The device comprises a ring-type optical communication line (100), a CO (200), and a plurality of remote nodes (RN) (300). According to the utility model, the advantages of the device are as follows: various types of losses, which include the insertion loss caused by connection of various devices with the ring-type optical communication line as well as the loss caused by cable aging and are caused by various environmental factors, are compensated properly, so that the quality and stability of the communication are improved.
Description
Technical field
The present invention relates to a kind of Wavelenght division multiplexing passive optical network system and how ring-like Wavelenght division multiplexing passive optical network system, with the core component of this Wavelenght division multiplexing passive optical network system as three-network integration system
Background technology
Wavelength division multiplexing (WDM) is to specify different wave length and send the method for data simultaneously for each user.Each user can use institute's assigned wavelength to send always or receive data.The advantage of this method is and can sends Large Volume Data to each user that the fail safe of communication is fine, and is easy to improve performance.
Simultaneously, the passive optical network (PON) as a kind of method that Fiber to the home (FTTH) of structure is that one of them optical line terminal (OLT) can use the passive optical distribution apparatus to connect the method for a plurality of optical network units (ONU) on single optical cable.In PON, by single optical fiber data are sent to remote node (RN) from C0, data are cut apart by the passive optical distribution apparatus of RN, and send to each user by independent optical fiber then.That is to say, PON has following configuration, and wherein C0 is connected to the RN that is installed near the position user via single optical fiber, and RN is connected to each user via independent optical fiber, thereby compare with the situation of the independent optical fiber of installation along the line from C0 to the user, the optical cable cost can reduce.
Summary of the invention
Can combine and realize a kind of three-network integration system equipment by above-mentioned WDM being draped over one's shoulders art and PON technology.This system adopts the redundancy structure with redundant component to substitute cutting optical fiber, defective laser diode (LD usually; Corresponding to the light transmitting element) or defective photodiode (PD; Corresponding to light receiving unit).
A kind of three-network integration system equipment based on light wavelength division multiplexing comprises: power module, the defective laser diode LD, unicast data, defective photodiode PD, controller CPU, main channel, dependent channel, intermediate buffering, 100Base-TX, by single optical fiber data are sent to remote node (RN), data are cut apart by the passive optical distribution apparatus of RN, and send by independent optical fiber then.
Described three-network integration system equipment comprises ring-like optical communication line 100, C0200 and a plurality of RN300.C0200 is connected to a plurality of RN300 by ring-like optical communication line 100.
C0200 comprises multiplexer/demultiplexer 230, carry out multiplexed to the wavelength optical signals that receives by the light circulator of describing after a while 240, and export multiplexed light signal then to optical communication line 100, and the multiplexed light signal that receives by optical communication line 100 is carried out multichannel separate, export light signal after multichannel is separated then to light circulator 240.
The advantage of this system is can not wrap error of transmission in low-rate data transmission or high speed data transfers.
The present invention to can adequate compensation because the WDM PON system of the loss that various environmental factors cause is studied, described loss is for example for being connected various device the loss that the insertion loss that causes and optical cable wear out and cause with ring-like optical communication line.
Described how ring-like WDM PON system not only can use identical systems to hold more users by a plurality of ring-like optical communication line in the three-network integration system equipment that adopts the prior art of submitting to based on the present patent application people, and can adequate compensation because the loss that various environmental factors cause, for example various device is connected the loss that the insertion loss that causes and optical cable wear out and cause with ring-like optical communication line.
The present invention is conceived to solve the problems of the technologies described above, and a target of the present invention provides a kind of three-network integration system equipment, described system can adequate compensation because various types of losses that various environmental factors cause, for example various device is connected the loss that the insertion loss that causes and optical cable wear out and cause with ring-like optical communication line.
The advantage of three-network integration system equipment of the present invention is by adequate compensation because various types of losses that various environmental factors cause, for example various device is connected the insertion loss and the aging loss that causes of optical cable that cause with ring-like optical communication line, can improves the quality and the stability of communication.
