Sobre Mí

 Passive optical networks are characterized by the 
"splitting" of the optical fiber one or more times 
in the field, resulting in the sharing of the optical fiber 
amongst multiple users. The fiber in a PON is typically 
shared with 16 to 32 users. Hence the bandwidth of the fiber 
originating at the CO/HE is shared among a group of users. 
The splitting of the network is accomplished by an optical 
splitter. These <a 
splitter/" target="_self">Optical Fiber Splitters can 
split the fiber 2 to 32 times and, by their nature, introduce 
inherently high losses in the network. Therefore, their use 
is limited due to the power budget consideration of the 


    The splitter has a great effect of increasing network 
reliability. A single 1 x 32 splitter has less loss than 1 x 
2 and 1 x 16 or 1 x 4 fiber splitter and 1 x8 cascaded 
splitters or any combination of 1 x 16 or fiber splitter 1 x 
4 and 1 x8 cascaded splitters in the network. With the 
evolution of optical networks, the need for multiple 
distributions of optical signals is crucial. For this 
application TELNET, S.A. offers its range of single mode and 
multimode fiber splitter. These couplers or splitters are 
used to split the input signal into N output branches with 
minimum loss.


    Functions of various fiber optic splitter types are

    PLC splitter is one of fiber optic splitter types, and 
just its full name is planar lightwave circuit splitter, and 
it is made of silica optical waveguide technology. It has a 
good channel to channel uniformity, high reliability and 
small size which ranges of wide operating wavelength. and is 
widely used in PON networks to realize optical signal power 
management. And We Fiberstore provide a series of 1 x N and 2 
x N splitters that all meet GR-1209-CORE and GR-1221-CORE and 
are certified by TLC for network development.


    Fused Fiber Splitter

    A fiber fused coupler is one of the most popular passive 
components for wavelength multi/demultiplexing or 
branching/combining of optical signal. They are used to split 
optical signals between two fibers, or to combine optical 
signals from two fibers into one fiber. Fused couplers do 
suffer from some disadvantage. Multimode fused couplers are 
mode dependent. Single fused couplers only transmit one mode, 
so they do not suffer from mode dependency. However, they are 
highly wavelength dependent. A difference in wavelength of 
which the fused fiber coupler will be used.


    FS fused fiber couplers are available in a range of 
wavelengths, fiber sizes, and splitting ratios. Standards 
configurations are one by two and two by two couplers. N by M 
couplers, such as one by three, or one by four and so on are 
also available on request.


    FTTH splitter

    As for another passive optical splitter, FTTH splitter, 
these couplers/splitters are very often used in CATV 
networks. The Plastic splitter box is used for fiber cable 
and fiber communication equipment connection. It has 
redundant space for pigtails and adapters after up to 48 
fusion splicing. FTTH splitter is suitable for the ABS or LGX 
packed splitters to protect the connection between fiber 
cable and pigtails, and mainly for FTTH projects to be wall 
mount or rack mount fiber splitter, which is realizing the 
function of fiber splitter, splicing, distribution and FTTH 
cable configuration. This kind of splitter always used 
together with a <a

    Except for these three types, there are some other 
splitters like <a
