Abstract

The utility model provides a router with plastic optical fiber interface, which comprises a built-in optical fiber receiving-transmitting module and a plastic optical fiber interface for directly inserting a plastic optical fiber in the optical fiber receiving-transmitting module. Since the optical fiber receiving-transmitting module is arranged in the router, plastic optical fibers can be conveniently used to finish the interconnection with a network device, and the router has the advantages of convenient connection and small volume.

Description

A kind of router with plastic fiber interface

Technical field

The utility model relates to a kind of router, specifically, relates to a kind of router with plastic fiber interface.

Background technology

So-called " route " is meant the behavior and the action that data are sent to another place from a place, and router, carries out the machine of this behavior act just, and its English name is Router.Router is made up of hardware and software.Hardware mainly is made up of physical hardwares such as central processing unit (CPU), internal memory, interface, control port and circuit.The router network interface is used for receiving the different physical network medium of packet, has determined it to have different network interfaces, and as corresponding to the 10Base-T Ethernet, router has the 10Base-T Ethernet interface.

Ethernet technology has experienced 30 years of development, and its transmission rate rises to 10Gbps from 10Mbps, and presents optimistic prospect, and this mainly gives the credit to its superiority.Plurality of advantages such as that Ethernet has is simple in structure, with low cost, bandwidth is easy to expansion and compatible good.In new Control Network structure, Ethernet is substituting traditional control bus gradually.The RJ-45 port is modal twisted-pair Ethernet interface, because also mainly adopt twisted-pair feeder as transmission medium in Fast Ethernet, the Ethernet interface of the router that existing market exists all is to link to each other with other network equipments by the RJ-45 port.

And plastic fiber (POF) is compared with silica fiber as novel data transmission media, has the big and good advantages such as pliability of thicker core diameter, acceptance angle, thus easy to connect, the coupling efficiency height; The advantage that has high bandwidth, vibration resistance, radioresistance, low price, easy construction is simultaneously compared with twisted-pair feeder, and is in light weight, no electromagnetic interference, and bandwidth is big, is best short-range data transmission medium.

But because present router all is to have only the RJ-45 port,, also must carry out opto-electronic conversion by an external plastic fiber media converter if use plastic fiber, very inconvenient.As shown in Figure 2.

The utility model content

The purpose of this utility model is to overcome existing router and can't directly uses plastic fiber to connect the deficiency of the network equipment, a kind of built-in plastic fiber transceiver module is provided and has the plastic fiber interface, and plastic fiber can direct-insert router.

In order to realize the purpose of this utility model, plastic fiber router described in the utility model, it comprises that also a built-in fiber transceiver module and directly inserts plastic fiber interface in the described optical fiber transceiver module with plastic fiber.

Described plastic fiber interface is the interface that can use the plastic fiber connector to match with SMI type, SC type or SC-RJ type etc., and the plastic fiber interface is to be different from the present Ethernet RJ-45 interface commonly used and the SFP type interface of silica fiber.

Described plastic fiber interface also can adopt FIRECOMMS company

The connectorless system.

Plastic fiber transceiver module described in the utility model meets ethernet standard, the optical fiber transceiver module is based on the 650nm plastic fiber transceiver of high speed resonant cavity LED (RCLED) technology, and transceiver interface is a FIRECOMMS company

Connectorless system or the interface that can use the plastic fiber connector to match with SMI type, SC type or SC-RJ type etc.

The utility model router is connected used plastic fiber with network can be SI type or GI plastic optical fiber.

The utility model router is because at the built-in plastic fiber transceiver module of router, can use plastic fiber to finish interconnection with the network equipment easily, have easy to connect, the advantage that volume is little.

Embodiment

Cooperate appended graphic explanation in detail by specific embodiment below, so that the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.

Fig. 3 is the structured flowchart of plastic fiber router described in the utility model.As shown in Figure 3, plastic fiber router of the present utility model is the same with router well known in the art, comprise access controller, parts such as card reader, electric lock also comprise built-in fiber transceiver module and the plastic fiber interface that plastic fiber directly can be inserted in the optical fiber transceiver module simultaneously.

Optical fiber transceiver module of the present utility model is different from existing silica fiber transceiver module, and the operation wavelength of employing is a visible light, and the silica fiber operation wavelength is 850/1310/1550 (nm).The optical fiber transceiver module can use FIRECOMMS company

Plugless plastic fiber transceiver.As Fast Ethernet physical layer adaptive transceiver.Because it supports IEEE 802.3 standards, provides The plugless interface can support MAC, and router interior just in time is integrated with the Ethernet medium access controller, can realize with

The seamless link of plugless plastic fiber transceiver.

Plastic fiber interface of the present utility model can be the OptoLock of FIRECOMMS company, also can be the interface that matches with plastic fiber connectors such as SMI type, SC type or SC-RJ types.

Fig. 4 is the connection diagram of the router described in the utility model and the network equipment.The utility model router is because at the built-in plastic fiber transceiver module of router, can use plastic fiber to finish interconnection with the network equipment easily, have easy to connect, the advantage that volume is little.Being connected used plastic fiber with network can be SI type or GI plastic optical fiber.

Although the utility model has been done detailed explanation and quoted some instantiations as proof, for a person skilled in the art, only otherwise leave spirit and scope of the present utility model, it is obvious doing various variations or correction.
