KCO QSFP+ 40G ER4 40Gb/s QSFP+ SMF 1310 40km Whakawhitiwhiti
HE AHA TE QSFP+ 40G ER4?
+ TeQSFP + 40G ER4 he hototahi 40G QSFP + transceiver kōwae kua rite ki te LC tūhono rua, tae ki te hono ki runga ki te 10km runga OS2 muka aratau kotahi (SMF).
+ Tenei 40G muka whatu transceiver ka haere mai me te rua arai 4 takere QSFP+ tūhono, taea te tapeke o 40 Gbps hōkaiipurangi e ia hongere kawe i te reiti raraunga 10 Gbps.
+ Ka tautokohia te mahi DOM/DDM (mamati diagnostics monitoring) i runga i te 40G fiber optic transceiver ki te whakatutuki i nga waa-a-tuuturu i te aro turuki i nga tawhā whakahaere.
+ I hangaia e matou 40GBASE-ER4 QSFP+ kōwae he rite ki te QSFP + MSA me te IEEE 802.3ba 40GBASE-ER4 whakaritenga. I tua atu, kua whakamatauria te whaa iti ahua-ahua pluggable (QSFP) ER4 optic i runga i nga taputapu kaihautu kia pai ai te hototahi ki nga taputapu Huawei, penei i nga huringa pokapū raraunga, nga pouara hinonga, me nga kaari atanga whatunga tūmau (NIC). Ko te waahanga tuatoru 40G SFP he whakakapi pai ki te Huawei QSFP-40G-ER4 QSFP + 40G transceiver i te utu utu, e whakarato ana i te otinga hototahi utu-utu mo te hononga 40G teitei.
+ QSFP + 40G ER4 optics te whakatutuki i te 40 Gigabit Ethernet (40GbE) hononga muka whatu, he pai mo nga mahi-nui me nga tono tawhiti-roa i roto i nga whatunga-roa, whatunga puni, whatunga metro, etc.

Whakaahuatanga Whanui
Kua hoahoatia te OP-QSFP+-LER ki te whakahaere i runga i te punaha muka aratau kotahi ma te whakamahi i te hongere 4X10 CWDM i te roopu 1310 me te hono ki te 40km. Ka huri te kōwae i te hongere whakauru 4 o te 10Gb/s raraunga hiko ki te 4 CWDM tohu whatu, a multiplexs ratou ki te hongere kotahi mo 40Gb/s tuku whatu. I tua atu, i te taha o te kaiwhiwhi, ka whakakorehia e te kōwae te maha o te whakaurunga 40Gb/s ki roto i nga tohu hongere 4 CWDM, ka huri ki nga raraunga hiko whakaputa 4.
Ko nga roangaru pokapū o nga waahana 4 CWDM ko 1271, 1291, 1311 me 1331 nm. Kei roto he hononga LC matarua mo te atanga whatu me te hono 38-pin mo te atanga hiko. Ka whakamahia te muka aratau-kotahi (SMF) ki tenei kōwae. Ka hurihia e tenei hua nga raraunga whakauru hiko 4-channel 10Gb/s ki roto i nga tohu whatu CWDM (marama), na te raupapa 4-wavelength Distributed Feedback Laser (DFB). Ko nga roangaru e 4 ka whakahiatohia ki te raraunga 40Gb/s kotahi, ka tohatoha mai i te waahanga whakawhiti ma te SMF. Ka whakaaehia e te kōwae kaikawe te whakaurunga tohu tohu 40Gb/s, ka wetewetehia ki roto i nga waahana 4 CWDM 10Gb/s. Ka kohia ia rama roangaru e te diode whakaahua motuhake, ka puta hei raraunga hiko i muri i te whakakaha ake e te TIA.
I hangaia te hua me te ahua ahua, te hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te QSFP + Multi-Source Agreement (MSA) me te whai ki te 40G QSFP + LR4 o IEEE 802.3ba.
