Problems solved by technology
[0003] Commonly used adjustable optical transmission devices include: optical transceivers, optical fiber transceivers, optical switches, PDH, SDH, PTN and other types of equipment, these devices need to be powered on when in use, and traditional adjustable optical transmission devices will be equipped with A detachable power cord, but this kind of power cord is not adjustable in length, so when in use, when the length is not long enough, it will need to be used with a terminal block, which is not very convenient to use, and, because the power cord can be Detachability, therefore, it is easy to cause the loss of the power cord, which will affect the use

The invention provides an adjustable optical transmission device, comprising a base, an optical transmission body arranged on the base, and a containing mechanism fixedly mounted at the left end of the optical transmission body. A rolling mechanism is arranged on the base, and comprises mounting grooves and pulleys. A first rotating groove with the opening facing forward is formed in the containing mechanism, and a second rotating groove communicated with the first rotating groove is formed in the rear end wall of the first rotating groove. A rotating shaft is rotatably mounted in the first rotating groove through a bearing, a conductive column extending backward is fixedly mounted in the rotating shaft, and the rear end of the conductive column extends into and is in rotation fit with thesecond rotating groove. A circle of limiting rings are arranged on the outer side wall of the conductive column, and correspondingly, a circle of annular limiting grooves are formed in the inner sidewall of the second rotating groove. A containing groove is formed in the left end face of the containing mechanism, a through groove is formed between the containing groove and the first rotating groove, and a winding groove is formed in the rotating shaft.
Description
technical field [0001] The invention relates to the field of light transmission, in particular to an adjustable light transmission device. Background technique [0002] As a tool for converting various signals into optical signals and transmitting them on optical fibers, adjustable optical transmission devices have become the cornerstone of today's information superhighway. Commonly used adjustable optical transmission devices include synchronous digital system, packet transmission network and other types of equipment. These commonly used adjustable optical transmission devices not only carry the transmission of traditional analog signals such as telephone voice, audio, video, etc., but also carry data signals used by various industries and households today, such as Ethernet. [0003] Commonly used adjustable optical transmission devices include: optical transceivers, optical fiber transceivers, optical switches, PDH, SDH, PTN and other types of equipment, these devices nee...
