Optical fiber connector structure

Optical fiber connector is designed to achieve fiber channel connection, which is widely used in optic fiber communication systems, with various types and structures, but basic structure of various type optical connectors is same, most fiber optic connector are using high precision components for fiber optic connection implementations, high precision component is composed by 2 pins and 1 coupling tube.

Penetrating and fixing fiber optic into pins, then polish pin surface, alignment is achieved in coupling tube.

Outer component material is metal and non metallic material.

Surface grinding treatment is needed for pins mating interface.

Coupling tube common material is ceramic and bronze, etc, which is consisted of two half cylinders.

Most fiber optic connectors are with metal or plastic flange for fixing function.

To improve the alignment of fiber optic, the precision requirement of pins and coupling tube shall be increased.

Electric connector manufacturer--sunkye

Connector is an indispensable part of electronic device, when you observing electrical connection, you will find one or more connectors. Electric connector form and structure is ever-changing, different connector form depends on application, frequency, power and environment, etc. For example, connectors for lights and hardware driver are totally different from connector for rocket.

Centrical connector is the mini size connector, also with switch function; application is low frequency circuit, such as earphone, microphone, and power supply.

Strip connector, which is soldered on printed circuit board, reliable connection, easy to us, applied for connection of electric instruments.

Circular connector, screw coupling mechanism is very common, small size, high reliability, can meet the requirement of electronic device connection.

Rectangular connector, with locking component and design, main application is electronic devices, intelligent instruments and electronic control units, etc.

Waterproof sealing connector, which can be applied in water and other harsh environment.

RF coaxial connector is the small type screw coupling mechanism connector, small, light and easy to use, suitable for wireless electronic devices, high frequency circuit connection in electronic instruments, etc. Working frequency is about 500MHz.

military,medical,industrial Connector plating material

military,medical,industrial Connector plating on connectors can ensure connection performance and avoid corrosion, oxidation, etc, especially in harsh environment, military connectors, aerospace connectors and also industrial and medical connectors.

Below is plating material details:

Tin (Sn)

Tin plating type is pre-electroplating, pre-cladding, plating. Tin is soft and anti-corrosion with cheap price. Easy to solder, common thickness is 2~4mm, matte or glossy silvery.

Gold (Au)

The best advantage of gold plating is very soft material, anti-corrosion, insoluble in pure acid, good electroconductivity, but very expensive. So elective gold plating is very popular. Gold plated over nickel, common thickness 0.4~3.5mm.

Palladium (Pd)

Palladium can be applied instead of gold plating sometimes.

Nickel (Ni)

Silvery, electroconductivity and weldability is not good, after painted, it is hard and smooth, can be applied for base plating before gold plating.

Silver (Ag)

Gloss white, soft, good electroconductivity and weldability, but very expensive and silver tarnish quickly.

Copper (Cu)

Material electric data:

Material   electrical conductivity    resistivity   specific gravity   melting temperature

Connector development trend is miniature, lighter

Unmanned systems, military and commercial avionics systems and welding to install applications require a power and data connector, lighter, smaller, but entrenched military specifications before don't account for the reduced size and weight requirements especially for circular connector connection standard electronic box box or other military equipment.

These military mil specification circular connector to withstand the shock and vibration, salt spray, dust and dirt, and water and humidity, however, a growing number of them is too big, some military smallest platform.

Aviation electronics connector business see system, they see is the big, military circular connector, weigh a lot, military and aerospace applications, quality.
"The military ability of circular connector is really shocked and atmosphere, but you are using too much weight and real estate, in the end who will have to be replaced, you need to design to military standard mil, but how do you change the mil standard?"

Adhesive to the latest generation of unmanned aerial vehicle (uav) as prime example, today's military connector applications, promoting the development of electronic and optical connector technology.

The Development of Circular Connector

When the connector market develops synchronously with the world economy,

the connector varies rapidly as well, as for the circular connector, it has been developing to nano circular connector.

The nano circular connector fitted pins and socket with contacting spacing of 0.025” can use 4 times of interconnection devices in the same circular area. The new circuit requires current less than 1A, as the digital processing makes the cable assemblies adopt the smaller cable to accommodate the nano circular connector, therefore the weight and diameter of interconnection network system reduce greatly.

The waterproof circular connector has also been concern by many customers, compared with the general circular connector, waterproof circular connector has following characteristics,

1. Quick connection, the minimum lock rotation, per 1/8 turn can save wiring time and effort greatly.

2. Clicking feeling, click sound will be heard when connection locked and feed back

3. Backward compatible, it can match the standard spiral M12 connector

4. The same protection standard, conform to IP67 requirements.

Huber + Suhner New Connector Double the Optical Fiber Density

Swiss company Huber + Suhner AG says its new LC-XD opticalfiber connector doubles the optical fiber density, and improves the optical fiber operation of the central office and data center. In London FTTH conference of 2013, the new connectors designed and launched by Huber + Suhner can reduce the space significantly, and is helpful to control cost and improve performance.


LC-XD optical fiber connectors have single and double (iniboot) version, can operate 4,032 pcs of optical fiber in a rack, which is twice the density of previous d device processing, the connector is equipped with a rigid and progressive leverage with special push-in mechanism, while allowing greater density and more efficient operation, and supporting vertical space and manual access for installation and ongoing operation.

The LC-XD single edition is dedicated to FTTH network, that is the single optical fiber which meets the household requirement, the connector can be connected in both directions and can be inserted and extracted even in the case of indirect contact. The LC-XD uniboot edition is mainly applied to data center, the connector can inverse polarity without additional tools.

The LC-XD connector is compatible standard adapter, mini LC adapters and optical transceivers are compatible.
