Optical fiber connector, mass interconnection and a high-speed signal type
In modern test equipment, as the test data throughput and data transmission distance increase, the use of optical fiber is inevitable.
Optical fiber can not only be used to transmit analog signals and digital signals, but also meet the needs of video transmission. Its data transmission rate can reach several thousand Mbps. If the repeater is not used, the transmission range can reach 6-8km.
The transmission mode of optical fiber transmission equipment can be simply divided into: multi-mode optical fiber transmission equipment and single-mode optical fiber transmission equipment.
Looking at the development of test wiring systems at home and abroad, three stages can be summarized:
1. Twisted pair stage: digital signal and analog signal can not be mixed;
2, coaxial cable twisted pair stage: relative twisted pair, bandwidth increase, can transmit audio and video signals, the maximum rate of up to 20Mbps;
3. Optical fiber stage: the transmission rate is greatly improved, different signal types can be mixed, and the commonly used multimode fiber can reach 1Gbps.
Multimode Fiber Optic Connector
The multimode optical fiber connector to be introduced today is a universal optical fiber connector launched by Tengfang Zhongke.
This optical fiber connector uses 62.5/125 multimode glass fiber with an insertion loss as low as -1.5db. It can transmit 300 meters at 850nm wavelength and 550 meters at 1300nm wavelength at 1 Gb/s rate, with a plug-in life of 5000 times.The specific parameter table is as follows:
This series of fiber optic connectors, including jack pin connectors, and with jumpers and adapter, the specific structure is as follows:
Let's take a look at the characteristics of this fiber optic connector:
01
The contact adopts elastic structure, and the insertion and extraction force is only 9.2N, which is convenient for on-off;
02
High plug life! Can guarantee at least 5000 times of plug;
03
Can be matched with a variety of adapter types, such as LC, FC, SC, SMA, ST, general various test instruments, convenient for customers to choose;
04
It can share the module with the existing coaxial/power pinhole, which is convenient to upgrade the test interface and match different signal types;
05
The minimum bending radius can reach 30mm, especially suitable for small spaces such as cabinets;
06
Allowable tension up to 100N, reduce the probability of fiber damage.
