Whether it's fiber optic patch cords used to connect between fiber optic patch panels and switches in a data center, or copper patch cords used in local area networks to connect end devices to work area outlets, patch cords are integral to the network An integral part of the network, and the jumper is often the most vulnerable link in the network. It is more susceptible to damage than any other part.
Qurilmaning o'tish moslamalari eng zaif qismlar bo'lganligi sababli, kanal sinovi ko'proq joy beradi. Bu shuni anglatadiki, agar yuqori sifatli uskuna yamoq kabellari ishlatilsa, doimiy havola muvaffaqiyatsiz bo'lsa ham kanal sinovidan o'tishi mumkin. Uskunaning yamoq shnurlari va asbob-uskunalarning harakatlanishi potentsialini hisobga olgan holda, kanalning sobit qismini oldindan bilish muhimdir.
Equipment patch cords are not included in the front-end permanent link test, but that doesn't mean they should be ignored. Once the fixed part of the network is installed and tested, subsequent channel testing can identify problems with equipment patch cords, especially if your customers are having problems with damaged or substandard equipment patch cords.

To understand the quality of equipment patch cords, the Communications Cable Association completed large{{0}}scale electrical performance testing of Category 6 copper patch cords, testing nearly 500 samples, including 379 patch cords from lesser-known manufacturers and 120 from well-known North American Manufacturer's jumper. Of the 379 marine patch cords, 322 did not meet the electrical performance parameters specified in the TIA 568-C.2 standard, 78 percent did not meet 3dB or more, and 45 percent did not meet 6dB or more. These jumpers, once included in the channel, can cause serious network problems. All patch cords from recognized manufacturers in North America have a 0 percent failure rate.
Fiber patch cord sifati testi
FOCC muhandislari 4 ta mahalliy va xorijdagi universal yig'ish zavodlaridan onlayn chakana sotuvchilardan sotib olingan universal optik tolali patch shnurlarni, shuningdek, 5 ta taniqli brendlarning yamoq simlarini sinovdan o'tkazdilar: 9 ta turli yetkazib beruvchilarning 36 ta optik tolali patch kabellari ikkita spetsifikatsiya yordamida sinovdan o'tkazildi Tasodifiy dupleks LC multimode patch shnur namunalari kiritish yo'qolishi va qaytish yo'qolishi uchun sinovdan o'tkazildi. ISO/IEC va TIA sanoat standarti qattiq ichki spetsifikatsiyalari bilan 0.25dB kiritish yoʻqolishi va 30dB qaytish yoʻqolishi. Faqat bitta umumiy yetkazib beruvchi barcha spetsifikatsiyalardan o'tdi. Bundan tashqari, barcha umumiy namunalar oxirgi yuz geometriyasining uchta asosiy parametridan kamida ikkitasini bajara olmadi va ishlash testida mexanik ishonchlilikning barcha to'rtta parametrini (ya'ni, kabelni tortib olish, egilish, burish va ushlab turish) muvaffaqiyatsiz tugadi.
FOCC muhandislari sinovning ikkinchi bosqichini ham o'tkazdilar, ammo yuqori tezlikda 40 va 100 Gig ilovalari uchun yangi maksimal chiqish konnektorlarini ko'rib chiqdilar. Shunga qaramay, qo'shishni yo'qotish va qaytarish yo'qotish uchun sanoat va ichki spetsifikatsiyalardan o'tadigan faqat bitta umumiy komponent mavjud.

Xaridorlar ehtiyot bo'ling! Qurilma jumperi sotib olingan kanal ishlashga sezilarli ta'sir ko'rsatishi mumkin. Agar arzon umumiy variant tarmoqning uzilishlari va uzatish muammolariga sabab bo'lsa, uzoq muddatda muammoni hal qilish uchun ko'proq pul kerak bo'ladi.

Yamoq simlari va patch shnurlari bilan bog'liq muammolarni aniqlash uchun qurilma joyiga yamalgandan so'ng kanal sinovini o'tkazishdan tashqari, yamoq shnurlari va patch shnurlarini alohida-alohida sinab ko'rish va yamoq shnurlaridan namuna olishni sinab ko'rish ham yaxshi amaliyotdir, ayniqsa siz ushbu tarmoqdan bo'lsangiz. simi zavodida boshqa etkazib beruvchilardan turli sotuvchi o'tish kabellari.
Fluke Networks' DSX series like the DSX2-5000 CH Patch Cord Test Adapter can be used to test Category 5e, 6 and 6A copper patch cords. These adapters include RJ45 plug terminations and are patch cord certified according to TIA-568-C.2 and IEC 61935-2 standards.
When it comes to fiber patch cords, testing is like testing any fiber optic cable with an Optical Loss Tester (OLTS) like Fluke Networks' CFP Fiber Tester. Simply set up the reference using the single jumper reference method and use the adapter to connect the jumper to the test reference lead. When connecting the other end of the jumper to the remote unit, only test the connection loss between the reference wire and the jumper. Simply reverse the jumper wire to test the connector on the other end.
Fluke FI-7000 InspectorPro kabi mikroskop yoki inspeksiya sinov qurilmasidan tolali patch shnuri uchlarining ifloslanishi va tozaligini tekshirish uchun moʻljallangan.
