Description
Technical field
The present invention relates to optical branching device, related in particular to 1 minute 64 and the planar waveguide-type optical branching device of above way.
Background technology
At present worldwide, the mainstream technology that Fiber to the home adopts is the PON(EPON) technology.The PON technology is more a kind of optical fiber access infrastructure to multiple spot in Physical layer (hardware on basis), and wherein (CO) distributes to the luminous power before local distributing frame from the central office, just completed by optical branching device.Optical branching device has two types now: traditional molten planar waveguide-type optical branching device that draws the cone optical branching device and produce based on the optics integrated technology of melting that draws cone coupling mechanism explained hereafter.The fused biconical taper optical branching device is that two or multifiber are tied together, then drawing fusion drawn on the cone machine, and the variation of Real Time Monitoring splitting ratio, splitting ratio finishes fusion drawn after reaching requirement, wherein an end keeps an optical fiber (all the other are cut) as input end, and the other end is made multi-channel output.At present maturation draws cone technique once can only draw 1 minute below 4, and 1 minute device more than 4, after linking together with the device of a plurality of 1 minute 2 again overall package in the optical branching device shell.The molten shortcoming of cone optical branching device of drawing of melting is more, for example: (1) loss is responsive to optical wavelength, generally will select device according to wavelength, this is to cause defective in the three full use procedures of net, because the unification of three nets transmitting optical signal has multi-wavelength's signals such as 1310nm, 1490nm, 1550nm; (2) lack of homogeneity, 4 nominal maximum differed the 1.5dB left and right in 1 minute, differed larger more than 8 in 1 minute, can not guarantee even light splitting, may affect the overall transfer distance.(3) the insertion loss temperature influence changes greatly; (4) increase of more volumes of way is larger, and installing space is restricted, and reliability also reduces simultaneously.The planar waveguide-type optical branching device, it is the light-splitting device that adopts semiconductor technology to make, light is completed on chip along separate routes, the single channel fiber array of coupling package input end and the Multi-channel optical fiber array of output terminal respectively at chip two ends can be realized the nearly light shunt of 1 minute 8,1 minutes 16,1 minutes 32,1 minutes 64 on a chip.
Summary of the invention
1, technical matters to be solved:
1 minute shunt more than 4, loss is long responsive to light, lack of homogeneity, the insertion loss temperature influence is large, and volume is large.
2, technical scheme:
A kind of one minute
64Road waveguide type optical branching device, 64 road chip of light waveguide 11 that comprise 1 minute, single channel fiber array 22 and 64 passage fiber arrays 33, it is characterized in that: 64 road chip of light waveguide 11 were Y type bifurcation structure in 1 minute, the single channel fiber array 22 that is used for the light signal input after its input end adopts UV glue fixing connects, and the 64 passage fiber arrays 33 that are used for light signal output after its output terminal adopts UV glue fixing connect.
For above deficiency, the invention provides
3, beneficial effect:
The present invention has advantages of following: (1) loss is insensitive to optical wavelength transmission, can satisfy unification of three nets to the needs of different wave length transmission; (2) light splitting is even, signal can be distributed to each user equably; (3) structure is small and exquisite, and the directly arrangement and use of existing various cross-connecting boxes need not reserved very large installing space.
