CFP/CFP2/CFP4 Optical Module

CFP MSA ndiye muyezo woyamba wamakampani wothandizira ma transceivers a 40 ndi 100Gbe Ethernet. Njira ya CFP multi-source ndiyo kufotokoza njira yopangira ma modules optical osinthika kuti alimbikitse mapulogalamu a 40 ndi 100Gbit/s, kuphatikiza mapulogalamu a Ethernet othamanga kwambiri a m'badwo wotsatira (40 ndi 100GbE). Mitundu ya ma phukusi a ma modules optical a 100G CFP series ndi CFP, CFP2, ndi CFP4.

Chiyambi cha CFP/CFP2/CFP4 Optical Module

Kukula kwa CFP optical module ndiko kwakukulu, CFP2 optical module ndi theka la CFP, CFP4 optical module ndi gawo limodzi mwa magawo anayi a CFP, ndipo kalembedwe ka phukusi la QSFP28 optical module ndi kakang'ono kuposa ka CFP4 optical module. Kuchuluka kwa ma module atatuwa, Monga momwe tawonetsera pansipa. Chomwe chiyenera kukumbukiridwa ndichakuti ma module optical a CFP/CFP2/CFP4 sangagwiritsidwe ntchito mosinthana, koma angagwiritsidwe ntchito nthawi imodzi mu dongosolo lomwelo.

Ma module a CFP optical amathandizira kutumiza mauthenga pa single-mode ndi multi-mode optical fibers okhala ndi liwiro losiyanasiyana, ma protocol, ndi kutalika kwa ma link monga momwe amafunikira, kuphatikiza ma physical medium-related interfaces onse omwe ali mu IEEE802.3ba standard.

CFP optical module idapangidwa pogwiritsa ntchito mawonekedwe ang'onoang'ono otseguka a optical module (SFP), okhala ndi kukula kwakukulu komanso othandizira kutumiza deta ya 100 Gbps. CFP optical module imatha 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 cholumikizira cha 100G Ethernet, chokhala ndi mphamvu yotumizira ma transmissions apamwamba kuposa ma CFP optical modules, ndipo kukula kwake kochepa kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito mawaya ambiri.

Module ya 100G CFP4 optical ili ndi liwiro lofanana ndi module ya CFP/CFP2 optical. Mphamvu yotumizira imawonjezeka kwambiri, koma kugwiritsa ntchito mphamvu kumachepa, ndipo mtengo wake ndi wotsika kuposa CFP2. Chifukwa chake, module ya CFP4 optical ili ndi zabwino zosasinthika. Kambiranani za zabwino za ma module a CFP4 optical.

Ubwino wa CFP4 optical module

1. Kugwira bwino ntchito kwa ma transmission: Module yoyambirira ya 100G CFP optical inapeza kuchuluka kwa ma transmission a 100G mpaka 10G, pomwe module ya 100G CFP4 yomwe ilipo pano imapeza ma transmission a 100G kudzera m'ma channel anayi a 25G, kotero kuti ma transmission amayenda bwino kwambiri. Kukhazikika kumakhala kolimba.

2. Voliyumu yaying'ono: Voliyumu ya CFP4 optical module ndi gawo limodzi mwa magawo anayi a CFP, yomwe ndi module yaying'ono kwambiri ya optical mu mndandanda wa CFP wa ma optical module.

3. Kuphatikiza kwa ma module apamwamba: Mlingo wophatikiza wa CFP2 ndi kawiri kuposa wa CFP, ndipo mlingo wophatikiza wa CFP4 ndi kanayi kuposa wa CFP.

4. Kugwiritsa ntchito mphamvu zochepa komanso mtengo wotsika: Kugwiritsa ntchito bwino kwa ma module a CFP4 optical kwakula kwambiri, koma kugwiritsa ntchito mphamvu kwachepa, ndipo mtengo wa makinawo ndi wotsika kuposa wa CFP2.

Powombetsa mkota

Module ya optical ya m'badwo woyamba ya 100G inali module yayikulu kwambiri ya CFP optical, kenako ma module a CFP2 ndi CFP4 optical adawonekera. Pakati pawo, module ya optical ya CFP4 ndi m'badwo waposachedwa wa ma module a 100G optical, ndipo m'lifupi mwake ndi 1/4 yokha ya module ya optical ya CFP. Kalembedwe ka ma CD a module ya optical ya QSFP28 ndi kakang'ono kuposa ka module ya optical ya CFP4, zomwe zikutanthauza kuti module ya optical ya QSFP28 ili ndi kuchuluka kwa ma port pa switch.

Ngakhale kuti QSFP28 optical module ili ndi zabwino zambiri, ndi imodzi mwa njira zambiri zothetsera ma network a 100G. Pa mapulogalamu enaake monga malo osungira deta ndi zipinda zosinthira, kusankha yoyenera ndiye yankho labwino kwambiri.

HUANET imapereka mitundu yonse ya 100G CFP/CFP2/CFP4 ndi 100G QSFP28 yokhala ndi khalidwe lapamwamba komanso yogwirizana bwino pamtengo wotsika kwambiri.
