Kuyamba koyamba kwa Optical module
Optical module imapangidwa ndi zida za optoelectronic, mabwalo ogwira ntchito ndi mawonekedwe owoneka bwino. Zida za optoelectronic zili ndi magawo awiri: kutumiza ndi kulandira. Mwachidule, ntchito ya optical module ndiyo kutembenuza chizindikiro cha magetsi kukhala chizindikiro cha kuwala pamapeto otumiza. Pambuyo pa chizindikiro cha kuwala kupyola mu fiber optical, mapeto olandira amasintha chizindikiro cha kuwala mu chizindikiro cha magetsi.
Kufala gawo ndi: athandizira magetsi chizindikiro cha mlingo pang'ono kukonzedwa ndi mkati pagalimoto Chip, ndiyeno amayendetsa semiconductor laser (LD) kapena kuwala emitting diode (LED) kutulutsa modulated kuwala chizindikiro cha mlingo lolingana. The mkati kuwala mphamvu automatic control dera ndi okonzeka kusunga linanena bungwe kuwala chizindikiro mphamvu khola.
Gawo lolandirira ndi: gawo lolowera ma siginecha okhala ndi liwiro linalake limasinthidwa kukhala chizindikiro chamagetsi ndi diode yowunikira, ndipo chizindikiro chamagetsi chokhala ndi liwiro lofananira chimatuluka pambuyo pa preamplifier.
- Lingaliro loyambira la Optical module-
Port-optical module ndi dzina lambiri lamagulu osiyanasiyana a module, nthawi zambiri amatanthauza gawo lophatikizika la transceiver optical.
- Ntchito ya Optical module-
Ntchito yake ndikungozindikira kutembenuka pakati pa zizindikiro za kuwala ndi zizindikiro zamagetsi.
-Optical module kapangidwe-
Ma module opangira mawonekedwe nthawi zambiri amakhala ndi optical transmitter, optical receiver, functional circuit ndi optical (electrical) mawonekedwe.
Pa transmitter, chip cha dalaivala chimayendetsa chizindikiro choyambirira chamagetsi, ndiyeno chimayendetsa semiconductor laser (LD) kapena kuwala emitting diode (LED) kuti ipereke chizindikiro chowoneka bwino.
Doko lili pamapeto olandila. Chizindikiro cha kuwala chikalowa, chimasinthidwa kukhala chizindikiro chamagetsi ndi diode yowunikira, kenako ndimatulutsa chizindikiro chamagetsi kudzera mu preamplifier.
-Optical mode classification-
-Kukula kwa mbiri yakale ya Optical mode-
- Chiyambi cha phukusi la Optical module-
Pali mitundu ingapo yamapaketi a ma module optical, makamaka chifukwa:
》Kuthamanga kwa ukadaulo wa optical fiber communication ndikothamanga kwambiri. Kuthamanga kwa module ya kuwala kukukulirakulira, ndipo voliyumu ikucheperachepera, kotero kuti zaka zingapo zilizonse, zolemba zatsopano zidzaperekedwa.
zolondola Ndizovutanso kukhala ogwirizana pakati pamiyezo yatsopano ndi yakale yolongedza.
》Mawonekedwe a kagwiritsidwe ntchito ka ma optical modules ndi osiyanasiyana. Kutalikirana kosiyanasiyana, zofunikira za bandwidth, ndi malo ogwiritsiridwa ntchito, ofanana ndi mitundu yosiyanasiyana ya fiber optical yomwe imagwiritsidwa ntchito, ma module owoneka amasiyananso.
Chithunzi cha GBIC
GBIC ndi Giga Bitrate Interface Converter.
Isanafike 2000, GBIC inali yodziwika kwambiri yopangira ma module opangira komanso mawonekedwe ogwiritsidwa ntchito kwambiri a gigabit module.
Port SFP
Chifukwa cha kukula kwakukulu kwa GBIC, SFP idawonekera pambuyo pake ndikuyamba kusintha GBIC.
SFP, dzina lathunthu la Small Form-factor Pluggable, ndi gawo laling'ono lotentha lotentha. Kukula kwake kwakung'ono kumagwirizana ndi ma CD a GBIC. Kukula kwa SFP ndi theka laling'ono kuposa la GBIC module, ndipo kuwirikiza kawiri kuchuluka kwa madoko kumatha kukhazikitsidwa pagawo lomwelo. Pankhani ya ntchito, pali kusiyana pang'ono pakati pa ziwirizi, ndipo zonse zimathandizira plugging yotentha. Ma bandwidth apamwamba omwe amathandizidwa ndi SFP ndi 4Gbps
Oral XFP
XFP ndi 10-Gigabit Small Form-factor plugable plugable, yomwe imatha kumveka pang'ono. Ndi 10-Gigabit SFP.
