Abstract
Description
The present invention relates to an RN terminator, and in particular, a through-hole is formed in a cap for an optical adapter inserted into an optical adapter port of a remote node (RN) used for building a fiber to the home (FTTH) network. By connecting to, and using at least one optical adapter cap connected to the cap ring connected to the fastening ring to prevent the loss of the RN terminator, and relates to the RN terminator that can easily check the presence or absence of unused ports.
Telecommunications operators have installed optical cables in place of existing coaxial cables to process large amounts of information at high speed, and FTTH networks are being built to each home by using these cables.
The RN used in the construction of the FTTH network is a remote node for connecting the optical cables coming from the telephone company and branching them into optical fibers and connecting them with the optical outdoor beams coming from the optical terminal boxes of each generation. It is installed at the height of the back (high position).
The branched optical fibers and the out-of-air rays coming from each generation optical terminal box are connected by the optical adapter inside the RN, and each out-of-rays incoming from the generation terminal box are connected to each port of the optical adapter by the optical connector. It can be connected to the optical fiber by (plugging).
An optical adapter can have multiple ports (4 ports, 8 ports, 12 ports, etc.) to allow multiple or more out-of-doors to be connected, and some of these ports may be used for reasons such as accepting new subscribers or canceling existing subscribers. It can be left unconnected and the number of ports left unconnected is variable.
On the other hand, even if an unused port is left unsealed, optical adapters such as terminators may be damaged due to poor connection of individual subscribers or failure of local networks due to backlighting, rainwater flooding or contamination of foreign matter (yellow dust, dust, insects). It is common to insert individual caps into unused ports.
However, these individually inserted caps are often lost or damaged during the out-of-air construction at the sue for new subscribers or subscribers, so unused ports are left unopened.
In addition, the RN is installed at the height of the telephone pole or the outer wall of the building, and the optical adapter is stored inside the closed RN enclosure, so information on the presence or the number of unconnected ports of the optical adapter is not easily understood from the ground. In order to grasp, there is a problem that a worker must take the risk of having to climb directly to the height where the RN is installed, and the inconvenience of having to check the opening of the enclosure.
The present invention forms a through hole in the cap for the optical adapter that is inserted into the optical adapter port of the RN (Remote Node: Remote Node) used for building a FTTH (Fiber To The Home) network, and connects a cap line, and at least one cap line is connected. It is an object of the present invention to provide an RN terminator which can prevent the loss of the RN terminator and easily check the presence or the number of unused ports by connecting the cap for the optical adapter to the fastening ring.
The problems of the present invention are solved by the RN terminator of the present invention as follows.
RN terminator of the present invention,
At least one cap including an insertion portion inserted into a port of the optical adapter and a protrusion extending in the longitudinal direction of the insertion portion and protruding perpendicularly to the longitudinal direction and not inserted into the port of the optical adapter and having at least one through hole formed therein;
One fastening ring; And
One end is a knot passing through the through-hole formed in the protrusion of the cap, the other end is formed at least one cap cord formed of a knot intersecting the fastening ring; is configured to include.
In the RN terminal device of the present invention, the cap has a T shape.
In the RN terminal device of the present invention, the through hole is formed toward the side of the protrusion at the end of the protrusion.
In the RN terminal device of the present invention, the fastening ring is characterized in that the opening and closing.
In the RN terminal device of the present invention, the shape of the fastening ring is characterized by any one of a long inverted triangle, a snowman shape or a peanut shape with rounded corners.
The RN terminator of the present invention may further comprise a tube surrounding the knot.
In the RN terminal device of the present invention, the tube is made of a material comprising a fluorescent material.
In the RN terminal of the present invention, the tube is characterized in that it has a color indicating the carrier.
Using the RN terminator of the present invention,
First, the caps for the optical adapters are lost, so there is no risk of leaving the ports of the optical adapters open, which reduces the cost of cap purchase and facilitates the management of the optical adapter ports, as well as backlighting, rainwater ingress or foreign matter (yellow, dust, insects) ) Significantly reduce the inaccessibility of individual subscribers or the failure of local network due to pollution, etc.
Secondly, since the cap string or tube of the present invention is exposed to extend out of the RN enclosure, the unused port can be easily used on the ground without taking the risk of the operator having to climb directly to the height where the RN is installed and the inconvenience of opening the enclosure. It is easy to grasp the presence and the number of subscribers, and it is effective to prepare the subscriber customer opening efficiently.
