Abstract
The utility model discloses a microscopic dual-fiber bidirectional DIN type optical transceiver module with high reliability, which comprises an all-metal case, one end of the case is equipped with two optical interfaces while the other end is equipped with an electrical interface, and the two optical interfaces match with DIN cable interfaces and are in fixing and sealing connection with the two DIN cable interfaces respectively. The utility model has the advantages of sound sealing performance, vibration resistance, electromagnetic interference resistance, heat and humidity resistance, high temperature adaptability and small dimensions and the like. Besides, users can arrange more moulds in the same space, and thereby the utility model is high in cost-performance ratio.
Description
Technical field
The utility model relates to the optical transceiver module in a kind of optical communication system, relates in particular to the miniature two fine two-way DIN type optical transceiver modules of a kind of high reliability.
Background technology
Along with the application widely of photovoltaic, light transmitting-receiving subassembly role in product is more and more crucial, often is directly connected to the properties of product quality.Along with the development of technology, the profile of light transmitting-receiving subassembly is more and more littler, and transfer rate is also more and more higher.Common light transmitting-receiving subassembly profile form has 1 * 9 standard, GBIC, SFP, SFF etc., and speed has also contained from DC level to the lucky bits per second of number.But standard light transceiver module profile form is fixed, quality grade is not high, environmental suitability is low.And the product of some specific uses often has higher requirement to the light transmitting-receiving subassembly, as sealing property, environmental suitability, physical dimension etc.Original smooth transmitting-receiving subassembly physical dimension overlength on the market, connection reliability are not high, can not meet design requirement.
The utility model content
The utility model discloses the miniature two fine two-way DIN type optical transceiver modules of a kind of high reliability, it comprises all-metal box body, one end of box body is provided with two light mouths, the other end of box body be provided with the electricity mouthful, two light mouths and the DIN cable interface is complementary and respectively with the fixed seal connection of two DIN cable interfaces.
Described box body is connected and composed by upper cartridge body and lower box body spot welding, offer two semicircle breach of mutual coupling on upper cartridge body and the lower box body respectively, four semicircle gap positions respectively are connected with the semicircular web member that is complementary with semicircle breach, when upper cartridge body and lower box body connected into the box body of sealing, four semicircle web member interlockings constituted described two light mouths; One end of lower box body has elliptical slot, and the table card has 10 identical electricity mouth leading foots of spacing in the elliptical slot, and elliptical slot constitutes described electric mouthful with electricity mouthful leading foot.
The bottom surface of lower box body is provided with two column screw thread pilot holes that box body is installed.
Also be provided with the square step of 4 position symmetries on the bottom surface of lower box body.
A described electricity mouthful leading foot spacing is 1mm.
Useful technique effect of the present utility model is: good seal performance, anti-vibration, anti-electromagnetic interference (EMI), moisture-proof heat, characteristics such as thermal adaptability is strong, physical dimension is little, the user can arrange more module under identical space, the cost performance height can be widely used in optical communication system.
