Abstract
The invention discloses a method for testing Ethernet passive optical network devices. The method includes registering a virtually added optical network unit ONU in an online manner after a test instruction is acquired, and allocating logic link identification and fixed bandwidth to the ONU; pushing an Ethernet test message to a downlink channel, and encapsulating the test message into a unicast data frame in the downlink channel; looping the unicast data frame back to an uplink channel; de-encapsulating the unicast data frame in the uplink channel, and pushing a test message obtained after the unicast data frame is de-encapsulated out of the uplink channel; and outputting a response indicating that an Ethernet passive optical network device runs normally during a test when the test message pushed out of the unlink channel is identical to the test message pushed to the downlink channel.

Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of method of testing and equipment of Ethernet passive optical network equipment.
Background technology
Ethernet passive optical network (EPON, Ethernet Passive Optical Network) technology take optical fiber as transmission medium, by up-downgoing wavelength division multiplexing, realizes single fiber bi-directional communication; Broadcasted by down direction, the time-multiplexed technology of up direction achieves point-to-multipoint communication simultaneously.
EPON system is by the optical line terminal (OLT of local side, Optical Line Terminal), optical fiber splitter (ODN, Optical Distribution Node) and optical network unit (ONU, OpticalNetwork Unit) three part compositions, because EPON is a point-to-multi-point system, therefore there is the possibility of network conflict, so adopt time-multiplexed way share same optical channel transmission data to allow multiple ONU in EPON system.
In order to the smooth evolution of the compatibility and network that realize 10G EPON and 1G EPON, IEEE 802.3av standard has special consideration, to ensure 10G EPON and 1G EPON system coexisting under same ODN in Wavelength Assignment, multiparty control mechanism.
In EPON system, in order to realize the compatibility of 10G EPON and 1G EPON, in wavelength planning, the downstream wavelength of the 1490nm that 10G EPON does not use 1G EPON system to use, IEEE802.3av Standard Selection 1577nm is as the wavelength (wave-length coverage 1574 ~ 1580nm) of 10Gbit/s downstream signal.Therefore, at down direction, 10Gbit/s signal and 1Gbit/s signal are wavelength division multiplexing (WDM, Wavelength Division Multiplexing) mode.And up direction, the wavelength of 1Gbit/s signal is 1310nm (wave-length coverage 1260 ~ 1360nm), the up wavelength of IEEE 802.3av standard regulation 10Gbit/s signal is 1270nm (wave-length coverage 1260 ~ 1280nm), the two has overlap, therefore WDM mode can not be adopted, dual rate time division multiplexing can only be adopted to access (TDMA, Time DivisionMultiple Access) mode.Such 10G EPON OLT can find 10G/10G, 10G/1G and 1G/1G tri-kinds of ONU simultaneously.
Prior art is each passive optical-fiber network (PON to the method for testing of 10G EPON equipment, Passive Optical Network) hang three types ONU and carry out docking networking under the optical splitter that connects of mouth, whether the use ethernet traffic device testing authentication OLT that carries out giving out a contract for a project that gives out a contract for a project is normal.
The present inventor finds, for for detecting 10G EPON 10G, 1G Serdes and PON MAC normal data traffic hardware corridor in prior art, standard 10G EPON port need be equipped with an optical module, a 1:4 or and above splitting ratio optical splitter, three types test terminal.For 4 mouthfuls of 10GEPON veneers, at least need outfit 4 optical modules, 12 terminals and 4 optical splitters.Outfit 24 terminals and 8 optical splitters are then needed for 8 mouthfuls of 10G EPON veneers.And each veneer needs a flow instrument, such test macro, test program is complicated, and testing cost is high.
