Structure and method for tracking optical cable using light pipe on fan-out kit

Technical Field

The invention relates to the technical field of optical cable maintenance, in particular to a structure and a method for tracking an optical cable by using a light guide pipe on a fan-out kit.

Background

There are a large number of optical fiber jumpers (fiber optic cables) on the servers or switches. If a certain optical fiber connection fails, the system will transmit failure information to the technician, but the specific search work will be completed manually by the technician, and the specific operation mode is as follows: the server or the switch finds the fault port, and the optical fiber jumper plugged along the fault port finds the other end of the optical fiber jumper. When the number of the optical fiber jumpers is small, the work is simple and short in time consumption, but once the number of the optical fiber jumpers is large, the magnitude of the work is increased, and the optical fiber jumpers are crossed, wound, twisted and the like, so that the difficulty of searching work is further increased.

In order to solve the problem, LED lamps are arranged at two ends of an optical fiber jumper wire, when the optical fiber jumper wire is found, a light source switch of the optical fiber jumper wire can be turned on at one end of the optical fiber jumper wire, and then the LED lamps at the two ends are turned on, so that technicians can search the other end of the optical fiber jumper wire. However, the prior art has the following defects: every optic fibre wire jumper all needs extra plus power supply (be the battery case usually), and both ends all need set up LED lamp and the switch that corresponds, and the total cost is higher and not environmental protection.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides an optical cable tracking structure and an optical cable tracking method without additionally arranging a battery and an LED lamp.

The technical scheme of the invention is as follows:

the structure for tracking the optical cable by using the optical conduit on the fan-out sleeve comprises the fan-out sleeve, the optical cable and the optical conduit, wherein a sheath of the optical cable is arranged on the front section and the rear section of the optical cable in a broken line mode, the fan-out sleeve is a shell split up from top to bottom, the optical conduit comprises two optical guide heads and tracing optical fibers connected with the two optical guide heads, the two optical guide heads are respectively installed on the two fan-out sleeves, the front ends of the two optical guide heads respectively extend out of the front end face of the fan-out sleeve, and the tracing optical fibers and the cable core of the optical cable jointly penetrate through the sheath.

Furthermore, the light guide head comprises a light guide column and a V-shaped groove, an arc-shaped lens is formed at the front end of the light guide column, a plurality of concave rings are inwards recessed in the middle section of the light guide column, the end face of the rear end of the light guide column is tightly connected with the V-shaped groove, a tracing optical fiber is clamped in the groove of the V-shaped groove, and the end part of the tracing optical fiber is tightly attached to the center of the end face of the rear end of the light guide column.

Further, the leaded light post rear end is connected with a limiting plate, limiting plate central authorities are provided with the breach of cooperation V type groove and spike optic fibre, and the meaning of limiting plate lies in preventing that the leaded light post breaks away from the fan-out external member.

Further, be provided with a plurality of spacing posts in the fan-out external member for keep apart the sinle silk of spike optic fibre and optical cable, prevent that the optical cable from dragging the time because the pulling of sinle silk drives spike optic fibre. And Kevlar fiber (the reinforcing part of the optical cable) in the optical cable surrounds the limiting column, because Kevlar fiber is inevitably carried by tensile force at the broken line part of the optical cable, when the limiting column contacts the Kevlar fiber and generates certain axial limiting, the protective effect can be generated on the wire core and the tracing optical fiber.

A method of tracking a fiber optic cable using a light pipe on a fan-out package, comprising the steps of:

step one, a portable light source (such as a flashlight, a laser pen, a fiber red light pen and the like) is used for irradiating a lens of a light guide head of a fan-out kit at one end, corresponding to a fault port, of an optical cable;

and secondly, checking whether other light guide heads except the light guide head irradiated by the portable light source have a light emitting phenomenon or not, wherein a fan-out kit corresponding to the light guide head emitting light is also the other end of the target optical cable.

The invention has the beneficial effects that: a battery box, an LED lamp and a corresponding switch are not required to be arranged on the optical cable, so that the production cost is greatly reduced; because a battery box is not required to be arranged, the pollution of waste batteries is avoided; is convenient to use.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

as shown in fig. 1-3, a structure for tracking an optical cable by using a light guide on a fan-out kit comprises the fan-out kit, the optical cable and the light guide, wherein a sheath of the optical cable is arranged on the front section and the rear section of the optical cable in a broken line manner and is covered with the fan-out kit, the fan-out kit is a shell split up and down, the light guide comprises two light guide heads and tracing fibers connected with the two light guide heads, the two light guide heads are respectively installed on the two fan-out kits, the front ends of the two light guide heads respectively extend out of the front end face of the fan-out kit, and the tracing fibers and the core of the optical.

The light guide head includes leaded light post and V type groove, the leaded light post front end is formed with curved lens, the leaded light post middle section is inwards sunken to have a plurality of concave ring, and leaded light post rear end terminal surface zonulae occludens has V type groove, and the inslot centre gripping in V type groove has the spike optic fibre, the tight laminating of spike optic fibre tip is in leaded light post rear end terminal surface central authorities.

The utility model discloses a fan-out external member, including leaded light post, limiting plate, the significance of limiting plate lies in preventing that the leaded light post breaks away from the fan-out external member.

Be provided with a plurality of spacing posts in the fan-out external member for keep apart the sinle silk of spike optic fibre and optical cable, because the pulling of sinle silk drives spike optic fibre when preventing that the optical cable from dragging.
