300pinMSA是完備的光接口模塊，其特點(diǎn)是體積大，用散熱器型金屬外殼封裝，以利于散熱。該類型光模塊支持10Gbps和40Gbps兩種規(guī)格。這兩種規(guī)格的光模塊電接口都工作在16個(gè)并行信道上，10G規(guī)格模塊的單信道電接口速率為622~669MHz，符合OFI的SFI4和IEEE的XSBI規(guī)范。40G規(guī)格模塊的單信道電接口速率為2.5G~3.125G，符合SFI5規(guī)范。該類光模塊支持SONET/SDH和10GXSBI。遵循ITU-TG.691和G.693標(biāo)準(zhǔn)，傳輸距離從600m到80km。廣州QSFP加工單模光纖的尺寸為9-10/125μm，并且較之多模光纖具有無限量帶寬和更低損耗的特性。</p><div

切削：切削工藝的具體種類很多，從無潤(rùn)滑切削到潤(rùn)滑切削，從高速切削到激光切割，從車、鉆到銑、磨，在散熱片的成形過程中，為了獲得一些較特殊、精細(xì)的形狀，都需要使用切削工藝。具體用途主要有板材（吸熱底、鰭片等）成形、散熱片開槽、底面修整、特殊雕刻等。優(yōu)勢(shì)：根據(jù)不同方式、刀具，可適用于各種用途。劣勢(shì)：設(shè)備，主要是刀具磨損快，多數(shù)需要人工參與或自動(dòng)化控制，成本高。鋁擠壓：鋁擠壓技術(shù)簡(jiǎn)單的說就是將鋁錠高溫加熱至約520~540℃，在高壓下讓鋁液流經(jīng)具有溝槽的擠型模具，作出散熱片初胚，然再對(duì)散熱片初胚進(jìn)行裁剪、剖溝等處理后就做成了我們常見到的散熱片。鋁擠壓技術(shù)較易實(shí)現(xiàn)，且設(shè)備成本相對(duì)較低，也使其在前些年的低端市場(chǎng)得到普遍的應(yīng)用。一般常用的鋁擠型材料為Al6063，其具有良好熱傳導(dǎo)率(約160~180W/m.K)與加工性。不過由于受到本身材質(zhì)的限制散熱鰭片的厚度和長(zhǎng)度之比不能超過1：18，所以在有限的空間內(nèi)很難提高散熱面積，故鋁擠散熱片散熱效果比較差。 </p> <p> <br /> 事實(shí)上，只要LED指示燈變綠，即為連通狀態(tài);否則，說明連接跳線或開關(guān)按鈕有問題.東莞芯片SFP價(jià)格</p><p style="text-indent:25px">多模光端機(jī)通過多模光纖可進(jìn)行長(zhǎng)達(dá)5公里的傳輸，以發(fā)光二極管或激光器為光源。廣州QSFP加工</p><p> 鋁散熱器的優(yōu)點(diǎn)： </p> <p> 1、鋁合金材料具有重量輕的特點(diǎn)，便于安裝和搬運(yùn)。在散熱量相同時(shí)，其重量只有鑄鐵散熱器的十一分之一、鋼質(zhì)散熱器的六分之一、銅質(zhì)散熱器的三分之一。 </p> <p> 2、安裝簡(jiǎn)單、維修方便。由于鋁合金密度小，而且可以加工成各種形狀與規(guī)格的零部件，所以該種鋁型材散熱器的截面大而規(guī)整，產(chǎn)品組裝、表面處理可一步到位，施工現(xiàn)場(chǎng)可直接安裝，節(jié)省大量安裝費(fèi)用。維修也方便，費(fèi)用低廉。 </p> <p> 3、節(jié)能降耗、使用成本低。當(dāng)散熱器進(jìn)出口中心距和熱傳導(dǎo)溫度相同時(shí)，鋁型材散熱器比鑄鐵散熱器的散熱量高出2.5倍，又因外形美觀，可不加暖氣罩，可減少熱損失30%以上，成本降低10%以上，鋁型材熱器的散熱效果雖然稍遜于銅質(zhì)散熱器，但重量可減輕。由于鋁價(jià)只有銅價(jià)的1/3，因此，可降低成本。 </p> <p> <br />
