Background technology
Along with the development of communication industry, user is more and more higher to the requirement of bandwidth, wireless access, and is accompanied by the expansion of city size, the increase of urban construction migration engineering, the network rebuilding project of communication enterprise is tending towards routinizing, and becomes a part very important in daily engineering project.Wherein the most general, also important with the adjustment of transmission equipment light path.
Original copper cable has exited communication stage gradually, is instead optical cable, and optical cable is large with its information capacity, long transmission distance, the advantages such as price is low, anti-interference and good confidentiality, have become so far irreplaceable circuit transmission means and have been widely used in the communications field.It is to meet one of growing bandwidth demand and the supporting indispensable engineering project of engineering construction that transformation to existing network, dilatation have become each large operation enterprise.In the network rebuilding, a step of most critical is exactly network cutover, and network migration is named again in network cutover, refers to operational network physics or change in logic.How safer, effective, carry out network cutover reliably, be always the communications industry pay close attention to problem.
Conventionally, service operation network requirement 24 hours is uninterrupted, and cutover is all generally circuit, operate to using, so network cutover will directly have influence on the business of carrying above, this cutover accidentally will cause the interruption of service application.How to formulate the most perfect project cutover, how to carry out the most perfect cutover, how to evade risk in cutover, how to reduce and even eliminate the impact on operation system, these are all that we need the thing of considering in detail before cutover.Once the preparation in early stage is done badly, and may run into a lot of beyond thought problems and cause delivery failure in cutover, even cannot return back to the state before cutover.
Given this, the present invention proposes a kind of construction method of safe and reliable effective optical path cutover.
Summary of the invention
The technical problem to be solved in the present invention be to provide one can be safely, effectively, optical path cutover method reliably.
The present invention solves above-mentioned technical problem by such technical scheme:
A method for optical path cutover, is characterized in that: the method comprises the following steps:
Step 001: former port, new port, jumper connection optical fiber are provided;
Step 002: lay jumper connection optical fiber, examine the design attitude of jumper connection optical fiber and former port;
Step 003: adjust test wavelength, make test wavelength identical with the optical wavelength that former port uses;
Step 004: optical time domain reflectometer is provided, utilize optical time domain reflectometer to measure and record to make new advances jumper connection optical line by omnidistance attenuation;
Step 005: light power meter is provided, utilizes light power meter test and the luminous power of described new jumper connection optical line by corresponding newly-increased port;
Step 006: by judging the input optical power value of new port, determine whether to carry out the cutover of light path,
Suppose that the normal input optical power scope of new port is R1～R2 (R1 > R2), the input optical power value of new port is RX,
In the time that RX is between R1 and R2, implement the cutover of light path,
In the time of RX > R1, at the receiving terminal of new port, optical power attenuation device is set, make input value between R1 and R2, then implement the cutover of light path,
In the time of RX < R2, improve the input power of new port, then implement the cutover of light path.
As a modification of the present invention, by high power port being set or shortening light path origin the input power that improves new port.
The present invention has the following advantages: the present invention utilizes optical time domain reflectometer and light power meter to carry out determination and analysis to the port for the treatment of cutover light path, and then makes safer, effective, reliable optical path cutover scheme according to actual conditions.
Accompanying drawing explanation
Fig. 1 is the flow process schematic flow diagram of optical path cutover method of the present invention.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, be the schematic flow sheet of the preferred embodiment of optical path cutover of the present invention, optical path cutover method provided by the invention comprises the steps:
Step 001: provide device board bit port using as former port, tail optical fiber, jumper connection optical fiber are provided;
Step 002: lay jumper connection optical fiber, examine the design attitude of jumper connection optical fiber and former port, link up route, carry out new jumping tail optical fiber mark and will be by the mark of cutover light path;
Step 003: adjust test wavelength, make test wavelength identical with the optical wavelength that former port uses;
Step 004: optical time domain reflectometer is provided, utilize optical time domain reflectometer (OTDR, OpticTime Domain Reflectometer) to measure and record to make new advances jumper connection optical line by omnidistance attenuation;
Step 005: light power meter is provided, utilizes light power meter test and the luminous power of described new jumper connection optical line by corresponding newly-increased port;
Step 006: use device software to check the situation of former port, and analyze, by judging the input optical power value of new port, determine whether to carry out the cutover of light path,
Suppose that the normal input optical power scope of new port is R1～R2 (R1 > R2), the input optical power value of new port is RX,
In the time that RX is between R1 and R2, implement the cutover of light path, wherein, when RX equates with R1 or R2, also can directly implement optical path cutover,
