1RU QAM Analyzer yokhala ndi Mtambo, Mphamvu ndi MER ya DVB-C ndi DOCSIS, MKQ124

Kufotokozera Kwachidule:

MKQ124 ndi QAM Analyzer yamphamvu komanso yosavuta kugwiritsa ntchito yomwe cholinga chake ndi kuyang'anira ndikupereka lipoti la thanzi la Digital Cable ndi netiweki ya HFC.

Imatha kulemba nthawi zonse miyezo yonse mu mafayilo a malipoti ndikutumizaSNMPmisampha munthawi yeniyeni ngati mitengo ya magawo osankhidwa ikupitirira malire ofotokozedwa. Pothetsa mavuto aWEB GUIimalola mwayi wofikira kutali/kwanuko ku magawo onse owunikira pa gawo la RF lenileni ndi zigawo za DVB-C / DOCSIS.

MKQ124 ndi QAM Analyzer yamphamvu komanso yosavuta kugwiritsa ntchito yomwe cholinga chake ndi kuyang'anira ndikupereka lipoti la thanzi la Digital Cable ndi netiweki ya HFC.

Imatha kulemba nthawi zonse miyezo yonse m'mafayilo a malipoti ndikutumiza SNMP traps nthawi yeniyeni ngati miyezo yosankhidwa ya magawo imadutsa malire ofotokozedwa. Pothetsa mavuto, WEB GUI imalola mwayi wofikira patali / wakomweko ku magawo onse owunikira pa RF layer yeniyeni ndi zigawo za DVB-C / DOCSIS.

MKQ124 ndi QAM Analyzer yamphamvu komanso yosavuta kugwiritsa ntchito yomwe cholinga chake ndi kuyang'anira ndikupereka lipoti la thanzi la Digital Cable ndi netiweki ya HFC.

Pamene chiwerengero cha olembetsa a Digital Cable TV ndi DOCSIS chikuchulukirachulukira padziko lonse lapansi ndipo Ubwino wa Utumiki wakhala chinthu chofunikira kwambiri pochepetsa kuchuluka kwa olembetsa, MKQ124 ndi chida chabwino kwambiri chowunikira bwino khalidwe loperekedwa maola 24 pa tsiku, masiku 7 pa sabata, masiku 7 pa sabata. Wogwiritsa ntchito chingwe akhoza kuchiyika pamalo olowera/kumalo olumikizirana, pamtunda womaliza, kapena pamalo olembetsera.

MKQ124 ndi njira yaying'ono yoyendetsera ma frequency/amplitude/constellation/BER responses pa njira zonse za QAM. Pogwiritsa ntchito magawo owunikira awa, wogwiritsa ntchito akhoza kukhala wodzipereka kukonza vuto la mtundu wa chingwe komanso kupeza malo omwe kuwonongeka kukukhudza ntchito.

Ubwino

➢ Kuyang'anira thanzi la netiweki yanu ya CATV patali komanso m'deralo

➢ Kuwunika QAM nthawi yeniyeni komanso mosalekeza

➢ Kulondola Kwambiri kwa mphamvu ndi kupendekera kwakutali: +/-1dB ya Mphamvu, +/-1.5dB ya MER

➢ Kutsimikizira njira yopita patsogolo ya HFC ndi mtundu wa RF yotumizira

➢ Chowunikira cha Spectrum Chophatikizidwa kuyambira 5 MHz mpaka 1 GHz

Makhalidwe

➢ Thandizo lathunthu la DVB-C ndi DOCSIS

➢ Thandizo la ITU-J83 Annexes A, B, ndi C

➢ Chizindikiro cha chenjezo cha ogwiritsa ntchito ndi malire ake, thandizirani mbiri ziwiri za njira: pulani A / pulani B

➢ Madoko a 2x RF mkati, 4x RJ45 (2x WAN + 2x LAN) mu 1 RU

➢ Muyeso wolondola wa magawo ofunikira a RF

➢ Thandizo la TCP / UCP / DHCP / HTTP / SNMP

➢ Chipinda chodziyimira pachokha

Magawo Owunikira

➢ 64 QAM / 256 QAM / 4096 QAM (Chosankha) / OFDM (Chosankha)

➢ Mphamvu ya RF: -15 mpaka + 50 dBmV

➢ MER: 20 mpaka 50 dB

➢ Kuwerengera koyenera kwa Pre-BER ndi RS

➢ Kuwerengera kosalondola kwa Post-BER ndi RS

➢ Gulu la nyenyezi

Mapulogalamu

➢ Kuwunika kwa netiweki ya DVB-C ndi DOCSIS Digital Cable

➢ Kuwunika njira zambiri

➢ Kusanthula kwa QAM kwa nthawi yeniyeni
