40KM 40G QSFP + Optical Transceiver Module
ʻO kaHUAQ40EHe modula transceiver i hoʻolālā ʻia no nā noi kamaʻilio optical 40Km.Hoʻopili ka hoʻolālā i ka 40GBASE-ER4 o ke kūlana IEEE P802.3ba.Hoʻololi ka module i 4 inputs channels (ch) o 10Gb/s ikepili uila i 4 CWDM optical signals, a multiplexs iā lākou i hoʻokahi ala no ka 40Gb/s optical transmission.ʻO ka huli ʻana, ma ka ʻaoʻao hoʻokipa, hoʻopau ka module optically de-multiplexes i kahi hoʻokomo 40Gb/s i nā hōʻailona 4 CWDM, a hoʻohuli iā lākou i 4 channel output ikepili uila.
ʻO nā nalu waena o nā kaha 4 CWDM he 1271, 1291, 1311 a me 1331 nm ma ke ʻano he lālā o ka kaha nalu CWDM i wehewehe ʻia ma ITU-T G694.2.Loaʻa iā ia kahi mea hoʻohui LC duplex no ke kikowaena optical a me kahi mea hoʻohui 38-pin no ke kikowaena uila.No ka hōʻemi ʻana i ka hoʻopuehu ʻana i ka ʻōnaehana lōʻihi, pono e hoʻopili ʻia ka fiber mode hoʻokahi (SMF) i kēia module.
Hoʻolālā ʻia ka huahana me ka form factor, optical/electrical connection and digital diagnostic interface e like me ka QSFP Multi-Source Agreement (MSA).Ua hoʻolālā ʻia e hoʻokō i nā kūlana hana ʻoi loa o waho me ka mahana, ka haʻahaʻa a me ka EMIinterference.
Hoʻohana ka module mai kahi mana + 3.3V hoʻokahi a me nā hōʻailona mana honua LVCMOS/LVTTL e like me Module Present, Reset, Interrupt and Low Power Mode i loaʻa me nā modula.Loaʻa kahi interface serial 2-wire e hoʻouna a loaʻa i nā hōʻailona mana paʻakikī a loaʻa ka ʻike diagnostic diagnostic.Hiki ke hoʻopaʻa ʻia nā kahawai pākahi a hiki ke pani ʻia nā kaha i hoʻohana ʻole ʻia no ka hoʻolālā kiʻekiʻe.
Hoʻololi kēia huahana i ka ʻikepili hoʻokomo uila 4-channel 10Gb/s i nā hōʻailona optical CWDM (māmā), e kahi pūʻulu 4-wavelength Distributed Feedback Laser (DFB).Hoʻohui ʻia ke kukui e nā ʻāpana MUX ma ke ʻano he 40Gb/s data, e hoʻolaha ana i waho o ka module transmitter mai ka SMF.ʻAe ka module receiver i ka hoʻokomo ʻana i nā hōʻailona optical 40Gb/s CWDM, a hoʻokaʻawale iā ia i loko o 4 mau kaha 10Gb/s me nā hawewe like ʻole.ʻOhi ʻia kēlā me kēia kukui lōʻihi hawewe e kahi discrete avalanche photodiode (APD), a laila hoʻopuka ʻia ma ke ʻano he ʻikepili uila ma hope o ka hoʻonui ʻia ʻana e kahi TIA a laila e ka pou amplifier.
ʻO kaHUAQ40Eua hoʻolālā ʻia me ka form factor, optical/electrical connection and digital diagnostic interface e like me ka QSFP Multi-Source Agreement (MSA).Ua hoʻolālā ʻia e hālāwai me nā kūlana hana ʻoi loa o waho e pili ana i ka mahana, ka haʻahaʻa a me ka hoʻopili EMI.Hāʻawi ka module i ka hana kiʻekiʻe loa a me ka hoʻohui ʻana i nā hiʻohiʻona, hiki ke loaʻa ma o kahi interface serial ʻelua-wire.
