SFP-Transceiver cholinga, mitundu, mbali

Kuwonjezera deta kufala umisiri kwachititsa kuti zikamera wa maukonde CHIKWANGWANI-chamawonedwe chimene chili chofunika kulumikiza chipangizo ntchito zipangizo zina zapadera - SFP-transceiver. SFP zigawo m'malo zida zambiri wolemera ntchito GBIC ndi telefoni mizere ndi liwiro akukhamukira kuposa 100 Mbit pa mphindi.

tsogolo

SFP-transceivers ntchito ngati zida priemoperedatochnogo. M'mawu ena, iwo amachita intermediaries pakati pa chingwe CHIKWANGWANI-chamawonedwe kapena unshielded anapotoza awiri, ndipo maukonde khadi chipangizo - lophimba, rauta kapena modemu. Ubwino waukulu wa cholumikizira gawo ndi laling'ono kwambiri. Chifukwa ichi, SFP-transceiver ndi m'lifupi masentimita 20 akhoza kumakhalamo 20 mipata.

Zipangizo ntchito mlingo mkulu deta (kuposa 10 megabits pa chachiwiri) cha umisiri zotsatirazi: SDH ndi CHIKWANGWANI Channel. Komanso, zida wamba, amene angakonze mitundu itatu Kuwulutsa chizindikiro.

Mitundu ya SFP-Transceiver

Malinga ntchito, monga CHIKWANGWANI-chamawonedwe chingwe, komanso zida ntchito, zigawo zonse SFP zidzasankhidwa malinga ndi muyezo zingapo:

1. Mtokoma deta. Avereji SFP-transceiver retransmits mbendera pa 100 MB / s 1 Gbit / s, mfundo SFP + XFP ndi - 10 GB / s.
2. Mtundu wa cholumikizira. SC-kagawo ntchito kulumikiza lokhala ndi CHIKWANGWANI chingwe, kumene phwando ndi kufala kwa mudziwe limapezeka pa CHIKWANGWANI wina, ndipo LC-cholumikizira - awiri-CHIKWANGWANI, kumene phwando ndi kufala kwa chizindikiro ikuchitika padziko mitsinje.
3. Mtundu wa CHIKWANGWANI. Kulumikiza ku waya limodzi ntchito SM-transceiver ndi multimode - MM zigawo.
4. mphamvu kwambiri a mbendera opatsirana. Mkhalidwe umenewu zimasiyanasiyana mu osiyanasiyana 1310 nm ndi 1550 nm kugwirizana osakwatiwa-mode, ndipo mkati 850 nm ndi 1310 nm kwa zingwe multimode.

Aliyense transceiver SFP-kuwala ali bajeti ena, kapena osiyanasiyana phwando mbendera ndi HIV. Ndi ndime ya kuwala chingwe ndi attenuated chizindikiro. Kusiyana pakati pa mtunda pazipita kuti gawo amatha kutumiza mbendera ndi mphamvu ya analandira kamwazi kuwala, ndipo amatchedwa bajeti kuwala. deta izi zili pepala deta ya transceiver mu DB.

Kugwira ntchito ndi zigawo

Pa ukuthamana SFP gawo limatulutsa kuwala chizindikiro mu sipekitiramu oneka (pali laser wapadera kwa cholinga ichi mkati zipangizo). Choncho koletsedwa kusuzumiramo "diso" chipangizo kupewa kuwonongeka kwa diso.

Polumikiza SFP transceiver ayenera kuvala ndi dzanja chibangili, pambuyo ochilumikiza ku nyumba ya. Apo ayi, panopa kumaliseche kwa electrostatic akhoza kuwononga chipangizo chamagetsi lapansi.

Komanso, "diso" la laser ndi yovuta kwa fumbi, kotero musati kuchotsa chimakwirira zoteteza pamaso homuweki chipangizo maukonde. Kuti tidzakhale ndi gawo utumiki, samalani kuti wachotsa chingwe kuchokera poponya.

Kusankha Malamulo SFP-zigawo

Sankhani SFP-transceiver ayenera kukhala mogwirizana ndi makhalidwe a anu chingwe CHIKWANGWANI-chamawonedwe. M'pofunika kuganizira mavuto angapo. Choyamba, m'pofunika molondola kudziwa bajeti kuwala. Mpofunika pogwiritsa ntchito zipangizo zapadera. Kodi palibe, mungathe kupeza phindu "pafupifupi", ndi okwanira kudziwa mtunda pakati pa mfundo phwando ndi kufala kwa mpaka kilometre a.

Chachiwiri, kudziwa mtundu wa latch pa gulu la chida chanu maukonde. Kuwala SFP transceiver ayenera anasankha ndi ndendende loko chomwecho. Kupanda kutero, inu basi sangathe kugwiritsa ntchito gawo. Panopa pa msika angapezeke zida ndi latches a mitundu itatu: Button, Mylar Tab, Bale-Clasp. Mukhoza kudziwa mtundu wa zowoneka.