XFP imagwiritsa ntchito moduli yamtundu umodzi yolumikizana ndi XFI (10Gb serial interface), yomwe ingalowe m'malo mwa Xenpak ndi zotumphukira zake.
Port SFP+
SFP +, monga XFP, ndi 10G Optical module.
Kukula kwa SFP + ndi kofanana ndi kwa SFP. Ndiwophatikizika kwambiri kuposa XFP (yochepetsedwa pafupifupi 30%), komanso kugwiritsa ntchito mphamvu zake kumakhala kocheperako (kuchepetsedwa ndi ntchito zina zowongolera).
Chithunzi cha SFP28
SFP yokhala ndi mlingo wa 25Gbps makamaka chifukwa ma modules optical 40G ndi 100G anali okwera mtengo kwambiri panthawiyo, kotero kuti ndondomeko yosinthira kusinthayi inapangidwa.
QSFP/QSFP+/QSFP28/QSFP28-DD
Quad Small Form-factor plugable, mawonekedwe anayi a SFP. Matekinoloje ambiri okhwima mu XFP agwiritsidwa ntchito pamapangidwe awa. QSFP akhoza kugawidwa 4 malinga ndi liwiro × 10G QSFP +, 4 × 25G QSFP28, 8 × 25G QSFP28-DD kuwala gawo, etc.
Tengani QSFP28 mwachitsanzo, yomwe imagwira ntchito pa 4 × 25GE port port. QSFP28 ingagwiritsidwe ntchito kukweza kuchokera ku 25G kupita ku 100G popanda 40G, kuchepetsa kwambiri zovuta za cabling ndi kuchepetsa ndalama.
QSFP/QSFP+/QSFP28/QSFP28-DD
QSFP-DD, yomwe idakhazikitsidwa mu Marichi 2016, imatanthawuza "Double Density". Onjezani mzere wamakanema kumakanema anayi a QSFP ndikusintha kukhala mayendedwe 8.
Itha kukhala yogwirizana ndi dongosolo la QSFP. Gawo loyambirira la QSFP28 litha kugwiritsidwabe ntchito, ingoyikani gawo lina. Chiwerengero cha zala zagolide za OSFP-DD ndizowirikiza kawiri za QSFP28.
QSFP-DD iliyonse imatengera mawonekedwe a 25Gbps NRZ kapena 50Gbps PAM4. Ndi PAM4, imatha kuthandizira mpaka 400Gbps.
OSFP
OSFP, Octal Small Form Factor Pluggable, "O" imayimira "octal", yomwe idakhazikitsidwa mwalamulo mu Novembala 2016.
Zapangidwa kuti zigwiritse ntchito njira zamagetsi za 8 kuti zizindikire 400GbE (8 * 56GbE, koma chizindikiro cha 56GbE chimapangidwa ndi 25G DML laser pansi pa kusintha kwa PAM4), ndipo kukula kwake ndi kwakukulu pang'ono kuposa QSFP-DD. Injini ya kuwala ndi transceiver yokhala ndi madzi okwera kwambiri imakhala ndi ntchito yabwinoko pang'ono yochotsa kutentha.
CFP/CFP2/CFP4/CFP8
Centum gigabits Fomu Yothirika, wandiweyani wavelength division Optical communication module. Mlingo wotumizira ukhoza kufika 100-400Gbpso
CFP idapangidwa pamaziko a mawonekedwe a SFP, okhala ndi kukula kwakukulu ndikuthandizira kutumiza kwa data kwa 100Gbps. CFP ikhoza kuthandizira chizindikiro chimodzi cha 100G ndi chizindikiro chimodzi kapena zingapo za 40G.
Kusiyana pakati pa CFP, CFP2 ndi CFP4 ndi voliyumu. Kuchuluka kwa CFP2 ndi theka la CFP, ndipo CFP4 ndi gawo limodzi mwa magawo anayi alionse a CFP. CFP8 ndi mawonekedwe oyikapo omwe amapangidwira 400G, ndipo kukula kwake ndi kofanana ndi CFP2. Thandizani mitengo ya 25Gbps ndi 50Gbps, ndikuzindikira 400Gbps mlingo wa module kudzera pa 16x25G kapena 8 × 50 mawonekedwe amagetsi.
