Description
Technical field
The invention belongs to communication cable technical field, more particularly to a kind of high speed optoelectronic composite cable.
Background technology
At present, surpass five class cables (CAT5E) have decay it is small, crosstalk is few, and with higher decay and crosstalk ratio and
The smaller delay inequality of signal to noise ratio, performance obtain bigger raising.This surpasses five class cables and is mainly used in GBIC (1000Mbps),
Its unshielded twisted pair (UTP) basic structure is：24AWG*4P+ tear-proof rope fill, but each pair lay its balance section design more
Precision, lay design more exquisite precision.
The transmission frequency of six class cables (CAT6) is 1MHZ-250MHZ, and the six classes cable wiring system integrates in 200MHZ to decline
Subtracting crosstalk ratio has larger surplus, it is possible to provide 2 times of bandwidth for surpassing five classes, its transmission performance significantly larger than surpass five class standards, are adapted to
Transmission rate is higher than 1Gbps application.Six classes are to improve in crosstalk and echo with surpassing an important difference of five classes
Performance in terms of loss, for the highspeed network applications of full duplex of new generation, excellent return loss performance is of the utmost importance
Transmission objective.Basic link model is eliminated in six class standard, line standard opens up benefit structure using star, it is desirable to cloth line-spacing
From for：Permanent link length is less than 90 meters, and channel length is less than 100 meters.Its UTP basic structure is：24AWG*4P+ tear-proof ropes
Filling, but each pair lay its balance section design becomes more meticulous, and lay design is smaller, and insulation line footpath concentricity requirement is higher, and line footpath is public
Difference and characteristic impedance control are tighter.
Surpass the upgrade version that six class cables (CAT6E) are six class lines, be equally ANSI/EIA/TIA-568B.2 and ISO6 classes/E levels
A kind of utp cable, is mainly used in giga-bit network specified in standard.In terms of transmission frequency with six classes
Cable is the same, is 200-250MHZ, and peak transfer rate can reach 1000Mbps, simply in crosstalk, decay and signal to noise ratio etc.
There is larger improvement；Another feature is to have added 1 criss-cross line between 4 twisted-pair feeders pair to divider.Without ten splittings of words, line
A pair of lines in cable may sink into the gap between two wires of another pair line, and the spacing between line pair reduces and aggravates crosstalk and ask
Topic.4 pairs of wires are tightly held in the position of its design by divider together with the crust of cable simultaneously, and it is curved to slow down cable
The line rolled over and brought reduces the reduction of performance when installing to loose, and its UTP basic structure is：24AWG*4P+ physical blowings
Divider integral type is filled, and increases overall cable function.
Seven class cables (CAT7) are a kind of twisted-pair feeders newest in ISO7 classes/F level standards, predominantly adapt to ten thousand megabits of Ethernets
The application and development of technology.But it is no longer a kind of unshielded twisted pair, but a kind of Shielded Twisted Pair, can be provided at least
500MHZ overall attenuation to crosstalk than and 600MHZ overall bandwidth, be six class cables and surpass more than 2 times of six class cables, transmission speed
Rate is up to 10Gbps.In seven class cables, every a pair of lines have a screen layer, and four pairs of lines are combined a shared public large-size screen monitors
Cover layer.From physically, extra screen layer make it that seven class cable footpaths are larger and enhances the ability of its connection hardware, seven
The parameter request connector of the class system line all in 600MHZ is to providing at least 60dB ponver sum next.And surpass five classes
System is only required provides 43dB in 100MHZ, and six class system requirements are 46dB in 250MHZ numerical value, its UTP basic structure
It is：(24AWG*1P+ single pair double focusing fat band+hot type technique hot-melt type plastic-aluminum shielding) * 4+ aluminum plastic belts shielding+ground wire+metal is total
Shielding.
Eight class cables (CAT8) have related definition in the world at present, but the SIEMON companies in the U.S. have announced to have developed eight classes
Cable, the eight classes cable network possess 2000MHZ bandwidth, it is possible to provide multiple function services, can handle TERRESTRIAL TV
CCTV DAB FM audio, IR controls, 10/100/1000M Ethernets, video, phone, USB peripheral device etc..The eight classes cable produces
Product are to become more meticulous shield type twist paired signal line to structure design, and often proximally and distally cross-talk interferes with each other signal, declined between line pair
Subtract crosstalk ratio, return loss and the serious presence of SRL structural return loss, do not form complete closure transmission state；In pair twist and cabling process
Upper control characteristic impedance and decay difficulty are too big, can not be broken through in master-plan and disturb bottleneck by technique electromagnetic pulse-resisting；
Transmission bandwidth is only limitted to 2000MHZ, can not break through to 2500-3000MHZ bandwidth, and design and select material can not lift function and reach more
High-transmission effect；Its extrusion process cost that insulate is higher, identifies that cost is too high for insulation color separation, note bar color cored wire often because
It is whole that note bar insulation material and major ingredient isolation material priority compatibility cause Concentricity tolerance, the increasing of line footpath deviation probability to directly influence
The characteristic impedance of bar cable controls difficulty and laser propagation effect；Common mode lotus root is closed and resisted in extraneous EMC effects effectively preventing shielding
Still suffer from compared with big limitation, and can not be designed and be broken through by line body structure.
