S-1110-S1SC10D-XT
Single Mode / Single Fiber
Connect copper ports over a single fiber strand ( also referred to as “Bi-Directional” BiDi )
When Single Strand fiber is used, a pair of Single Fiber Media Converters is needed for the copper to fiber conversion.
Perle Single Fiber Media Converters are also referred to as “Up/Down” models. For example the S-1110-S1SC10
U
-XT
(“Up”) and S-1110-S1SC10
D
-XT (“Down”), shown below, must be used in pairs. An “
U
p” must be matched with a “
D
own”
peer to deal with transmit and receive frequencies separately.
The majority of installations for single mode fiber media converters are of the “dual connector” or “dual fiber” type where
one fiber connection is used for transmit, the other for receive. These are physically “crossed” to match up the
Transmit/Receive links.
However, to reduce costs, or where there are limits on available fiber, WDM technology may be utilized. WDM uses
separate transmit and receive frequencies to communicate on a single fiber strand. WDM technology relies on the fact that
optical fibers can carry many wavelengths of light simultaneously without interaction between each wavelength. Thus, a
single fiber can carry many separate wavelength signals or channels simultaneously.
So remember, if Single Strand fiber is used, you will need an “
Up
” Media Converter on one side and a “
Down
” Media
Converter on the other for copper to fiber conversion.
Perle offers a wide variety of Single Fiber (“
U
p/
D
own”) Media Converters to connect 10BaseT, Fast Ethernet and Gigabit
to single fiber. Whether you need Managed or Unmanaged, Standalone or Modular Chassis Based, 20km or 120km, Perle
has the right model to meet your fiber conversion requirement.
