Description

A kind of optical fibre communication method

Technical field

What the present invention relates to is a kind of wiring technique that is intended to reduce between mobile unit, is a kind of optical fibre communication method specifically.

Background technology

At present, vehicular communication equipment is of a great variety, equips the cable between equipment in the inner confined space and is on the increase, and the reliability of communication, the maintainability of equipment become the key factor that affects equipment performance. The impact of natural separation when communication cable is easily subject to stretching in installation process, carrying and electromagnetic interference, mechanical force, ground connection etc., finally causes equipment normally to move.

Summary of the invention

In order to address this problem, the present invention proposes a kind of optical fibre communication method. Fiber optic communication has lightweight, improves the mobility of communication system, further reduces field operations hauled weight, strengthens the flexibility in launching; Antijamming capability is strong, strong security, and enemy cannot survey and implement to disturb; Reducing wiring quantity provides the advantages such as more free space, therefore, adopts fiber optic communication to carry out the line between minimizing equipment, effectively promotes the battlefield adaptability of military equipment.

Technical problem to be solved by this invention is to utilize fiber optic communication advantage to solve the technology of coaxial cable communication drawback.

According to the invention process, mainly containing several important technical problems needs to solve: different wave length optical communication technique, signal compatibility technology.

Wherein different wave length optical communication technique mainly adopts the optical-electric module of different wave length, then becomes a road optical fiber by CWDM (CWDM module), or realizes communication by a branch of optical fiber.

Wherein signal compatibility technology mainly adopts special chip to process the signal of different rates, is then converted into optical signal by optical-electric module.

Various signal is by corresponding communication interface access fpga chip, then fpga chip Dui Ge road signal is changed, be converted to ethernet frame by total interface signal, then multiple connection is that the optical signal of 10Gbps Ethernet transmits, and XAUI interface rate is 3.125Gbps

Receiving terminal is the mirror image of transmitting terminal, and transmitting terminal is mainly the optical signal that the total interface signal of telecommunication is converted to respectively to different wave length, is then that CWDM module becomes a road optical fiber by CWDM. Two-way signaling need use 2 CWDM modules.

The beneficial effect that this invention brings is:

1, alleviate light weight, promote mobility, there is good environmental suitability.

2, make full use of the advantage of fiber optic communication, promote traffic rate, strengthen antijamming capability.

3, reduce the difficulty of wiring, the maintainability of lifting means.

Detailed description of the invention

Content of the present invention is carried out to more detailed elaboration below:

As shown in Figure 1, this system block diagram is a schematic diagram, has more than and is confined to above interface, and wherein recovery connects the photoelectricity that transport module mainly completes different transmission rates signal and transforms each other, can carry out as required the optical fiber of varying number and select between sending and receiving end.

Signal compatibility scheme is as shown in Figure 2:

Various signal is by corresponding communication interface access fpga chip, then fpga chip Dui Ge road signal is changed, be converted to ethernet frame by total interface signal, then multiple connection is that the optical signal of 10Gbps Ethernet transmits, and XAUI interface rate is 3.125Gbps.

This scheme has single optical interface, low in energy consumption, and cost is low, the advantage that volume is little.

Fig. 3 is the schematic diagram of transmitting terminal, and receiving terminal is the mirror image of transmitting terminal, is mainly the optical signal that the total interface signal of telecommunication is converted to respectively to different wave length, then becomes a road optical fiber by CWDM (CWDM module). Two-way signaling need use 2 CWDM modules.

This scheme has the advantages such as single optical fiber, antijamming capability be strong.

Because this invention can effectively reduce the equipment weight of carrying communication equipment, the communication efficiency of raising equipment etc. can be widely used in every field.
