آموزش تصویری ساخت کابل شبکه کراس و مستقیم cross & Straight Ethernet cables

برای اتصال دو یا چند کامپیوتر  هم نیاز به استفاده از نوع های مختلف کابل اترنت است.cat5 نمونه ای رایج در ارتباطات شبکه ای است که در بسیاری از خانه ها و شرکت ها مورد استفاده قرار می گیرد. Category 5 cable برای عاملیت اصلی ۱۰/۱۰۰ مورد استفاده قرار می یگرد و CAT 5e برای gigabit (1000BaseT) operation .
1- کابل Ethernet برای مسافت کمتر از ۹۶ متر استفاده می شودو در صورت خواستن مسیر بیشتر از repeater و یا یک سوییچ می شود این کمبود انتقال داده را جبران کرد.

۲- یک جفت سوکت RJ-45 که همان سر کابلی RJ-45 می باشد.RJ مخفف Registered Jack است.

۳- یک Crimper برای محکم کردن سر RJ-45

4- سیم چین برای بریدن قسمت های اضافه ی سیم Wire Cutters

5- سیم لخت کن برای مواقع لازم Wire Stripper
6- یک Cable Tester برای تست سالم بودن کابل که البته با ۲ کامپیوتر هم می شود این کار را انجام داد.

نحوه ی بستن کابل :
ابتدا کابل خود را با استفاده از Crimper و یا سیم لخت کن ، لخت کنید و در این صورت ۴ جفت سیم به هم تابیده شده ملاحظه می فرمایید.که رنگهای آنها با هم متفاوت است.

Step 2a picture

حال ۴ جفت را از یکدیگر تفکیک کنید تا رنگ ها مشخص شود.۸ رنگ در این کابل ها وجود دارد که به صورت جفتی به هم تابیده شده اند.که ۴ تا آنها رنگی و ۴ تای دیگر ترکیب سفید و رنگ کابل تابیده شده به آن را دارند.(در بعضی از کابل های موجود در بازار سیم ترکیب سفید و رنگ سیم تابیده شده نیست و فقط سفید است که تشخیص آن با سیم تابیده شده است)
برای مثال سیم نارنجی و سفید/نارنجی به هم تابیده شده اند.علت تابیده شدن این سیم ها به دور هم،جلوگیری از نویز و پارازیت می باشد.

Step 3 picture

آنها را کنار هم طبق قوانین زیر قرار دهید و قسمت زیادی را با استفاده از سیم چین ببرید.چون اگر زیاد باشد ممکن است روکش در داخل سوکت جا نگید مقداری زدگی در بیرون به وجود اید که امکان قطع شدن سیم ها و امنیت آنها را پایین می آورد.

استاندارد AT&T به دو صورت T568A و T568B برای بستن این سیم ها و قراردادن در RJ-45 است.که ۲ نوع کابل کراس(CROSS) و مستقیم (STRAGHT) را به وجود می آورد.اگر هر ۲ سر CONNECTOR های RJ-45 به صورت Aو یا B باشد به این نوع کابل مستقیم می گویندو اگر یکی از آنها A و دیگری B باشد به آن کابل CROSS می گویند.

در صورتی که بخواهید ۲ کامپیوتر را مستقیما به هم وصل کنید از کابل Cross استفاده می شود(البته از کابل مستقیم هم می شود استفاده کرد اما ارتباط یک طرفه است و فقط یک کامپیوتر امکان فعالیت بر دیگری را دارد.)


Crossover cable use

و در صورتی که یک شبکه ی lan داشته باشیم و کامپیوترها را بخواهیم به سوییچ وصل کنیم از کابل مستقیم یا straight استفاده می شود.


‘Straight Through’ cable use

ترتیب رنگ ها به صورت استاندارد :
white/orange, orange, white/green, blue, white/blue, green, white/brown, brown
است که این مصداق ۵۶۸B می باشد.که شامل سفید/نارنجی،نارنجی،سفید/سبز،آبی،سفید/آبی، سبز،سفید قهوه ای و قهوه ای می باشد.
همان طوری که در شکل های زیر مشاهده می کنید از ۸ سیم موجود ۴ تای آنها استفاده نمی شود و فقط ۴ تای آنها برای دریافت و ارسال به صورت مثبت ومنفی به هم وصل می شوند.

Ethernet Pinout

استاندارد ۵۶۸A به صورت : سفید/سبز،سبز،سفید/نارنجی،سفید/قهوه ای ،قهوه ای،نارنجی،آبی،سفید/آبی ** می باشد.

شکل بالا نحوه ی زدن کابل کراس و مستقیم و نحوه ی اتصال قطب های مختلف مثبت و منفی و سیم هایی که استفاده نمی شوند و در این حالت اهمیت ندارند را نشان می دهد.

پس از وارد کردن سیم ها بر مبنای مورد نظر به داخل RJ45 end باید با استفاده از Crimper آن را به اصطلاح crimp کنیم تا در جای خود سفت شود.

IMG_1105

پس از بستن آن با دستگاه cable tester کابل خود را تست کنید و یا یک سر آن را به داخل کارت شبکه ی یک pc و سر دیگر آن را به داخل کارت شبکه ی pc دیگر زده ،باید چراغ لینک روشن شود که معمولا به رنگ سبز و یا قرمز است.

IMG_1106

کار تمام است و حال شما می توانید این کابل را در ارتباطات اینترنتی خود و یا اتصال به مودم و یا به صورت مستقیم به کامپیوتر دیگری اتصال بدهید.

 

موفق و پیروز باشید ...
