Embodiment
As shown in Figure 1, passive optical network of the present invention is made up of optical line terminal (OLT) 12, optical branching device 14, optical network unit (ONU) 16 and the optical fiber that connects these equipment, OLT is as local side apparatus, be connected with optical branching device 14 by a trunk optical fiber, optical branching device connects each ONU by independent branch optical fiber.At down direction, optical branching device is realized the beam split function, by branch optical fiber the downlink optical signal of OLT12 is sent to all ONU16; At up direction, optical branching device 14 is realized the light signal aggregation feature, and the light signal that ONU16 is sent converges, and sends to OLT12 by trunk optical fiber.
As shown in Figure 2, passive optical network equipment 20 of the present invention can be ONU, OLT or optical branching device, specifically comprises service access module 22, transmits control module 24 and uplink module 26.Wherein, service access module 22 is used for the network with the ustomer premises access equipment access carrier, transmits control module 24 and is used for up data are transmitted to uplink module 26.Embodiments of the invention design the MAC of two or more upstream Interfaces in the uplink module of passive optical network equipment 20, similar interface MAC such as for example present GPON MAC, EPON MAC, GE MAC, 10GE PON MAC, 10G GPON MAC, the particular hardware implementation can be a hardware MAC chip independently, also can realize by optical splitter/combiner, certainly can also realize by chip ASIC, perhaps comprise and transmit the ASIC that control module 24 realizes together.
As shown in Figure 3, the realization flow of method of the present invention is as follows:
Step 1: power on or reset to passive optical network equipment
Step 2: passive optical network equipment is determined the type of current network according to the signal that receives, for example passive optical network equipment can be determined the type of current network by the physical layer synchronization information that detects higher level's network, also can determine the type of current network according to the physical layer device optical module difference in the network, if optical module adopt be extended pattern SFP module then think that the current network type is the GE pattern; If optical module adopts the bimodulus module, can read optical module information and think that then the current network type is the xPON pattern.
Step 3: passive optical network equipment judges whether the interface modes of current preset and the type of current network mate, if concrete passive optical network equipment can obtain frame synchronization information, then can think the interface modes of current preset and the type matching of current network, if frame synchronization information is lost, think that then the interface modes of current preset and the type of current network do not match.
Step 4: if mate then passive optical network equipment enters normal operating conditions, if do not match then interface modes that passive optical network equipment selects a type with current network to be complementary automatically, passive optical network equipment enters normal operating conditions then.
Certainly, those skilled in the art will be appreciated that, in above-mentioned step 4, when if the type of the interface modes of current preset and current network does not match, the interface modes that also can directly not select a type with current network to be complementary, but the next interface modes of redirect sequentially, and then judge whether the type of interface modes and current network mates, if do not match then continue redirect another one interface modes, till coupling.
Step 5: passive optical network equipment enters normal operating conditions further will work as the memory cell that the pattern information of front port is stored in passive optical network equipment afterwards, so that passive optical network equipment directly started with the pattern of this storage when started next time, do not need once more automatic adaptation network, improve the speed of network, for the user provides better experience.
Embodiments of the invention are by being provided with the interface with two or more mode of operations on passive optical network equipment, the pattern that passive optical network equipment can select a type with current network to be complementary from the multiple mode of operation of described interface automatically, realize the Adaptive matching of interface, can realize professional pre-configured and automatic granting, can significantly reduce the equipment control and the maintenance cost of Virtual network operator, simultaneously can reduce unit type and kind, offer convenience for equipment vendor exploitation and operator store, meet current operator non-maintaining to equipment, the demand for development of zero contact (ZERO TOUCH).
More than be the explanation to the specific embodiment of the invention, those of ordinary skill in the art can carry out suitable improvement and change to the solution of the present invention in concrete implementation process, to adapt to the needs of concrete condition.Therefore, the specific embodiment of the present invention just plays an exemplary role, not in order to restriction protection scope of the present invention.
