KCO QSFP+ 40G ER4 40Gb/s QSFP+ SMF 1310 40km Whakawhitiwhiti
He aha te QSFP+ 40G ER4?
+ TeHe hototahi te QSFP+ 40G ER4. Kua rite te waeine whakawhiti QSFP+ 40G ki ngā hononga LC takirua, e taea ai te hono atu ki te 10km mā te muka aratau-kotahi OS2 (SMF).
+ Kei tēnei taputapu whakawhiti muka whatu 40G he hononga QSFP+ e rua ngā huarahi, e 4 ngā hongere, e āhei ai te tapeke o te whānui o te 40 Gbps mō ia hongere me te tere raraunga 10 Gbps.
+ E tautokona ana te mahi DOM/DDM (aroturukitanga tātaritanga mamati) i runga i te taputapu whakawhiti muka whatu 40G hei whakatutuki i te aroturukitanga o ngā tawhā whakahaere wā-tūturu.
+ I hangaia e mātou te kōwae 40GBASE-ER4 QSFP+ e tutuki ana i ngā whakaritenga QSFP+ MSA me te IEEE 802.3ba 40GBASE-ER4. Haunga tēnā, kua whakamatautauria te whatu mono-āhua iti whā (QSFP) ER4 i runga i ngā taputapu manaaki hei whakarite i te hototahitanga katoa ki ngā taputapu Huawei, pērā i ngā pana pokapū raraunga, ngā pouara hinonga, me ngā kāri atanga whatunga tūmau (NIC). He whakakapinga pai te kōwae 40G SFP tuatoru mō te taputapu whakawhiti Huawei QSFP-40G-ER4 QSFP+ 40G i te utu whaitake, e whakarato ana i tētahi otinga hototahi utu-pai mō te hononga 40G mahi-teitei.
+ Ka taea e ngā whatu QSFP+ 40G ER4 te whakatutuki i ngā hononga muka whatu 40 Gigabit Ethernet (40GbE), he mea tino pai mō ngā tono mahi-teitei me ngā tono tawhiti-roa i roto i ngā whatunga tawhiti-roa, ngā whatunga puni, ngā whatunga metro, me ētahi atu.

Whakaahuatanga Whānui
Kua hangaia te OP-QSFP+-LER kia whakahaerehia i runga i te pūnaha muka aratau-kotahi mā te whakamahi i te hongere 4X10 CWDM i roto i te roopu 1310, ā, ka hono atu ki te 40km. Ka hurihia e te kōwae ngā hongere whakauru e 4 o ngā raraunga hiko 10Gb/s ki ngā tohu whatu CWDM e 4, ā, ka whakareatia kia kotahi te hongere mō te tuku whatu 40Gb/s. I te taha whakamuri, i te taha kaiwhiwhi, ka wetewetehia e te kōwae te whakaurunga 40Gb/s ki ngā tohu hongere CWDM e 4, ā, ka hurihia hei raraunga hiko putanga hongere e 4.
Ko ngā roangaru matua o ngā hongere CWDM e 4 ko 1271, 1291, 1311 me te 1331 nm. Kei roto he hononga LC takirua mō te atanga whatu me te hononga 38-pine mō te atanga hiko. Ka whakamahia te muka aratau-kotahi (SMF) i roto i tēnei kōwae. Ka hurihia e tēnei hua ngā raraunga whakauru hiko 10Gb/s 4-hongere ki ngā tohu whatu CWDM (mārama), mā te huinga Taiaho Urupare Tohatoha 4-roangaru (DFB). Ka whakareatia ngā roangaru e 4 ki roto i te raraunga 40Gb/s kotahi, ka horapa atu i te kōwae tuku mā te SMF. Ka tangohia e te kōwae kaiwhiwhi te whakaurunga tohu whatu 40Gb/s, ā, ka wetewetehia ki roto i ngā hongere 10Gb/s 4 CWDM. Ka kohia ia mārama roangaru e tētahi diode whakaahua motuhake, kātahi ka tukuna hei raraunga hiko i muri i te whakanui ake e te TIA.
Kua hoahoatia te hua me te atanga āhua, hononga whatu/hiko me te atanga tātaritanga mamati e ai ki te Whakaaetanga Pūtake Maha QSFP+ (MSA) ā, e tutuki ana hoki i te 40G QSFP+ LR4 o IEEE 802.3ba.
