簡單的說，光模塊的作用就是光電轉(zhuǎn)換，發(fā)送端把電信號轉(zhuǎn)換成光信號，通過光纖傳送后，接收端再把光信號轉(zhuǎn)換成電信號。 </p> <p> 2、光模塊的種類/類型/分類： </p> <p> 按速率分類：百兆光模塊、千兆光模塊、10G光模塊、40G光模塊、100G光模塊。 </p> <p> 按封裝分類：SFP光模塊、SFP+光模塊、XFP光模塊、QSFP+光模塊、CFP光模塊、QSFP28光模塊、CXP光模塊、X2光模塊、XENPAK光模塊。 </p> <p> 按模式分類：單模光模塊和多模光模塊。 </p> <p> <br /> </p><p> 就散熱片材質(zhì)來說，每種材料其導(dǎo)熱性能是不同的，按導(dǎo)熱性能從高到低排列，分別是銀，銅，鋁，鋼。不過如果用銀來作散熱片會太昂貴，故比較好的方案為采用銅質(zhì)。雖然鋁便宜得多，但顯然導(dǎo)熱性就不如銅好(大約只有銅的50%左右)。 </p> <p> 目前常用的散熱片材質(zhì)是銅和鋁合金，二者各有其優(yōu)缺點。銅的導(dǎo)熱性好，但價格較貴，加工難度較高，重量過大(很多純銅散熱器都超過了CPU對重量的限制)，熱容量較小，而且容易氧化。而純鋁太軟，不能直接使用，都是使用的鋁合金才能提供足夠的硬度，鋁合金的優(yōu)點是價格低廉，重量輕，但導(dǎo)熱性比銅就要差很多。有些散熱器就各取所長，在鋁合金散熱器底座上嵌入一片銅板。 </p> <p> 對于普通用戶而言，用鋁材散熱片已經(jīng)足以達(dá)到散熱需求了。 </p> <p> 北方冬季取暖的暖氣片也叫散熱片。 </p> <p> 散熱片在散熱器的構(gòu)成中占有重要的角色，除風(fēng)扇的主動散熱以外，評定一個散熱器的好壞，很大程度上取決于散熱片本身的吸熱能力和熱傳導(dǎo)能力。 </p> <p> <br /> </p> <p> <br /> 光纖跳線的類型與芯徑必須與布線中使用的光纖完全相同。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="茂名5G基站SFP供應(yīng)商,SFP"

style="text-indent:25px">小型散熱器(或稱散熱片)由鋁合金板料經(jīng)沖壓工藝及表面處理制成，而大型散熱器由鋁合金擠壓形成型材，再經(jīng)機(jī)械加工及表面處理制成。它們有各種形狀及尺寸供不同器件安裝及不同功耗的器件選用。散熱器一般是標(biāo)準(zhǔn)件，也可提供型材，由用戶根據(jù)要求切割成一定長度而制成非標(biāo)準(zhǔn)的散熱器。散熱器的表面處理有電泳涂漆或黑色氧極化處理，其目的是提高散熱效率及絕緣性能。在自然冷卻下可提高1015%，在通風(fēng)冷卻下可提高3%，電泳涂漆可耐壓500800V。散熱器廠家對不同型號的散熱器給出熱阻值或給出有關(guān)曲線，并且給出在不同散熱條件下的不同熱阻值。多模光端機(jī)通過多模光纖可進(jìn)行長達(dá)5公里的傳輸，以發(fā)光二極管或激光器為光源。東莞通訊SFP光模塊散熱片</p><p

壓固法也就是將眾多的銅片或鋁片疊加起來，然后在兩側(cè)加壓并將其截面進(jìn)行拋光，這個截面與CPU主要接觸，另外一面則伸展開來作為散熱片的鰭片。壓固法制作的散熱器其特點是鰭片數(shù)量可以做的很多，而且不需要很高的工藝就能保證每個鰭片都能與CPU主要保持良好的接觸（或靠近），而各個鰭片之間也通過壓固的方式有著緊密的接觸，彼此之間的熱量傳導(dǎo)損失也會明顯降低，正是因為壓固法制作的散熱器擁有眾多的鰭片，這種散熱器的散熱效果往往不錯，重量則比傳統(tǒng)的散熱器要輕的多。 </p> <p> 鍛造式散熱片鍛造工藝就是將鋁塊加熱后利用高壓充滿模具內(nèi)而形成的，它的優(yōu)點是鰭片高度可以達(dá)到50mm以上，厚度1mm以下，能夠在相同的體積內(nèi)得到比較大的散熱面積，而且鍛造容易得到很好的尺寸精度和表面光潔度。但鍛造時，因金屬的塑性低，變形時易產(chǎn)生開裂，變形抗力大，需要大噸（500噸以上）位的鍛壓機(jī)械，也正因為設(shè)備和模具的高昂費(fèi)用而導(dǎo)致產(chǎn)品成本極高，連許多超頻發(fā)燒友都無福消受。
