Most factory-made terminations are the epoxy/polish type. These provide the best performance and are a relatively inexpensive solution.
However, manual injection of epoxy is labor-intensive and requires skill to ensure proper bead placement. A dispensing system minimizes labor and improves epoxy fill control for higher quality results. The system also cures the epoxy in a curing oven to protect it from contamination and premature failure.
Patch Cords
The fiber optic patch cord is an important passive component of a fiber network. These cables connect the backbone or distribution cable to the work area. They can be jacketed or unjacketed and come in a variety of fiber counts. These can include simplex (1 fiber), duplex (2 fibers) and higher fiber counts such as MPO (12 fibers). They are also called Optical Splitters, Pigtails or Fiber Ties.
neofibo’s 353nd fiber optic epoxy glue is an ideal product for the manufacture of patch cords and pigtails. It can be used for both SM and MM applications, providing high reliability epoxy-glue-patch-cord-and-pigtail-manufacture-line-tools-and-machine and excellent adhesion. This epoxy is a two-part system that consists of resin and hardener. When combined in the correct ratio, they produce a rigid adhesive that is resistant to temperature extremes and provides good adhesion to metal surfaces.
These two-part epoxy systems are usually available as pre-measured tubes, making them easy to use. The separate components must be thoroughly mixed before applying. Some of these epoxy systems require a heat cure, which can be accelerated by adding heat or using UV light. These materials provide high strength, good corrosion resistance and exceptional chemical and environmental stability. They are also easy to clean up with water and can be used as a substitute for welding or rivets. They are also ideal for bonding plastics to metals.
Pigtails
Epoxy adhesives are one of the most versatile and adaptable industrial glues. They stick well to almost any surface and are highly resistant to physical and chemical influences. They can also withstand high temperatures and are easy to process and cure. In addition, they can be used with a wide variety of fillers. They can even be formulated to include marble dust, filite, metal powders, or dried ball clay to create high-quality putty.
When using epoxy, be sure to follow the instructions carefully. Most manufacturers recommend using a high-strength, two-part epoxy, such as RBTX-100C. These are used to make various telecommunications connectors, such as FC, SC, LC, MTRJ, and ST. Some companies use heat-cured epoxies when terminating fiber, but this method is not as quick or as portable as other methods.
Gluing metal is another common use of epoxy. It is ideal for repairing appliances, machinery, and pipes. It is also highly effective for securing bolts and screws to metal. A special type of epoxy that is designed for gluing metal can be purchased from specialty stores and is a good alternative to welding and soldering.
Compared to 2K epoxy, one component epoxy resin adhesives are easier to use because they do not require mixing. They usually have a paste-like consistency that makes them perfect for trowel application or extrusion by beads. They can also be cured at elevated temperatures between 120deg and 175deg C, depending on the formulation. They are ideal for applications that require a strong bond with high temperature resistance.
Connectors
Epoxy adhesives are extremely strong and bond very well to a wide range of materials. They can be sanded, drilled and painted after application. They can also be used as a gap filler and to re-bond materials that have been dislodged or broken. Epoxyes are often formulated to have a wide variety of useful qualities including chemical, temperature and abrasion resistance, water and environmental resistance, and conductive properties. Epoxy resins are available in one- or two- component systems and most come in a pre-mixed form that is dispensed through an injection syringe.
Almost every factory-terminated fiber connector uses heat-cured epoxy connectors because they provide the lowest loss, greatest reliability and highest yield of any termination type. In fact, it’s very easy for a trained technician to work with these connectors in the field and still get low losses and high yield. The key to success is using the right tools and techniques.
Most importantly, a technician should only use the best quality adhesive and know how to correctly inject it into the connector and cure it in an oven. It should take only a couple of minutes to terminate a single fiber with this method in the field, even when you have to prepare several cable ends at the same time, strip them and attach connectors. It is much faster than a hot-melt process and much less messy.
Termination
While some manufacturers demonstrate that it is possible to terminate one fiber in a minute or less using fusion splicers, they don’t usually take into account the time to set up and work on the job site, preparation of cable ends for termination and testing. This also includes cleaning Plastic Multimode Fiber Optic Components up the work area and repacking tools, fixing bad terminations, and preparing to start another job.
There are other types of connectors that don’t require glue and use a crimp to hold the fibre. These are known as “hot melt” or 3M trade name. These are pre-filled with the hot melt adhesive inside the connector and you strip the fibre, insert it in the connector, crimp it and put it in a special oven to cure for a few minutes. These are much faster to terminate but you’ll lose more optical power compared with epoxy type connectors.
Some epoxy resins can be made flexible by adding long-chain aliphatic epoxy compounds into the mix. This reduces the hardener component and makes it easier to manipulate the epoxy into a shape or position where needed, but it doesn’t affect the adhesive strength. This kind of flexibility is useful for coating Styrofoam or other insulative shapes, for laminating safety glass, absorbing vibration and sound, and encapsulating delicate electronic components that need to be exposed to temperature cycling.
