信息凈負(fù)荷位于STM-N幀中第1到第9行，第9×N+1到第270×N列，寧夏SDH設(shè)備烽火RET，共9×261×N個(gè)字節(jié)。信息凈負(fù)荷是在STM-N幀結(jié)構(gòu)中存放將由STM-N傳送的各種用戶信息碼塊的地方。 </p> <p> 為了實(shí)時(shí)監(jiān)測(cè)貨物（打包的低速信號(hào)）在傳輸過(guò)程中是否有損壞，在將低速信號(hào)打包的過(guò)程中加入了通道開銷（POH）字節(jié)。POH作為凈負(fù)荷的一部分與信息碼塊一起裝載在STM-N這輛貨車上在SDH網(wǎng)中傳送，它負(fù)責(zé)對(duì)打包的貨物（低速信號(hào)）進(jìn)行通道性能監(jiān)視、管理和控制。 </p> <p> 2、段開銷（SOH） </p> <p> 段，相當(dāng)于一條大的傳輸通道，段開銷是為了保證信息凈負(fù)荷正常傳送所必須附加的網(wǎng)絡(luò)運(yùn)行、管理和維護(hù)（OAM）字節(jié)。也就是說(shuō)SOH完成對(duì)貨物整體的監(jiān)控，POH是完成對(duì)某一件特定的貨物進(jìn)行監(jiān)控，當(dāng)然，SOH和POH還有一些其他管理功能，寧夏SDH設(shè)備烽火RET。 </p> <p> 段開銷又分為再生段開銷（RSOH）和復(fù)用段開銷（MSOH），可分別對(duì)相應(yīng)的段層進(jìn)行監(jiān)控，二者的區(qū)別在于監(jiān)管的范圍不同，寧夏SDH設(shè)備烽火RET。 </p> <p> 3、管理單元指針（AU-PTR） </p> <p> 管理單元指針位于STM-N幀中第4行的***到第9×N列，共9×N個(gè)字節(jié)。AU-PTR是用來(lái)指示信息凈負(fù)荷的***個(gè)字節(jié)在STM-N幀內(nèi)的準(zhǔn)確位置的指示符，以便接收端能根據(jù)這個(gè)位置指示符的值（指針值）準(zhǔn)確分離信息凈負(fù)荷。終端復(fù)用器用在網(wǎng)絡(luò)的終端站點(diǎn)上。寧夏SDH設(shè)備烽火RET</p><div

SDH的應(yīng)用 </p> <p> 由于以上所述的SDH的眾多特性，使其在廣域網(wǎng)領(lǐng)域和**網(wǎng)領(lǐng)域得到了巨大的發(fā)展。中國(guó)移動(dòng)、電信、聯(lián)通、廣電等電信運(yùn)營(yíng)商都已經(jīng)大規(guī)模建設(shè)了基于SDH的骨干光傳輸網(wǎng)絡(luò)。利用大容量的SDH環(huán)路承載IP業(yè)務(wù)、ATM業(yè)務(wù)或直接以租用電路的方式出租給企、事業(yè)單位。而一些大型的**網(wǎng)絡(luò)也采用了SDH技術(shù)，架設(shè)系統(tǒng)內(nèi)部的SDH光環(huán)路，以承載各種業(yè)務(wù)。比如電力系統(tǒng)，就利用SDH環(huán)路承載內(nèi)部的數(shù)據(jù)、遠(yuǎn)控、視頻、語(yǔ)音等業(yè)務(wù)。

而對(duì)于組網(wǎng)更加迫切、而又沒(méi)有可能架設(shè)**SDH環(huán)路的單位，很多都采用了租用電信運(yùn)營(yíng)商電路的方式。由于SDH基于物理層的特點(diǎn)，單位可在租用電路上承載各種業(yè)務(wù)而不受傳輸?shù)南拗啤３休d方式有很多種，可以是利用基于TDM技術(shù)的綜合復(fù)用設(shè)備實(shí)現(xiàn)多業(yè)務(wù)的復(fù)用，也可以利用基于IP的設(shè)備實(shí)現(xiàn)多業(yè)務(wù)的分組交換。SDH技術(shù)可真正實(shí)現(xiàn)租用電路的帶寬保證，安全性方面也優(yōu)于VPN等方式。在****和對(duì)安全性非常注重的企業(yè)，SDH租用線路得到了***的應(yīng)用。一般來(lái)說(shuō)，SDH可提供E1、E3、STM-1或STM-4等接口，完全可以滿足各種帶寬要求。同時(shí)在價(jià)格方面，也已經(jīng)為大部分單位所接受。主要進(jìn)行光功率放大以延長(zhǎng)光傳輸距離；</p><div
