signal to light signal and vice
versa. They are basically used as network extenders to extend the distance from
several hundreds of feet to several thousands meters. They are perfect for linking
networks between campus buildings.
The electrical signal can come from thick coax cable, UTP cable, and STP cable, etc.
The light signal can be carried via single mode fibre and multimode fibre depending
on your distance requirement.
What types of fiber media converters are available?
1. 10BaseT, 100BaseT, 1000BaseT Ethernet to Fiber Converter
Fiber media converters are used to connect multiple LANs to form a large campus
area network. At the most, they can extend the reach of LAN over single mode
fiber up to 130km.
Other UTP-to-fiber converters have redundant link functions. They not only extend
the network over fiber, they can also switch communications to a backup link
automatically if the primary link is broken.
2. T1 / E1 to Fiber Converter
T1 / E1 fiber media converters are available to provide T1 / E1 copper to fiber conversio
to extend T1 fiber distances up to 100km. They support AMI or B8ZS / HDB3 modes
and have a RJ45 / RJ48 port. They can support both multimode and single mode fibers.
3. Serial Copper to Fiber Converter
Serial to fibre converters support X.21, RS-530, RS-232, RS-422, RS-485 applications
featuring several configuration modes to enable connections with a wide variety of devices.
They transmit serial protocol over fibre. Some even have remove fibre loop-back switch
for testing of fibre link, even during serial transmission.
4. Fiber Mode Converter
Fiber mode converter converts from single mode fibre to multimode fibre and vice
versa. It provides transparent conversion between these devices. This converter
regenerates signal from multimode fiber and is used to extend the distance up to
tens of kilometers via single mode fiber.
5. Media Converter Chassis
If you only need to convert between two systems, such as from 1000BaseT to fiber,
a stand alone fiber media converter is enough. However, if you need to convert many
cable types, then you probably would want a converter chassis. The chassis houses
everything in one place. They even provide internal power supplies.
