Liwiro la optical module SFP + ndi: 10G SFP + optical transceiver ndikukweza kwa SFP (nthawi zina amatchedwa "mini-GBIC"). SFP yakhala ikugwiritsidwa ntchito kwambiri pa Gigabit Ethernet ndi 1G, 2G, ndi 4G Fiber Channel. Kuti zigwirizane ndi kuchuluka kwa data, SFP + yapanga zotchingira ma elekitirodi otetezedwa ndi mawonekedwe owongolera mazizindikiro kuposa SFP, ndipo yapanga mawonekedwe atsopano amagetsi.
Mlozera wa mawonekedwe a SFP Optical module
1. Mphamvu yamagetsi yotulutsa mphamvu yotulutsa mphamvu imatanthawuza mphamvu yotulutsa kuwala kwa gwero la kuwala pamapeto otumiza optical module, unit: dBm.
2. Analandira mphamvu ya kuwala Analandira mphamvu ya kuwala imatanthawuza mphamvu ya kuwala yomwe inalandira pamapeto a optical module, unit: dBm.
3. Landirani kukhudzika Landirani kukhudzika kumatanthauza mphamvu yochepera yolandirira ya module ya Optical pamlingo wina ndi kulakwitsa pang'ono, mu dBm. Muzochitika zodziwika bwino, kuwonjezereka kwa mlingo, kuwonjezereka kwa mphamvu zolandirira, ndiko kuti, mphamvu yocheperapo yolandirira yolandira kuwala, ndipamwamba zofunikira pa chipangizo cholandira cha module optical.
4. Saturated Optical power, yomwe imadziwikanso kuti Optical saturation, imatanthawuza kuchulukitsitsa kwamphamvu kwamphamvu pamene pali zolakwika zina (10-10).～10-12) imasungidwa pamlingo wina wotumizira.
Tikumbukenso kuti photodetector adzakhutitsa photocurrent pansi kuwala kwamphamvu. Izi zikachitika, chojambuliracho chimafunika nthawi kuti chibwezeretse. Panthawiyi, kukhudzidwa kwa kulandira kumachepa ndipo chizindikiro cholandiridwa chikhoza kuganiziridwa molakwika. Zimayambitsa zolakwika pang'ono, ndipo ndizosavuta kuwononga chowunikira cholandirira. Pogwiritsidwa ntchito, iyenera kuyesetsa kupewa kupitilira mphamvu zake zowoneka bwino.
Zindikirani kuti kwa ma module otalikirapo optical, popeza mphamvu yamagetsi yotulutsa nthawi zambiri imakhala yayikulu kuposa mphamvu zake zodzaza, chonde samalani kutalika kwa fiber mukamagwiritsa ntchito kuti muwonetsetse kuti mphamvu yolandila yolandila ifika pagawo la kuwala. ndi ocheperapo kuposa mphamvu zake zowoneka bwino. Optical module yawonongeka.
Zigawo za SFP Optical modules
The zikuchokera SFP kuwala gawo ndi: laser: kuphatikizapo transmitter TOSA ndi wolandila ROSA dera bolodi IC, ndi Chalk kunja ndi: chipolopolo, maziko, PCBA, kukoka mphete, lamba, potsekula chidutswa, pulagi labala. Kuphatikiza apo, kuti muzindikire mosavuta, Nthawi zambiri, mtundu wa gawo la gawoli umadziwika ndi mtundu wa mphete yokoka. Mwachitsanzo: mphete yokoka yakuda imakhala yamitundu yambiri, kutalika kwake ndi 850nm; buluu ndiye gawo lokhala ndi kutalika kwa 1310nm; wachikasu ndi gawo lokhala ndi kutalika kwa 1550nm; wofiirira ndiye gawo lokhala ndi kutalika kwa 1490nm.
SFP, SFF ndi GBIC optical module ubale
SFP ndiye chidule cha Small Form-factor plugables, ndiko kuti, gawo laling'ono lotha pluggable Optical module. SFP ikhoza kuwonedwa ngati mtundu wosinthika wa SFF. Mawonekedwe ake amagetsi ndi chala chagolide cha pini 20. Mawonekedwe azizindikiro za data ali ofanana ndi gawo la SFF. Gawo la SFP limaperekanso mawonekedwe owongolera a I2C, ogwirizana ndi SFP-8472 standard optical interface diagnostics. Onse SFF ndi SFP samaphatikizapo gawo la SerDes, ndipo amangopereka mawonekedwe amtundu wa data. Malipiro a CDR ndi magetsi obalalitsidwa amaikidwa kunja kwa gawoli, kupanga kukula kochepa komanso kutsika kwa mphamvu zogwiritsira ntchito mphamvu. Chifukwa cha kuchepa kwa kutentha kwa kutentha, SFF/SFP ingagwiritsidwe ntchito pa mtunda waufupi kwambiri, mtunda waufupi komanso wapakati pa 2.5Gbps ndi pansi.
SFP Optical modules tsopano ali ndi liwiro lalikulu la 10G, ndipo ambiri amagwiritsa ntchito LC interfaces. Itha kumveka ngati mtundu wokwezedwa wa GBIC. Kuchuluka kwa ma module a SFP optical kumachepetsedwa ndi theka poyerekeza ndi GBIC optical modules, ndipo kupitirira kawiri chiwerengero cha madoko chikhoza kukhazikitsidwa pagawo lomwelo. Pankhani ya ntchito zina, zoyambira za SFP module ndizofanana ndi GBIC. Choncho, enakusinthaopanga amatcha SFP optical modules miniaturized GBIC.
