Izimo zokusebenzisa nokwehluka phakathi kwe-Ikhebula le-Coaxial & Ikhebula le-Ethernet

 

 

1. Ikhebula le-Coaxial

 

Ikhebula le-Coaxialsyizintambo ezinomqhubi wethusi ophakathi ogoqwe ngezingqimba zamakhebuli angafakwanga. Kubonakala ngekhono elihle lokulwa nokuphazamiseka, ukudluliswa kwedatha okuzinzile, nentengo ephansi. Ibuye isetshenziswe kabanzi, njengemigqa yethelevishini evaliwe. Izintambo ezincane ze-Coaxial zithengiswa ngama-yuan ambalwa ngemitha emakethe, okungabizi kakhulu. Ikhebula le-coaxial lisetshenziselwa ukuxhuma nenhloko ye-BNC. Ikhebula le-coaxial elithengiswa emakethe imvamisa umkhiqizo ophelile oxhunywe nenhloko ye-BNC. Ungayikhetha ngqo.

 

Kodwa-ke, ngokusho kokuhlaziywa kwezimpawu zekhebula le-coaxial uqobo, ukuncipha kwesiginali lapho idluliswa kukhebula le-coaxial kuhlobene nebanga lokudlulisa nobuningi besiginali uqobo. Ngokuvamile, lapho kuphakama imvamisa yesiginali, kukhulu ukunqanda. I-bandwidth yesiginali yevidiyo inkulu kakhulu, ifinyelela ku-6MHz, futhi ingxenye yombala yesithombe ihlelwe ekugcineni okuphezulu kwemvamisa. Ngale ndlela, lapho isignali yevidiyo idluliswa ngekhebula le-coaxial, hhayi kuphela ubukhulu be-signal jikelele buncishisiwe, kodwa futhi ukunciphisa kwesakhi ngasinye semvamisa kuyahluka kakhulu. , Ikakhulukazi ukunciphisa umbala kungukukhulu kakhulu. Ngakho-ke, izintambo ze-coaxial zilungele kuphela ukudluliswa kwebanga elifushane kwezimpawu zesithombe. Lapho ibanga lokudlulisela lifinyelela cishe kumamitha angama-200, ikhwalithi yesithombe izokwehliswa kakhulu, ikakhulukazi umbala uba mnyama futhi kunomqondo wokuhlanekezelwa.

 

Ekusebenzeni kobunjiniyela, ukuze kunwetshwe ibanga lokudlulisa, i-coaxial amplifier isetshenziswa. Isikhulisi se-coaxial singakhulisa isignali yevidiyo ngezinga elithile, futhi singanxephezela izingxenye ezahlukahlukene zemvamisa ngosayizi abahlukahlukene ngokulungiswa kokulingana, ukuze ukuphazamiseka kokukhishwa kwesiginali yevidiyo ngakwimikhawulo yokwamukela kube kuncane ngangokunokwenzeka. Kodwa-ke, ama-coaxial amplifiers awakwazi ukukhishwa ngokungapheli. Ngokuvamile, ama-coaxial amplifiers ama-2 kuya ku-3 kuphela angafakwa ohlelweni lokukhomba amaphuzu. Ngaphandle kwalokho, ikhwalithi yokudlulisa ividiyo ayinakuqinisekiswa futhi ukulungiswa kunzima. Ngakho-ke, lapho usebenzisa ikhebula le-coaxial ohlelweni lokuqapha, ukuze kuqinisekiswe ikhwalithi yesithombe engcono, ibanga lokudlulisa livame ukukhawulwa cishe amamitha angamakhulu amane noma amahlanu.

 

Ngaphezu kwalokho, izintambo ze-coaxial zisenamaphutha ekudlulisweni kwezimpawu zesithombe ohlelweni lokuqapha:

 

1. Iikhebula le-coaxialuqobo lwayo luthinteka kakhulu ngokushintsha kwesimo sezulu, futhi ikhwalithi yesithombe iyathinteka ngezinga elithile;

 

2. The ikhebula le-coaxial is thicker, and wiring is not convenient for dense monitoring applications;

 

3. Ikhebula le-Coaxials generally can only transmit video signals. If the system needs to transmit control data, audio and other signals at the same time, additional wiring is required;

 

4. Ikhebula le-Coaxial has limited anti-interference ability and cannot be used in strong interference environment;

 

5. I-coaxial amplifier nayo inenkinga yobunzima ekulungiseni.

 

II Tumbhangqwana onengilimbi

 

Commonly used tumbhangqwana onengilimbi cuyakwazis are IKATI5 Cuyakwazis and IKATI5E Cuyakwazis, IKATI6 Cuyakwazis, and IKATI7 Cuyakwazis. The former has a thin cuyakwazi diameter and the latter has a thick cuyakwazi diameter. The models are as follows:

 

1.IKATI5Eikhebula:Lolu hlobo lwentambo lukhuphukile ukuminyana, i-high quality material, kanye nezinga lokudlulisa le-100MHz. Isetshenziselwa ukudluliswa kwezwi nokudluliswa kwedatha ngezinga eliphezulu lokudlulisa elingu-100Mbps. Isetshenziselwa ikakhulukazi inethiwekhi ye-100BASE-T ne-10BASE-T. Lezi yizintambo ze-Ethernet ezisetshenziswa kakhulu.

 

2.IKATI5E:

IKATI5E has low attenuation, less crosstalk, higher attenuation-to-crosstalk ratio (ACR), signal-to-noise ratio (Structural Return Loss), smaller delay error, and performance Greatly improved. The maximum transmission rate of Super IKATI5ikhebula is 250Mbps.

 

3. IKATI6 Cuyakwazi: The transmission frequency of this type of cuyakwazi is 1MHz~250MHz. The comprehensive attenuation crosstalk ratio (PS-ACR) of IKATI6 wiring system should have a large margin at 200MHz, which provides 2 times that of IKATI5 bandwidth. The transmission performance of IKATI6 cabling is much higher than that of the Super IKATI5 standard, and is most suituyakwazi for applications with a transmission rate higher than 1Gbps.

An important difference between IKATI6 and IKATI5 is that it improves the crosstalk and return loss performance. For the new generation of full-duplex high-speed network applications, excellent return loss performance is extremely important. The basic link model is cancelled in the six types of standards. The wiring standard adopts a star-shaped topology. The required wiring distance is: the length of the permanent link cannot exceed 90m, and the channel length cannot exceed 100m.

 

4. IKATI6E cuyakwazi: The IKATI6Eikhebula is an improved version of the IKATI6Eikhebula, which is also an unshielded tumbhangqwana onengilimbi cuyakwazi specified in ANSI/EIA/TIA-568B.2 and ISO IKATI6/Class E standards. Mainly used in gigabit networks. In terms of transmission frequency, it is also 200-250 MHz like IKATI6 lines, and the maximum transmission speed can also reach 1 000 Mbps, but it is greatly improved in terms of crosstalk, attenuation and signal-to-noise ratio.

 

IKATI 5 and VII cuyakwazi: This cuyakwazi is the latest tumbhangqwana onengilimbi in the ISO 7/F standard. It is mainly used to adapt to the application and development of 10 Gigabit Ethernet technology. But it is no longer an unshielded tumbhangqwana onengilimbi, but a shielded tumbhangqwana onengilimbi, so its transmission frequency can reach at least 500 MHz, which is more than twice that of IKATI6 and IKATI6Eikhebulas. Up to 10 Gbps.
