Description
One, technical field
The utility model patent intelligent grid OPGW fiber optic serial communication implementation device relates to a kind of fiber optic serial relay communication implement device, and particularly a kind of GPON of utilization nest plate is realized fiber optic serial relay communication implement device.
Two, background technology
The GPON technique functions comes from the ATMPON technical standard that nineteen ninety-five begins to form gradually, and PON is the abbreviation of GPON English " EPON ".And GPON (Gigab it-Capab l e PON) is organized in September, 2002 proposition by FSAN the earliest, G.984.1 ITU-T has completed ITU-T and formulation G.984.2 in March, 2003 on this basis, has completed standardization G.984.3 in February, 2004 and June.Thereby finally formed the standard family of GPON.Equipment basic structure and existing PON based on the GPON technology are similar, also the OLT (optical line terminal) by local side, the ONT/ONU of user side (Optical Network Terminal or be called optical network unit) connects front two kinds of equipment and is comprised of ODN (Optical Distribution Network) and the network management system that monomode fiber (SM fiber) and passive optical splitters (Splitter) form.
The GPON characteristics:
(1) unprecedented high bandwidth.GPON speed is up to 2.5Gbps, can provide enough large bandwidth to satisfy the growing demand to high bandwidth of future network, and asymmetric property more can adapt to broadband data service market simultaneously.
(2) Full-Services access of QoS assurance.GPON can carry ATM cell and/or GEM frame simultaneously, and the ability that the grade of service well is provided, supports QoS assurance and Full-Services access is arranged.At present, the multiple services technology such as ATM voice-over, PDH, Ethernet are very ripe; The technology of using GEM to carry various customer services also obtains everybody consistent approval, has begun extensive use and development.
(3) support well the TDM business.The TDM business is mapped in the GEM frame, because GPON TC frame frame length is 125 μ s, can directly support the TDM business.The TDM business also can be mapped in ATM cell, also can provide the real-time Transmission that QoS guarantees.
(4) simple, efficient adaptive encapsulation.Adopt GEM to realize simple, efficient adaptive encapsulation to multi-business flow.In APON, all multi-business flows (speech, data traffic flow) all must carry out protocol translation, are mapped in ATM cell and transmit.As everyone knows, the ATM head of 5 bytes can bring to surpass 10% bandwidth loss with respect to the data of 48 bytes, and especially for the packet of long grouping, its packing process is complicated, efficient is very low.And in EPON, although directly carry ethernet frame, implementation procedure is simple, only considers that the line coding of 8B/10B has just had 20% bandwidth waste, adds encapsulation and expense to ethernet frame, and the EPON bandwidth availability ratio is than low 30% left and right of GPON.Simultaneously, when TDM operation transmission, it need to be mapped in ethernet frame by protocol translation, at present this technology also not stipulated unified standard.The GEM of GPON provides a kind of encapsulation of frame structure flexibly, supports the encapsulation of fixed length and random length frame, and multiple business is realized general mapping, do not need to carry out protocol conversion, implementation procedure is simple, and expense is little, protocol encapsulation is most effective reaches 94%, has realized taking full advantage of of bandwidth resources.
(5) powerful OAM ability.For the deficiency of Ethernet system in NM network management and performance monitoring, GPON provides 3 kinds of OAM passages: OAM passage, PLOAM and the OMCI of embedding from the angle of consumer demand and operator's operation maintenance management.They bear different OAM tasks, form C/M Plane (control/management plane), and the different information in the plane manage OAM(Operation Administration Maintenance) separately.During G.983 GPON has also inherited, the OAM related request of regulation, have abundant service management and carrier-class network monitor ability.
(6) technology relative complex, equipment cost is higher.It is to bring take the complexity of technology and equipment as cost to a great extent that GPON carries multi-service that QoS ensures and the powerful advantages such as OAM ability, thereby makes the relevant device cost higher.But along with development and the large-scale application of GPON technology, the cost of GPON equipment may have correspondingly and descend.
