Description

Low noise QSFP transmission line

Technical field

The utility model relates to electronic signal wire rod technical field, the QSFP transmission line that particularly a kind of signal noise is low.

Background technology

QSFP full name Quad Small Form-factor Pluggable (four-way SFP) is a kind of fiber solution, owing to can support the transfer of data of four passages under the port volume that XFP (10Gbps small-sized can plug) is identical with the speed of every path 10 Gbps, namely the transmission speed of QSFP can reach 4 times of XFP product, and speed and density are all better than four-way CX4 interface.

Be enclosed with two strand core groups in common SFP transmission line, comprise two cores in each core group, such structural symmetry is easily held, like this wire rod signal noise is easily controlled, and stereotyped writing core group in QSFP, will be reached, in use symmetry is easily destroyed, and causes signal noise high.

The utility model is exactly the QSFP transmission line in order to provide a kind of signal noise low.

Utility model content

Main purpose of the present utility model is the QSFP transmission line providing a kind of signal noise low.

The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of low noise QSFP transmission line, the outer quilt comprising stereotyped writing core group, be coated on the screen outside described stereotyped writing core group and be coated on outside described screen, core group described in stereotyped writing is divided into the two bursts of core groups be positioned at inside described inner cladding and the six bursts of outer core groups be positioned at outside described inner cladding by an inner cladding, two bursts of described interior core groups are symmetrical compact wrapped in described inner cladding, and six bursts of described outer core group annulars are distributed in outside described inner cladding.

Concrete, described inner cladding is tissue material.

Concrete, each described core group comprises the first aluminium foil layer of two heart yearns, simultaneously wrapped described two heart yearns and wrapped the first wheat outside described first aluminium foil layer is drawn.

Further, described heart yearn comprises conductor and wrapped insulating barrier outside described conductor.

Further, be also provided with a ground wire in described first aluminium foil layer, described ground wire is positioned at two described heart yearn crack sides.

Concrete, described screen comprises that the second wrapped successively from inside to outside wheat is drawn, the second aluminium foil layer and braid.

Compared with prior art, the beneficial effect of the utility model low noise QSFP transmission line is: the compact conformation of this wire rod wire rod, transmission speed can up to 40Gbps, meet the demand of people's data transmission bauds faster, prevent signal noise simultaneously, avoid transmission line bending and extrude the unstable problem of the performance brought.

Numeral in figure:

1-core group, 11-heart yearn, 111-conductor, 112-insulating case, 12-ground wire, 13-first aluminium foil layer, 14-first wheat is drawn, core group in 1a-, the outer core group of 1b-; 2-screen, 21-second wheat is drawn, 22-second aluminium foil layer, 23-braid, the outer quilt of 3-, 4-inner cladding.

Embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.

As shown in Figure 1, a kind of low noise QSFP transmission line of the present utility model, what comprise stereotyped writing core group 1, be coated on the screen 2 outside stereotyped writing core group 1 and be coated on outside screen 2 is outer by 3.Two bursts of symmetries in stereotyped writing core group 1 are compact wrapped in the inner cladding 4 of a tissue material, are defined as interior core group 1a, and all the other six crural ring shapes are distributed in outside inner cladding 4, are defined as outer core group 1b.Inner cladding 4 one aspect makes to keep symmetric position between core group 1a in two strands of inner side, between inner cladding 4 and screen 2 six gangs of outer core group 1b are made to keep relative position on the other hand, therefore this symmetrical configuration degree is high, and symmetry easily keeps, and reduces the generation of signal noise.Because inner cladding 4 is tissue material, therefore there is certain elasticity, the bending action of transmission line can be adapted to and can not damage.

As shown in Figure 1, each core group 1 comprises the first aluminium foil layer 13 of two heart yearns, 11, ground wire 12, simultaneously wrapped two heart yearns 11 and a ground wire 12 and wrapped the first wheat outside the first aluminium foil layer 13 draws 14, and ground wire 12 is positioned at two heart yearn 11 crack sides; Heart yearn 11 comprises conductor 111 and wrapped insulating barrier 112 outside conductor 111.Insulating barrier 112 can avoid each core group 1 of conductor 111 and ground wire 12 in kidney-shaped structure, after transmission line is shaping, supports mutually between core group 1, can not roll, ensure that the stable of structure.First aluminium foil layer 13 plays the shielding action of signal between core group 1.First wheat draws 14 the aluminium foil between adjacent core group 1 can be avoided to contact and wearing and tearing occur and is scattered.

As shown in Figure 1, screen 2 comprises the second wrapped successively from inside to outside wheat and draws the 21, second aluminium foil layer 22 and braid 23.Second aluminium foil layer 22 achieves the outer shield of transmission line.Second wheat is drawn 21 to prevent the first aluminium foil layer 13 and the second aluminium foil layer 22 from contacting with each other to wear and tear.Braid 23 can play shielding action, can reduce wire rod hardness again, facilitates it to bend.

The compact conformation of this wire rod, transmission speed can up to 40Gbps, meets the demand of people's data transmission bauds faster, prevents signal noise simultaneously, avoid transmission line bending and extrude the unstable problem of the performance brought.

Above-described is only execution modes more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection range of the present utility model.
