1×2 POF – Splitter standard
The 1×2 standard POF splitter has low excess loss. It is preferred for system applications that don’t require high crosstalk attenuation, e.g. in illumination or optical powersplitting in sensor systems. The 1×2 standard POF splitter comes with 3 alignment ferrules that are crimped to standard 1mm POF with 2.2mm jacket. Slight pressure to the ferrule fixes the cable.
Minimum order quantity of 1 x 2 POF Splitter, standard, splitter is 5 units.
1 x 2 POF Splitter Low Crosstalk
Optically coated splitter blanks are used to fabricate the 1×2 Low Crosstalk splitter. Light coupled to a splitter branch should not, or with high attenuation only, to the other splitter branch. High crosstalk attenuation is important for data transmission and sensor systems that use the splitter to combine an LED transmitter with a receiver PIN diode. In this way crosstalk from transmitter to receiver is avoided.
The 1×2 Low crosstalk POF splitter comes with a plastic ferrule at the splitter tip. A 1mm standard POF with 2.2mm jacket is fixed via a lock nut adapter screw. Due to our fabrication process 1×2 POF splitter come with a splitter branch length of about 60mm. The maximum splitter branch length is limited to 120mm.
1×2 POF-Splitter with long fiber pigtails
For applications in which the usual length of 60 or 120 mm are not sufficient, a special manufacturing process can be used to fabricate POF-Splitter with arbitrarily long splitter branch lengths. The POF-Splitter itself is protected by metal tube. The connections to 1mm POF cables are made with drew adjustments ferrules. The excess loss is higher than the standard splitter because the insertion loss of 4m well polished POF cable is in the order of 2.5 to 3 dB.
1 x 2 V-pin POF – Splitter
The 1 x 2 V-pin POF splitter is used advantageously when it is used in a system with V-pin connectors. By using a plugged-in POF cable with V-pin connector it can be used a splitter with long splitter arms. The 1 x 2 V-pin POF Splitter has no low crosstalk characteristics. On request, the splitter arms can be made in any desired length and connectors of different types (e.g. V-pin, FSMA, SC) can be attached to the fiber ends.
Examples for 1×2 POF splitter with a customer specific connector and interface design:
Unsymmetric 1×2 POF-Splitter
Asymmetric polishing of splitter blanks allows the fabrication of 1×2 splitter with a splitting ratio of 67/33 or 75/25. Asymmetric splitters are applied for the monitoring optical signals with an attenuation as low as possible. Due to mechanical stability reasons splitting ratios of 90/10 are not feasible.
