It is identical with prior art that present embodiment is not stated part.
Be the application of the present invention in actual production below.
(1) light sends choosing of receiving element
Knife rest island photoelectric composite submarine cable length is 3.5km to Ke Men port, Fuqing to the Pingtan.Submarine cable A, B, every mutually compound 16 core fibres of C three-phase amount to 48 cores.If all optical fiber in extra large cable A, B, the C three-phase are come and gone serial connection, then length can reach:
16?*?3?*?3.5km?=?168km
The knife rest island becomes OPGW length to advancing and is 14km.Circuitous 48 optical fiber of submarine cable that are connected in series are become OPGW with the knife rest island to advancing are connected from beginning to end, then obtain the maximum transmitted optical path length:
168km?+?2?*?14km?=?196km
Compound optical fiber is type monomode fiber G.652 in the submarine cable.Wavelength is that the light-decay characteristic coefficient in this type optical fiber, propagated of the light wave of 1310nm and 1550nm is following:
Optical 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)
Because the seabed fiber real-time monitoring system of this project development is intended to judge through the break-make of monitoring light path the state of optical fiber; In the light path of using, do not have the transmission of concrete business datum, thereby the chromatic dispersion size that produces during optical transmission is to the not significantly influence of operate as normal of system.And the light decay consumption needs emphasis to consider as a key factor of decision luminous power deposit.The maximum transmitted length of monitoring light path is 196km, and the light wave that the selective light attenuation is less, repeater span is long of should trying one's best can have enough luminous power deposits to guarantee the delivery optics end.Wavelength is that the light wave of 1550nm meets above condition.
Disposed the OSN2000 SDH of Huawei optical transmission device in the 110 kilovolts of changes of advancing in Pingtan.For guaranteeing the terminal enough luminous power deposits of long Distance Transmission light path, should select for use long apart from tabula rasa.Service data transmission not in the monitoring light path does not require bandwidth, thereby transmission rate is that the tabula rasa of 155Mbps enough uses.L1.2 type tabula rasa is the 155Mbps bandwidth, and the length of 1550nm wavelength window is apart from plate, luminous power is 0～-5dBm, optical receiver sensitivity is-30dBm to satisfy above demand.
(2) circuitous concatenated fiber core is counted Theoretical Calculation
Being selected in 110 kilovolts of Pingtans advances and becomes SDH optical transmission device OSN2000 and go up newly-increased light and send the receiving element model and be L1.2; At present can be according to per 100 km optical loss technical indicator; And the receiving sensitivity of combination light unit; Calculate the institute's ability incoming fiber optic total length that comprises part knife rest island, land to the change OPGW optical fiber that advances, to confirm the core number of circuitous concatenated fiber.
Sea, knife rest island cable length is 3.5km to Ke Men port, Fuqing to the Pingtan, and the knife rest island becomes OPGW length to advancing and is 15km.Consider the loss that optical fiber cabling and construction technology cause, the optical fiber specification is for G.652, and 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.Send the receiving element luminous power at the light that becomes configuration of advancing and be-5dBm, receiving sensitivity is-28dBm.The computing formula that the core of concatenated fiber counts n of then can making a circulation is:
（3.5km?*?n?+?15km?*?2）*?0.25dB/km?+?(?n?+?1)?*?0.05dB/km?<?28dBm?–?5dBm
Calculate n≤17, the maximum fibre core quantity theoretical value of the concatenated fiber that then can make a circulation is 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 inserts case; And on the optical transmission device of 110 kilovolts of changes of advancing; Comprehensive light source, the light power meter of using; OTDR and network management system are carried out on-the-spot test, uniting and adjustment, to confirm the best fibre core quantity that inserts.
The maximum fibre core quantity of round serial connection theoretical value to calculate is a starting quantity, the core number of the seabed fiber of the access monitoring system of successively decreasing one by one.Through repetition test and adjustment repeatedly, find, when the fibre core quantity of connecting system during greater than 12, the luminous power under-reserve that the monitoring system light path is terminal.The light decay consumption that light receiving unit is received fluctuates along with the variation of extraneous circumstances such as seawater trend, and monitoring system is prone to the phenomenon of mistake alarm, and equipment work is unstable.When the fibre core quantity of connecting system during less than 12, the terminal luminous power deposit of detection system light path is excessive, and light path occurs still leaving certain redundancy because monitoring system is received luminous power when unusual, can't in time alarm.To sum up can get, the best access fibre core quantity of taking into account the requirement of luminous power deposit and receiving sensitivity is 12.
(4) seabed fiber monitoring network element configuration
Selection advance become in the existing optical transmission device OSN2000 of Huawei as the access network element of fiber-optic monitoring.Dispose 2 L1.2 type tabula rasas, insert respectively in the 9th, 10 grooves, send receiving element, come respectively above-mentioned seabed fiber monitoring loopback 1 tunnel and seabed fiber monitoring loopback 2 tunnel to be carried out fiber-optic monitoring as light.Central machine room in Pingtan County accent main website is configured the equipment that becomes that advances through transmission network management.
For convenient communication attendant carries out monitoring management to seabed fiber ruuning situation nearby; This project is in NMS; Development of virtual seabed fiber monitoring remote network element; Being connected to advances becomes on the transmission equipment, the relevant seabed fiber network element monitoring of configuration groove position module and corresponding topological diagram interface.And, dispose the internal loopback loop by table 1 mode to the Virtual Monitoring remote network element of good development.
