Modula Transceiver Optical 10KM 40G QSFP+
ʻO kaQSFP+ Ua hoʻolālā ʻia nā modula transceiver no ka hoʻohana ʻana i nā loulou 40 Gigabit i kekona ma luna o ka fiber multimode. Ua kūlike lākou me ka QSFP+ MSA a me IEEE 802.3ba 40GBASE-SR4. Hoʻokomo ka ʻāpana transmiter optical o ka transceiver i kahi pūʻulu VCSEL (Vertical Cavity Surface Emitting Laser) 4-channel, kahi buffer input 4-channel a me ka mea hoʻokele laser, nā poloka kaohi a me nā bias. Hoʻokomo ka ʻāpana mea hoʻokipa optical o ka transceiver i kahi pūʻulu photodiode PIN 4-channel, kahi pūʻulu TIA 4-channel, kahi buffer output 4 channel, nā poloka kaohi.

Modula Hoʻololi Optical 40KM 40G QSFP+
ʻO kaHUAQ40EHe modula transceiver i hoʻolālā ʻia no nā noi kamaʻilio optical 40Km. Kūlike ka hoʻolālā me 40GBASE-ER4 o ke kūlana IEEE P802.3ba. Hoʻololi ka modula i nā kahawai hoʻokomo 4 (ch) o ka ʻikepili uila 10Gb/s i nā hōʻailona optical 4 CWDM, a hoʻonui iā lākou i loko o hoʻokahi kahawai no ka hoʻoili optical 40Gb/s. Ma ke ʻano ʻē aʻe, ma ka ʻaoʻao loaʻa, hoʻokaʻawale ka modula i nā multiplex optical i kahi hoʻokomo 40Gb/s i loko o nā hōʻailona kahawai 4 CWDM, a hoʻololi iā lākou i ka ʻikepili uila hoʻopuka 4 kahawai.
ʻO nā nalu waena o nā kahawai 4 CWDM he 1271, 1291, 1311 a me 1331 nm ma ke ʻano he mau lālā o ka grid nalu CWDM i wehewehe ʻia ma ITU-T G694.2. Loaʻa iā ia kahi mea hoʻohui LC duplex no ka interface optical a me kahi mea hoʻohui 38-pin no ka interface uila. No ka hōʻemi ʻana i ka hoʻopuehu optical i ka ʻōnaehana lōʻihi, pono e hoʻopili ʻia ka fiber mode hoʻokahi (SMF) i loko o kēia module.
Ua hoʻolālā ʻia ka huahana me ke ʻano kumu, ka pilina optical/uila a me ka pilina diagnostic kikohoʻe e like me ka QSFP Multi-Source Agreement (MSA). Ua hoʻolālā ʻia e hoʻokō i nā kūlana hana waho ʻoi loa e like me ka mahana, ka haʻahaʻa a me ka pilikia EMI.
Hana ka module mai kahi lako mana hoʻokahi +3.3V a loaʻa nā hōʻailona mana honua LVCMOS/LVTTL e like me Module Present, Reset, Interrupt a me Low Power Mode me nā modules. Loaʻa kahi interface serial 2-wire e hoʻouna a loaʻa i nā hōʻailona mana paʻakikī a e loaʻa ka ʻike diagnostic kikohoʻe. Hiki ke hoʻoponopono ʻia nā kahawai pākahi a hiki ke pani ʻia nā kahawai i hoʻohana ʻole ʻia no ka maʻalahi o ka hoʻolālā.
Hoʻololi kēia huahana i ka ʻikepili hoʻokomo uila 4-channel 10Gb/s i nā hōʻailona optical CWDM (kukui), e kahi pūʻulu 4-wavelength Distributed Feedback Laser (DFB) i hoʻokele ʻia. Hoʻohui ʻia ke kukui e nā ʻāpana MUX ma ke ʻano he ʻikepili 40Gb/s, e hoʻolaha ana mai ka module transmitter mai ka SMF. ʻAe ka module receiver i ka hoʻokomo hōʻailona optical CWDM 40Gb/s, a hoʻokaʻawale iā ia i loko o 4 mau kahawai 10Gb/s pākahi me nā nalu like ʻole. Hoʻiliʻili ʻia kēlā me kēia kukui nalu e kahi photodiode avalanche discrete (APD), a laila hoʻopuka ʻia ma ke ʻano he ʻikepili uila ma hope o ka hoʻonui mua ʻia e kahi TIA a laila e kahi amplifier post.
ʻO kaHUAQ40EUa hoʻolālā ʻia me ke ʻano kumu, ka pilina optical/uila a me ka pilina diagnostic kikohoʻe e like me ka QSFP Multi-Source Agreement (MSA). Ua hoʻolālā ʻia e hoʻokō i nā kūlana hana waho ʻoi loa e like me ka mahana, ka haʻahaʻa a me ka hoʻopilikia EMI. Hāʻawi ka module i ka hana kiʻekiʻe loa a me ka hoʻohui ʻana i nā hiʻohiʻona, hiki ke komo ma o kahi interface serial ʻelua-wire.
