VH4000(或'' VHub '' )AURORA公司充分利用了幾項(xiàng)新技術(shù)大大改變了多系統(tǒng)運(yùn)營商部署樞紐設(shè)施在他們的網(wǎng)絡(luò),節(jié)省了大部分資本支出,并且推出了先進(jìn)的服務(wù)。 Comprised of field hardened dense wave division multiplexing (DWDM) optical passives, node-installed EDFAs, optical switches, and other special-purpose modules, the VHub allows MSOs to configure hub sites within a compact strand- or pedestal-mounted housing.包括無源光網(wǎng)絡(luò)的DWDM技術(shù),可在V-Hub里安裝的摻鉺光纖放大器,光開關(guān),以及其他特殊用途的模塊。V-Hub可以讓多業(yè)務(wù)運(yùn)營商將系統(tǒng)設(shè)置在緊湊型機(jī)房或野外式基座上。 A single VHub can feed 16 to 24 unique optical signals to areas of 10,000 to 20,000 households, and requires no external cooling or ventilation.單一VHub可以覆蓋光信號(hào)領(lǐng)域的10000至20000戶,并無需外部冷卻或通風(fēng)。 With this platform, MSOs can quickly and easily deliver services such as VoD, VoIP, high speed data and network DVR, without the need to acquire property, construct controlled facilities or deploy distributed servers and switching devices.通過這一平臺(tái),多系統(tǒng)運(yùn)營商可以快速,便捷地提供服務(wù),如視頻點(diǎn)播,網(wǎng)絡(luò)電話,高速數(shù)據(jù)和網(wǎng)絡(luò)DVR ,而不需要獲得多余的付出,控制設(shè)施建設(shè)或部署分布式服務(wù)器和交換設(shè)備。 A single master facility can feed a large number of VHubs in surrounding communities, providing significant cost savings.一個(gè)主設(shè)備可以提供給大量周邊社區(qū)服務(wù),提供了大量的成本節(jié)約。 The Aurora NC4000 series Optical Node Chassis provides a rugged and environmentally stable enclosure for the optical components of the VHub.V-Hub設(shè)計(jì)緊湊,可支持多路RF 輸出和多個(gè)可擴(kuò)展光模塊的靈活設(shè)計(jì),還包括對(duì)數(shù)字化回傳技術(shù)和DWDM 支持,節(jié)點(diǎn)的狀態(tài)監(jiān)控集成于數(shù)字回傳系統(tǒng),消除了額外的監(jiān)控信息收發(fā)器件的需求。V-Hub可支持傳統(tǒng)的HFC 接入,光纖以太網(wǎng)接入和無線(Wi-Fi 802.11a,b,g)的接入,這種真正的多接入只需通過簡(jiǎn)單的模塊替換而得以實(shí)現(xiàn)??勺尠惭b多達(dá)12個(gè)不同的光網(wǎng)絡(luò)模塊和單或雙冗余電源。
