Supply Jinan fiber coupler, Evergreen Optocouplers

Fiber coupler (Coupler), also known as divergence device (Splitter), connectors, adapters, flanges, are used to implement the optical signal splitter / combiner, or for extending fiber link elements belonging to the field of optical passive components In telecommunications networks, cable television networks, subscriber loop system, the LAN will be applied to. Fiber coupler can be divided into standard coupler (belonging to the waveguide, dual branch, unit 1 × 2, that is, the light signal into two power), direct-attach coupler (connected to the same or different types of fiber optical interface 2 to extend fiber optic links), star / tree couplers and wavelength division multiplexer (WDM, if the wavelength is a high density separation, the wavelength spacing narrower belongs DWDM), production methods, there are sintered (Fuse), micro Optical (Micro Optics), an optical waveguide type (Wave Guide) three, and to methods for producing sintered majority (about 90%). Sintering methods make law, and together the two optical fibers is to burn melt tension, so that the core polymerization together to achieve light coupling, the most important production equipment is the fiber welding machine, which is an important step, although an important step by the machine OEM part, but after sintering, people still work detection package, so labor costs account for about 10 to 15%, furthermore using manual inspection package shall ensure the consistency of quality, and this is when mass production It must be overcome, but the technical difficulty is not as active components and optical DWDM module high, so early into the fiber industry manufacturers want, most will be cut from the optocoupler, gross profit in the 20 to 30%. According to different fiber coupling has the following classification: SC fiber optic coupler: SC fiber interface is applied, it is with RJ-45 interface looks very similar, but SC interface to appear more flat some, the obvious difference is the inside of the contacts, if 8 is thin copper contacts, it is RJ-45 port, if it is a copper cylinder is the SC fiber interface. LC fiber optic coupler: used LC fiber optic connector for connecting the connector SFP module, which uses easy operation made modular jack (RJ) latch mechanism. (Routers used) FC fiber optic coupler: used FC fiber optic interface, the external strengthening way is to use a metal sleeve, fastening means for the turnbuckle. Generally adopt ODF side (with the patch panel maximum) ST fiber optic coupler: used ST fiber interface, commonly used in fiber optic patch panels, rounded shell, fastening the turnbuckle. (For 10Base-F connections, usually ST type connectors commonly used in optical fiber distribution frame)
