Bare / Fan Out / Mini Tube Fibre Optic Splitter With ASB BOX
Same as cable transmission system,optical network system also need signal coupling,branching and distribution,splitters can meet these functions.Splitter is the important device in PON transmission system,splitters can make the input optical signal into multiple output optical signal via splitting technology.There are two kinds of splitting technology: fused biconical taper(FBT type) and planar Lightwave Circuit type (PLC splitter type).In PON,all topology splitting products are with splitters,splitter is the basic devic for ODN topology splitting network in XPON access technology.
Based on unique silica glass waveguide technology and perfect fiber array coupling encapsulation,PLC splitters provide low cost,small size and high reliability splitting solutions.PLC splitters features:Low Insertion Loss,Low Polarization Dependent Loss,High Return Loss, Excellent uniformity in the wavelength range of 1260-1650nm, Wide Operating Temperature: -40°C - 85°C.
Fiber optic splitter features small size, high reliability, wide operating wavelength range and good channel-to-channel uniformity, and is widely used in PON networks to realize optical signal power splitting.
1. Bare fiber Type Splitter
Bare fiber Type Splitter adopts minimal encapsulation structure,after encapsuling PLC chips in metal box directly output the bare fiber,small and compact size,mainly used for subsequent modular encapsulation or put in other function modules and directly splice(for example put into splice closure)
2. Fan out Type splitter
Branching Type splitter adopts minimal encapsulation structure,after encapsuling PLC chips in metal box directly output the fiber, small and compact size, with bunch fiber inputs and ribbon fiber outputs,transfter into bunch fiber outputs via splitters.The inputs and outputs of this kind of splitter can provide connector plugs,can use it directly,suitable for compact size application(such as slot box and wall-mounted box)
3. Mini tube type splitter
Mini tube type splitter with compact encapsulation box,it can realize φ0.9mm loose tube fiber multiple outputs directly without fan out,it’s not only remain the advantage of compact structure but also can directly outputφ0.9mm pigtails,it’s the ideal option for small size application.
4. Module(ASB BOX) Type Splitter
Module(ASB BOX) Type Splitter adopts standard module encapsulation box,it can realize different diameter pigtails(φ0.9mm, φ2.0mm, φ3.0mm)output,in the meantime,PLC device encapsulate in the box.It has the highest protection grade and less demand on placing position and environment.Widely used in slot boxes and wall-mounted boxes.
