Kuyenda Mwapang'onopang'ono kwa Cable kupita ku Fiber

Kodi makampani opanga ma cable adzayenda mwachangu bwanji kupita kumalo opangira ulusi wonse?Katswiri wa zachuma wa Credit Suisse akukhulupirira kuti makampaniwa adzachedwa kukweza kuchokera ku coax m'madera ochepa omwe alibe mpikisano, osawona kufulumira kwa kupititsa patsogolo kwa teknoloji yofulumira, yodalirika, yofulumira komanso yowonjezereka yomwe imayendetsedwa ndi mpikisano mkati mwa misika yomwe amatumikira.

"Tikuyembekeza kuti zisankho zamitundumitundu zipangidwe m'malo osiyanasiyana [anthu ochuluka]," atero a Grant Joslin, Wachiwiri kwa Purezidenti US Telecom Equity Research, Credit Suisse."Ngati muli kudera lomwe muli ndi ma millimeter wave opanda zingwe ndipo muli ndi mpikisano wa fiber m'modzi kapena awiri kapena atatu opikisana nawo ulusi, ndiye mtundu wamalo omwe mungayambire [kukweza kwa DOCSIS] poyamba ndipo mukangomva kumene. 'Ndili ndi zigawo zomwe zikubwera, mungakonde kuchita izi. "

Joslin adati sipakhala mwachangu kukweza ku DOCSIS 4.0 m'misika yomwe ili ndi mpikisano wocheperako.Madera akumidzi omwe alibe mpikisano wa fiber amasinthidwa kukhala maziko odzitchinjiriza, pomwe madera akumidzi ndi akumidzi akuyembekezeredwa kukhala omaliza kukwezedwa.Ananenanso kuti kukweza kuchokera ku DOCSIS 3.1 kupita ku 4.0 kuyenera kukhala kwapang'onopang'ono ndipo sikungabweretse ndalama zambiri kwa ogwira ntchito akuluakulu, malinga ndi ndalama zomwe zilipo kale.

"Charter ndi Comcast amawononga $ 9 mpaka $ 10 biliyoni pachaka pantchito yawo monga mwanthawi zonse CapEx," adatero Joslin."Tikuganiza kuti mtengo wonse wa kukweza kwa [DOCSIS 4.0] pazaka zambiri zomwe zichitike zili penapake pa $10 mpaka $11 biliyoni."

Njira yopititsira patsogolo ya DOCSIS 4.0 imapereka ndalama zotsika mtengo kwa ogwiritsa ntchito ma chingwe kuwonjezera pa liwiro la ogwiritsa ntchito la 9 Gbps kutsika ndi 4 Mbps kumtunda, kuphatikiza kudalirika mwakuyang'anira zida zam'munda ndikuchepetsa kufunikira kwa kugawanika kwa node kogwiritsa ntchito kwambiri powonjezera zina. mphamvu zonse mu coax mbali ya netiweki.

Joslin adanenanso kuti ogwiritsa ntchito zingwe ambiri sapeza kudalirika kwa fiber kudzera pakukweza kwa DOCSIS 4.0, koma makampaniwa akumanga mwakachetechete njira yopita ku fiber zonse kudzera muzotulutsa zawo zaposachedwa."Monga gawo la Gawo 1 lakusintha pali ukadaulo wotchedwa GAP, nsanja yofikira anthu onse.Ngati wogwiritsa ntchito awona kuti palibenso ntchito yotaya ndalama zabwino pambuyo poipa kapena sakuwonanso moyo waukadaulo wa DOCSIS, ndikusinthana kwa module [kuti mupite ku fiber].

Othandizira amatha kusuntha kupita ku fiber pang'onopang'ono, poyamba kusamutsa ogwiritsa ntchito ma bandwidth apamwamba pa fiber kuti athetse kupanikizika pa coax network ndiyeno potsirizira pake amakweza aliyense kukhala fiber."Ndi njira yabwino kwambiri [yosamuka] kuposa kuwotcha maukonde onse ndikuyika ina," adatero Joslin.
