The structure of fiber optic patch cords
Usually the fiber patch cord is divided into single-mode fiber and multimode fiber, the Single mode optical fiber core diameter is small, only on work at a given wavelength in single mode transmission, transmission band, large transmission capacity,Among them, more widely used is the LC - LC Single Mode Patch Cord .
In the context of ontogenetic experiments with the rotary joint,a fiber optic patch cord is needed to connected the light source and the rotary joint and yet another patch cord to connect the rotary joint and the fiber optic annual
The core and the cladding are two layers that make up to the mark of the lightguide.However, the light travels inside the core of the fiber optic, barely or not inside the cladding.For this reason, interconnected fiber-optics should have the same core diameter.Different cladding diameters have no influence on the coupling efficiency.
The buffer is a protective layer that tightly encircles the cladding.For patch cords, we usually recommend for use of use of another protective layer, called jacket, which is a loose tube converting the previously mentioned layers of the cable.
For a better fiber protection,we also offer larger jackets made of pvc tubing ,In this case,we use the following color convention,or we can use the black jacket if preferred,Metal jackets or jackets made of other materials are also available on request.
Mono fiber optic patch cords.The simplest form of the patch cord is a member of fiber with buffer coating and two ferrules on its ends.So far, most popular fiber in ontogenetic research is a fiber with a 200μm core diameters and NA=0.22. The fiber diameter and its numerical limit the coupling efficiency into the fibre therefore for higher coupling from sources like LEDs into an optical fiber of a specific diameter, shift to a higher NA fiber and follow up all the way through to fiber optics cannula.
The zironia ferrules are preferred for becoming less expensive,of tighter tolerance,harder,mass produced etc.However,dure to the fluorecence of the zirconia ferrules they are not called for applications involving fluoresecence measurements.
Dual fiber optic patch cords.A dual fiber -optic patch cord has two fibres -optic strands within the jacket, where the fiber ends are inserted into the mono or dual fiber ferrules or connectors.
Some dual fiber patch cords were especially intended to be easily the light from the two optical channels of the 1x2 rotary joint into a dual fiber cannula. There are several types of dual fiber patch cords, being dependent on the type of connectors and cannulas used.
Branching fiebr-optic patch cords.Branching fiber patch cord consists of multiple single fiber patch cords that are at one end joined within one connector and its ferrule, while the loose side of the patch cords ends with mono fiber ferrules or connectors,
We offer fiber optic patch cors that branch from one input to N out put connectors,These patch cords have a single FC or SMA connector on bundled fiber end ,and an FC，SMA,M3,zirconia or metal ferrule for each fiber on the other end, If the source is an LED or a lamp,the optical power entering the fiber bundle is divided between the channels,In the case of a lease ,please refer to the Mini cube section.
In addition to the above introduction, and multimode fiber optic jumper, multimode optical fiber is working at a given wavelength, with multiple inheritance fiber model colleague, but compared with the single mode of multimode optical fiber transmission performance is poorer, multimode optical fiber has a variety of different interface classification, including LC LC Fiber Patch Cord which provide 10 gigabyte data transfer speeds in high bandwidth applications, and they are five times faster - than standard 50 um fiber cables. These aqua OM3 10g 50/125 fiber patch cables are with LC connectors at the ends of them, and they work with both VCSEL laser and LED sources, besides , LC-SC Patch Cord is very widely used In our daily life.
