CFP/CFP2/CFP4 Optical Module

CFP MSA ndiyo njira yoyamba yamakampani yothandizira 40 ndi 100Gbe Ethernet optical transceivers.CFP multi-source protocol ndiyo kufotokozera ndondomeko yopangira ma modules otentha otentha kuti apititse patsogolo ntchito za 40 ndi 100Gbit / s, kuphatikizapo mapulogalamu a Ethernet othamanga kwambiri (40 ndi 100GbE).Mitundu ya phukusi la 100G CFP series optical modules ndi CFP, CFP2, ndi CFP4.

Kuyamba kwa CFP/CFP2/CFP4 Optical Module

Kukula kwa CFP Optical module ndi yayikulu kwambiri, CFP2 optical module ndi theka la CFP, CFP4 optical module ndi gawo limodzi mwa magawo anayi a CFP, ndipo mawonekedwe a phukusi la QSFP28 optical module ndi laling'ono kuposa la CFP4 gawo la kuwala.Kuchuluka kwa ma modules atatuwa, monga momwe tawonetsera pansipa.Chomwe chiyenera kukumbutsidwa ndi chakuti CFP / CFP2 / CFP4 optical modules sangathe kugwiritsidwa ntchito mosiyana, koma angagwiritsidwe ntchito panthawi imodzi mu dongosolo lomwelo.

Ma CFP optical modules amathandizira kufalitsa pamtundu umodzi ndi ma multi-mode optical fibers omwe ali ndi maulendo angapo, ma protocol, ndi utali wolumikizira monga momwe akufunira, kuphatikizapo mawonekedwe onse okhudzana ndi thupi (PMD) omwe akuphatikizidwa mu IEEE802.3ba standard.

CFP optical module imapangidwa pamaziko a mawonekedwe ang'onoang'ono a pluggable optical module (SFP), ndi kukula kwakukulu ndikuthandizira kutumiza deta ya 100 Gbps.CFP optical module ikhoza kuthandizira chizindikiro chimodzi cha 100G, OTU4, chizindikiro chimodzi kapena zingapo za 40G, OTU3 kapena STM-256 / OC-768.

100G CFP2 nthawi zambiri imagwiritsidwa ntchito ngati cholumikizira cha 100G Ethernet cholumikizira, chokhala ndi kuthekera kopitilira muyeso kuposa ma CFP optical modules, ndipo kukula kwake kocheperako kumapangitsa kukhala koyenera kwa waya wapamwamba kwambiri.

The 100G CFP4 optical module ili ndi liwiro lofanana ndi CFP / CFP2 optical module.Kuchita bwino kwapatsirana kumakhala bwino kwambiri, koma kugwiritsa ntchito mphamvu kumachepetsedwa, ndipo mtengo wake ndi wotsika kuposa CFP2.Choncho, CFP4 Optical module ili ndi ubwino wosasinthika.Lankhulani za ubwino wa CFP4 Optical modules.

Ubwino wa CFP4 Optical module

1. Kupititsa patsogolo kupititsa patsogolo: Mawonekedwe oyambirira a 100G CFP optical module adapeza njira yotumizira 100G kupyolera muzitsulo za 10 10G, pamene 100G CFP4 optical module yamakono ikukwaniritsa kufalikira kwa 100G kudzera muzitsulo za 4 25G, kotero kuti kupititsa patsogolo kumakhala kwakukulu.Kukhazikika kumakhala kolimba.

2. Voliyumu yaying'ono: Voliyumu ya CFP4 optical module ndi gawo limodzi mwachinayi la CFP, lomwe ndilo gawo laling'ono kwambiri la optical mu CFP series of optical modules.

3. Kuphatikizika kwa gawo lapamwamba: Kuphatikizika kwa CFP2 kumawirikiza kawiri kuposa CFP, ndipo mlingo wa mgwirizano wa CFP4 ndi kanayi wa CFP.

4. Kugwiritsa ntchito mphamvu zochepa komanso mtengo wake: Kupititsa patsogolo kwa CFP4 optical modules kumakhala bwino kwambiri, koma kugwiritsira ntchito mphamvu kumachepetsedwa, ndipo mtengo wa dongosolo umakhalanso wotsika kuposa CFP2.

Powombetsa mkota

Mbadwo woyamba wa 100G optical module unali waukulu kwambiri wa CFP optical module, ndiyeno CFP2 ndi CFP4 optical modules anawonekera.Pakati pawo, CFP4 optical module ndi mbadwo watsopano wa 100G optical modules, ndipo m'lifupi mwake ndi 1/4 yokha ya CFP optical module.Mapangidwe a phukusi la QSFP28 optical module ndi laling'ono kusiyana ndi la CFP4 optical module, zomwe zikutanthauza kuti QSFP28 optical module ili ndi mawonekedwe apamwamba a doko pakusintha.

Ngakhale kuti QSFP28 optical module ili ndi ubwino wambiri, ndi imodzi mwa njira zothetsera maukonde a 100G.Kwa mapulogalamu apadera monga malo opangira deta ndi zipinda zosinthira, kusankha koyenera ndiye njira yabwino kwambiri.

HUANET imapereka mitundu yonse ya 100G CFP/CFP2/CFP4 ndi 100G QSFP28 yokhala ndi mawonekedwe apamwamba komanso ogwirizana bwino pamtengo wotsika kwambiri.
