Description
Technical field
This utility model relates to a kind of amplifier installation, a kind of can situ configuration and the amplifier installation of upgrading.
Background technology
Fibre Optical Communication Technology, since coming out, has constantly advanced all along two targets.One is to extend repeater span,
Two is to improve transfer rate.After erbium-doped fiber amplifier (EDFA) occurs, new transmission range record constantly breaks through, in nothing
The transmission range that continues is continuously increased.The appearance of raman amplifier, increases further without electrically regenerative repeater span.Raman amplifier is to pass
Losing fine is gain media, can carry out transmission limit, limit and amplify, and relative EDFA jumped amplifier can improve system further
Signal to noise ratio.Along with electric power transmits, the application of the repeatless transmission system such as undersea transmission is more and more extensive, and raman amplifier becomes more
Come the most important.Along with being gradually increased of gain requirement, owing in optical fiber, single and the noise problem that double times Rayleigh scattering causes exist
Largely limit the raising of systematic function.So common single order Raman is to the improvement of system transfers performance or limited
's.
Raman amplifierFRAIt is to utilize the Raman scattering effect in optical fiber to be converted into by the energy of short wavelength's pump light
The energy of long wavelength signals light.13.2THz(1550nm communication window about 100nm is had between pump light and flashlight peak value)
Frequency displacement.Higher-order Raman effect be also referred to as repeatedly Raman scattering, be i.e. positioned at high frequency high-power photon energy can through for several times this
Stokes shift, step by step pumping low frequency photon.Its principle be tradition pump light P1 wavelength Stokes shift on again
Introduce High-Order Pump source P2, by P1 as the pump-coupling source of flashlight.So Pl loss in a fiber can be produced by P2
Gain compensate, decrease the pumping depletion impact on Raman gain, P1 in a fiber power distribution more level off to constant
Value, thus the effect amplified further up to distribution.The order of Raman lasing is that energy is transferred to 2 rank by 3 rank pump lights successively
Pump light, energy is transferred to 1 rank pump light by 2 rank pump lights, and energy is transferred to flashlight by 1 rank pump light, according to 3 rank-> 2
The order of rank, rank-> 1-> flashlight carries out power transfer successively.
One section of erbium-doped fiber (EDF) is inserted in Transmission Fibers by remote optical pumping amplifier (ROPA), is carried by special pumping
Optical fiber or Transmission Fibers itself, enter EDF from far-end note pump light, collection overall gain is incorporated in transmission span, distant pump light source
Generally use the 1480nm laser instrument of watt level, with the loss problem overcoming long-distance optical fiber to transmit.The distant pump efficiency of high-order should also be base
The principle scattered in above-mentioned Higher-order Raman realizes.
The use of raman amplifier and remote optical pumping amplifier at present has become as overlength span repeaterless fiber communication system not
The key technology that can or lack.3 rank raman amplifiers have the most abroad been had to realize the laboratory result of 600km transmission.From domestic
From the point of view of over distance state of development, the transmission demand of 400km has occurred, needs along with more than the development 500km of technology transmits
Ask and also there will be.So the demand of amplifier technique also can be gradually stepped up.
Typically optical amplifier can be configured according to transmission range or loss engineering design when.Such as, when
The when that span being within 250km, configure raman amplifier;Distance is lengthened to 350 km further, needs to configure distant pump and amplifies
Device;Distance continues lengthening more than 400km, it is necessary to configuration raman amplifier adds remote optical pumping amplifier or high-order rank raman amplifier
Or high-order remote optical pumping amplifier.But we find have some non-relay in actual repeaterless transmission research and application process
Transmission system only has transmission range can not make good budget, and the situation underestimating/over-evaluate transmission demand all happens occasionally, this
Result in amplifier customized before going into operation may not mate in actual use, be sometimes that design margin is not enough, have
Time again be probably design waste.In addition job site is due to factors such as landform, environment, and machine room sending and receiving end situation is not equal, amplifies
Device allocation plan generally requires scene and again plans with customized, thus causes the waste of funds and resource.
