It is same as the prior art that the present embodiment does not state part.
Be the application of the present invention in actual production below.
(1) the choosing of light transmission and reception unit
Ke Men port, Fuqing to knife rest island, Pingtan photoelectric composite submarine cable length is 3.5km.Submarine cable A, B, C three-phase every phase compound 16 core fibre, amounts to 48 cores.If all optical fiber in extra large cable A, B, C three-phase is come and gone serial connection, then length can reach:
16 * 3 * 3.5km = 168km
It is 14km that knife rest island becomes OPGW length to advancing.Submarine cable 48 optical fiber of roundabout serial connection are become OPGW head and the tail with knife rest island to advancing be connected, then obtain maximum transmitted optical path length:
168km + 2 * 14km = 196km
In submarine cable, the optical fiber of compound is G.652 type monomode fiber.Wavelength is that the light-decay characteristic coefficient that the light wave of 1310nm and 1550nm is propagated in this type optical fiber is as follows:
Fiber attenuation coefficient: a1 ￡ 0.34dB/km 1310nm(mean value);
A2 ￡ 0.36dB/km 1310nm(maximum);
A1 ￡ 0.20dB/km 1550nm(mean value);
A2 ￡ 0.21dB/km 1550nm(maximum).
Joint attenuation coefficient: ￡ 0.05dB/ (two-way mean value)
The seabed fiber real-time monitoring system developed due to this project break-make be intended to by monitoring light path judges the state of optical fiber, in the light path used, there is no the transmission of concrete business datum, the normal work of the dispersion size thus produced during optical transport on system does not significantly affect.And light decay consumption is as the key factor determining luminous power deposit, emphasis is needed to consider.The maximum transmitted length of monitoring light path is 196km, the light wave that selective light attenuation is less, repeater span is longer of should trying one's best, to ensure that transmission optical line terminal can have enough luminous power deposits.Wavelength is that the light wave of 1550nm meets above condition.
Huawei OSN2000 SDH optical transmission device has been configured with in the advance of 110 kilovolts, Pingtan becomes.For ensureing the luminous power deposit that long range propagation optical line terminal is enough, long distance tabula rasa should be selected.Not service data transmission in monitoring light path, to bandwidth not requirement, thus transmission rate is that the tabula rasa of 155Mbps enough uses.L1.2 type tabula rasa is 155Mbps bandwidth, and the long distance plate of 1550nm wavelength window, luminous power is 0 ~-5dBm, and optical receiver sensitivity is-30dBm, can meet above demand.
(2) roundabout concatenated fiber core number theory calculate
Being selected in newly-increased light transmission and reception unit model on 110 kilovolts, Pingtan advance change SDH optical transmission device OSN2000 is L1.2, now can according to per 100 km light loss technical indicator, and in conjunction with the receiving sensitivity of light unit, calculate and comprise part knife rest island, land becomes OPGW optical fiber institute's energy incoming fiber optic total length to advancing, to determine the core number of roundabout concatenated fiber.
Sea, Ke Men port, Fuqing to knife rest island, Pingtan cable length is 3.5km, and it is 15km that knife rest island becomes OPGW length to advancing.Consider that G.652 the loss that optical fiber cabling and construction technology cause, fiber dimensions are, wavelength is that the light per 100 km optical attenuation of 1550nm is by 0.25dB.Each enamel head place optical attenuation is by 0.05dB.Advancing, the light transmission and reception unit luminous power becoming configuration is-5dBm, and receiving sensitivity is-28dBm.Can the computing formula of core number n of roundabout concatenated fiber be then:
（3.5km * n + 15km * 2）* 0.25dB/km + ( n + 1) * 0.05dB/km < 28dBm – 5dBm
Calculating n≤17, then can the maximum fibre core quantity theoretical value of roundabout concatenated fiber be 17.
(3) optical receiver sensitivity adjustment
In debarkation point, submarine fiber cable both sides: the seabed fiber monitoring means on Fuqing Ke Mengang and knife rest island, Pingtan accesses case, and 110 kilovolts are advanced on the optical transmission device of change, comprehensive use light source, light power meter, OTDR and network management system carry out on-the-spot test, uniting and adjustment, to determine best access fibre core quantity.
With the round serial connection maximum fibre core quantity theoretical value calculated for starting quantity, the core number of the seabed fiber of access monitoring system of successively successively decreasing.By repetition test repeatedly and adjustment, find, when the fibre core quantity of connecting system is greater than 12, the luminous power under-reserve of monitoring system optical line terminal.The light decay consumption that light receiving unit receives fluctuates along with the change of the extraneous circumstances such as seawater trend, and the phenomenon of alarm by mistake easily appears in monitoring system, equipment job insecurity.When the fibre core quantity of connecting system is less than 12, the luminous power deposit of detection system optical line terminal is excessive, receives luminous power still leave certain redundancy when light path occurs abnormal due to monitoring system, cannot alarm in time.To sum up can obtain, the best access fibre core quantity taking into account luminous power deposit and receiving sensitivity requirement is 12.
(4) seabed fiber monitoring network element configuration
Select to advance and become the access network element of interior existing optical transmission device Huawei OSN2000 as fiber-optic monitoring.Configure 2 pieces of L1.2 type tabula rasas, respectively in insertion the 9th, 10 grooves, as light transmission and reception unit, come respectively loopback 2 road to be monitored to above-mentioned seabed fiber monitoring loopback 1 tunnel and seabed fiber and carry out fiber-optic monitoring.Adjust the central machine room of main website at Pingtan County, by transmission network management, the equipment become that advances is configured.
For convenience of communication, attendant carries out monitoring management to seabed fiber ruuning situation nearby, this project is in network management system, development of virtual seabed fiber monitoring remote network element, being connected to advances becomes on transmission equipment, the relevant seabed fiber network elements monitors slot module of configuration and corresponding topological diagram interface.And to the Virtual Monitoring remote network element developed, configure internal loopback loop by table 1 mode.
