Fixed connector
A fixed connector, also known as a fixed joint or a wiring sub, can combine two optical fiber end faces to achieve a permanent connection between optical fibers. The production methods of fixed joints include welding method, V-groove method, capillary method, casing method, etc. according to their working principles. Optical fiber fusion splicers are developing in two directions: one is to develop towards full automation and multi-function; the other is to develop towards miniaturization and simplification. At present, the commonly used fully automatic optical fiber fusion splicer equipment is cumbersome and expensive. In the future, this model will develop in the direction of improving accuracy, reducing costs, and especially increasing the number of connected cores. The development of small and ultra-small welding machines has become the second development direction. At the same time, it is committed to the research and production of multi-core optical fiber fusion splicers and polarization-maintaining optical fiber fusion splicers. Finally, in order to match the application of ribbon optical cable, multi-core fixed connectors should also be vigorously developed. fibconet.com
Optical attenuator
Optical attenuator is one of the earliest passive devices in optical communication. At present, four series of fixed, step-adjustable, continuously adjustable and intelligent optical attenuators have been formed. Currently, the market for optical attenuators is growing. Due to the low price and stable performance of fixed optical attenuators
Therefore, the market demand is larger than that of variable optical attenuators. The market demand for variable optical attenuators is still growing steadily due to their flexibility. At present, some foreign optical device companies are constantly developing various new optical attenuators in order to obtain practical products with higher performance, smaller size and more suitable price. From the perspective of market demand, optical attenuators will develop in the direction of miniaturization, serialization, and low prices. High return loss attenuator is an important direction of attenuator development. In addition, the optical attenuator must also have a wider temperature range and spectral range, and more excellent performance. fibconet.com
Optical wavelength division multiplexer
Optical wavelength division multiplexer (WDM), also known as optical multiplexer/demultiplexer, is an optical passive device that combines and separates optical wavelengths, and plays a key role in solving the expansion or multiplexing of optical cable lines. The currently used optical wavelength division multiplexers are mainly two-wavelength multiplexers. DWDM
With the development of multiplexing (DWDM) systems, the demand for multi-wavelength multiplexers is increasing, and the interval between multiplexing wavelengths is gradually shrinking. Therefore, densification, miniaturization, practicality, and componentization are the inevitable trends in the development of wavelength division multiplexers. fibconet.com
Passive optocouplers
The research, development and application of optocouplers have gone through nearly 40 years. At present, it has basically formed a situation in which fused taper-type devices are mainly used, and waveguide devices are gradually developed. With the rapid development of optical fiber communication, optical fiber sensing technology, optical fiber CATV, local area network, optical fiber user network and user access network, the demand for optical couplers will further increase. fibconet.com
