Description
Technical field
The present invention relates to the technical field of fiber broadband access network, more particularly to one kind realizes that active/standby light path is intelligently cut
The optical transmitter protection system changed.
Background technology
It is the letter to be transmitted by the envelope of modulated carriers by modulates information to carrier wave that traditional broadcast television network is
Number, the carrier frequency modulated is transmitted on conductor, and conductor can be wire rope, optical cable etc., and medium when being wirelessly transferred is air.
Distribution mechanism is passive distribution, is power distribution, rather than bandwidth allocation.So originator is equal to bandwidth of registering one's residence.Due to originator
Had an agreement with receiving end.On modulates information to the frequency for providing, receiving end is received originator by the frequency of regulation, and is demodulated solution
Code can obtain desired information, and receiving terminal under any application without receiving originating terminal signal.But legacy network exist with
Lower Railway Project：1st, influenceed by spacing wireless channel, physical channel number is much smaller than planning channel number；2nd, because the band planned is a width of
1000M, bandwidth demand cannot be met when the later stage is to high definition or 3D Polarizations for Target Discrimination in Clutter；3rd, it is cable system below photoreceiver, radio frequency refers to
Target influence is larger.
Analysis and optimization to legacy network, IP data transfers include unicast, broadcast and multicast, need to realize networking
Simplification, standardization, IPization and passive.IPization is carried out to the broadcast television signal to be transmitted, but does not use the unicast of IPTV
Or multicast mode, but the transmission of cable tv broadcast pattern is still pressed to the broadcast television signal of IPization.It is right under the conditions of optical-fiber network
IPization broadcast television signal cancels the modulation /demodulation link of original Coaxial Network cable television delivery systems electric signal layer, wide to IPization
Broadcasting TV signal carries out direct broadcast transmission.So as to develop and retain the broadcast characteristic of cable TV network, direct broadcast band
Broadcast still retain broadcast capability.In terminal receiver, a circuit is researched and developed, equivalent to original cable television receiver terminal
Tuner, select user to want the broadcast TV program seen in IP broadcast TV signal.
(Fiber to the Building, referred to as " FTTB ") and fiber-to-the-home (Fiber to because Fiber To The Building
The Home, referred to as " FTTH ") network be all framework on optical networking, the reliability of light net just becomes whole system reliability
The premise of property.And the maximally effective two schemes one of raising or guarantee light net reliability are Optical Cables, two is the 1 of the network equipment
+ 1 redundancy backup.The 1+1 redundancy backups scheme of equipment is then that part occurs in failure, is realized by handoff technique.
