J599E6 series beam expansion type high-density optical fiber connector Product features
1. The technology can be utilized in systems such as an aircraft, electronic systems, ships, and weapons. Where the installation space is small the system is suitable. It embodies a rotary quick-lock for accomplishing multi-channel optical communication.
2. The external casing of the J599E6 series of beam-expanding high-speed optical fiber connectors can be constructed of various materials and have different coatings to be conditioned for any environment.
3. Five-key positioning, with functions of blind insertion and error-proof insertion;
4. Bayonet structure, quick connection;
5. The contact parts of the J599E6 series of beam expansion type high-density optical fiber connectors are made of collimating lenses, with non-contact connection, and the end faces do not damage easily.

TFC, a company with a highly standardized workshop of over 6,000 square meters, was established in 2015 and is based in Changsha, Hunan. The enterprise, which is driven by the motto "Making every connection more reliable, making every piece of data more accurate", intends to provide the market with high-performance component products and accompanying solutions. As a national high-tech enterprise integrating R&D, production, testing, and sales, TFC has three core business divisions Instrumentation, Connectors, and Sensors. The company is also capable of handling a variety of technical issues that fall under the four categories of signal connection, signal conditioning, signal switching, and signal detection technologies.
Q1: What is the function of the "five-key positioning" design of the J599E6 series connectors?
A1: The five-key locating design is basically the two core ideas. To begin with, it allows blind insertion meaning that connection can be done without exact alignment thus it is good for situations where there is little space for installation. The other one is to get anti-misconnection protection in order to avoid the breaking of the unit or the connectors by the wrong connection of the ports.
Q2: How is "contactless connection" achieved and what are its advantages?
A2: Non-contact connection can be done by the installation of a collimating lens on the contact piece - the light beam is collimated by the lens and then sent, thus it is not necessary to come in direct contact with the end face of the contact piece. The benefits are in: ① End face wear or scratches are avoided thus the life of the contacting parts is prolonged; ② The light spot that is emitted is large and the device is not sensitive to dust, thus the signal loss caused by dirt is less.
Q3: What are the insertion loss and return loss of this series of connectors at different wavelengths?
A3: The optical performance parameters are dependent on the wavelength: ① Insertion loss: ≤0.6dB at 850nm wavelength, ≤0.8dB at 1310nm wavelength; ② Return loss: ≥20dB at a wavelength of 850nm and ≥45dB at a wavelength of 1310nm.
