Fibre Optic Splitters

Full Range of Splitters now in stock for overnight delivery.

Same as its name, fibre optic splitter is used to split a fibre optic beam into several beams at a certain splitting ratio. Fibre optic splitter is one of the key components in FTTH. Fibre optic splitter typical parameter include input and output part cable length, splitting ratio, working wavelength and with what kind of fibre optic connectors. Just like fibre patch cable, fibre splitters are usually with 0.9mm, 2mm or 3mm cables. 0.9mm outer diameter cable is mostly used in stainless steel tube package fibre optic splitters, while 2mm and 3mm cables are mostly used in box type package fibre splitters. Based on working wavelength difference there are single window and dual window fibre optic splitters. Typical connectors installed on the fibre optic splitters are FC or SC type or just tails for splicing.

Two technologies are common in the world of passive splitters: fused biconic taper and planar wave-guide splitters.

Fused Biconic Taper (FBT)

 

 

  • FBT splitters are made by fusing together two wrapped fibres.
  • Common production process.
  • Proven technology for OSP environments.
  • Monolithic devices are available up to 1 x 4 split ratio.
  • Split ratios greater than 1x4 are built by cascading 1 x 2, 1 x 3 or 1 x 4 splitters.
  • Split ratios from 1 x 2 up to 1 x 32 and higher (dual input possible as well).
  • Higher split ratios have typically higher IL (Insertion Loss) and lower uniformity compared with planar technology

 

Planar Splitter. (PLC)

  • optical paths are buried inside the silica chip
  • available from 1 x 4 to 1 x 32 split ratios and higher, dual input possible also
  • only symmetrical splitters available as standard devices
  • compact compared with FBT at higher split ratios (no cascading)
  • better insertion loss and uniformity at higher wavelengths compared with FBT over all bands
  • better for longer wavelength, broader spectrum

 

 

PLC SPLITTER: Operating wavelength, insertion loss, uniformity, return loss and polarization dependent loss, splitters performs superbly across temperature and wavelengths providing low insertion loss, low PDL, excellent uniformity and low return loss in configuration of 1 x 2, 1 x 4, 1 x 4, 1 x 16 and 1 x 32.

Mini Case PLC Splitters are a key component in FTTH and are responsible to distribute optical signals from input port to multiple outputs port.
