Optic Media Converters
American
Tech Supply carries Opterna's entire line of fiber optic media converters including
the 1100C fiber optic media converter line with ST, SC, MTRJ, and FJ connectors
available for several years and is being used in a wide variety of applications
in the industrial, educational, and military markets. These converters enable
designers to configure a “fiber to the wall” application without the
need to locate a fiber wall outlet near a power outlet. Power is supplied through
a “Y” cable that enables the converter to draw power from the computer
keyboard port. A version of the “Y” cable that enables the converter
to be powered from a Sun Workstation keyboard port is also available
American Tech Supply carries
a complete line of fiber optic media converters including a complete
line of hundreds of singlmode fiber optic media converter and multimode
fiber media converters including standalone media converters, rack
mount media converters, ethernet converters, ATM OC3 fiber converters,
T1/E1 Fiber Converters, DS3/E3 fiber converters from several manufacturers
and have most fiber media converters and fiber mode converters in
stock . We have one of the largest selections of fiber optic media
converters in the U.S.A. from leading manufacturers like MRV, Signamax,
Transition Networks and TC Communications and you will save with
our economical low cost line of fiber optic media converters.
Fiber Optic Media Converters
are devices that simply receive data signals from one media, convert
and transmit them to another other media. For example, media converters
can convert signals transmitted on a copper cable to signals that
run on fiber. Since Fiber Optic Media Converters function as physical
layer networking devices, they remain completely transparent to
other networking devices and any upper-level protocol.Media Converters
can function in either half-duplex or full duplex mode. Full duplex
Ethernet over UTP runs at 20 or 200Mbps, while half-duplex Ethernet
over UTP runs at either 10 or 100 Mbps. Full duplex Ethernet is
especially valuable in linking two switches or connecting a switch
to a file server. No adjustments are necessary when using either
mode. A Fiber Optic Media Converter will automatically sense which
mode is in operation.
   TC
Communications Fiber Optic Media Converters-
TC Fiber Media Converters - The TC3300R/S is typically used
to interconnect 10/100/1000Mbps switching hubs, workstations or
any other Ethernet, Fast Ethernet and Gigabit Ethernet compliant
device at distances up to 100km.
  Transition
Networks Fiber Optic Media Converters-Transition
Networks-10/100/1000 media converter that converts the electrical
signal of a 10/100/1000 Ethernet signal from copper to fiber. This
solution will offer a low-cost integration option for network managers
who want to migrate from 10/100 networks to Gigabit Ethernet. Gigabit
only switches can now be connected to 10/100 networks without the
need to upgrade the 10/100 side, allowing network managers to add
new equipment gradually. Fiber interface runs at 1000Base speeds,
which enables users to connect Gigabit ports on fiber switches.
Fiber connectivity options include SX optics and LX dual fiber with
distances up to 125km or single fiber up to 40km. In addition to
the standard 220 meters with standard SX optics, Transition Networks
also offers a proprietary solution that will allow users to transmit
up to 2km over multimode fiber (62.5/125µm) (xGFEB1024-100

utilizing lower cost 850nm optio-electronics, the 10/100BASE-SX
fiber optic media converter provides compatibility with legacy 10BASE-FL
devices while providing the lowest possible cost solution for fiber
installation of up to 60 meters (100BASE-SX). This makes it ideal
for building backbone and horizontal cabling applications where
cost and 10/100 auto-negotiation are critical.
  Signamax
Fiber Optic Media Converters-
Signamax-Signamax provides fiber optic media converter solutions
that support data, voice, video and image transport over a wide
variety of fiber optic and ethernet (other) transmission media.
These fiber optic media converters convert a wide variety of data
— from serial RS-232 through Standard, Fast, Gigabit Ethernet
and SONET/SDH protocols. Conversions from twisted-pair copper cable,
coaxial cable, multimode fiber and singlemode fiber, to other types
of cable are all possible with the wide array of solutions from
Signamax Connectivity Systems.
   The
MRV MC102 product line encompasses copper-to-fiber and fiber-to-fiber
conversion units. On all of these converters, the fiber port(s)
allow a choice of multimode or single mode fiber, single fiber operation,
different wavelengths and power levels. EM316xSF
- Single Fiber Media Converters MRV's Fiber Driver® family’s
Single Fiber modules use unique technologies, which provide the
ability to combine transmit (TX) and receive (RX) signals onto a
single fiber strand. This effectively doubles the available fiber
in a network, and eliminates the need for additional fiber installation.
The Fiber Driver Single Fiber modules employs Single wavelength
bi-directional technology in order to combine the TX and RX on the
single strand.
 IMC Fiber Optic Media Converter Converters- The rugged McBasic copper-to-fiber Media Converters support
all Ethernet protocols, making them ideal for all types of conversions
and network extensions inside or outside the LAN. The McBasic
series includes various cabling troubleshooting features such as
LinkLoss and FiberAlert, plus an internal power supply

 How
a fiber optic media converter works:
In recent years it has become apparent that fiber-optics are steadily
replacing copper wire as an appropriate means of communication signal
transmission. They span the long distances between local phone systems
as well as providing the backbone for many network systems. Other
system users include cable television services, university campuses,
office buildings, industrial plants, and electric utility companies.
This is an overview of fiber-optic technology, telecommunication
applications, fiber-optic advantages and disadvantages, and fiber-optic
economics.
A fiber-optic system is
similar to the copper wire system that fiber-optics is replacing.
The difference is that fiber-optics use light pulses to transmit
information down fiber lines instead of using electronic pulses
to transmit information down copper lines. Looking at the components
in a fiber-optic chain will give a better understanding of how the
system works in conjunction with wire based systems.
At one end of the system
is a transmitter. This is the place of origin for information coming
on to fiber-optic lines. The transmitter accepts coded electronic
pulse information coming from copper wire. It then processes and
translates that information into equivalently coded light pulses.
A light-emitting diode (LED) or an injection-laser diode (ILD) can
be used for generating the light pulses. Using a lens, the light
pulses are funneled into the fiber-optic medium where they transmit
themselves down the line.Light pulses move easily down the fiber-optic
line because of a principle known as total internal reflection.
"This principle of total internal reflection states that when the
angle of incidence exceeds a critical value, light cannot get out
of the glass; instead, the light bounces back in. When this principle
is applied to the construction of the fiber-optic strand, it is
possible to transmit information down fiber lines in the form of
light pulses.There are generally five elements that make up the
construction of a fiber-optic strand, or cable: the optic core,
optic cladding, a buffer material, a strength material and the outer
jacket (Fig. 1). The optic core is the light carrying element at
the center of the optical fiber. It is commonly made from a combination
of silica and germania. Surrounding the core is the optic cladding
made of pure silica . It is this combination that makes the principle
of total internal reflection possible. The difference in materials
used in the making of the core and the cladding creates an extremely
reflective surface at the point in which they interface. Light pulses
entering the fiber core reflect off the core/cladding interface
and thus remain within the core as they move down the line.
