SFP-Transceiver: injongo, iintlobo, iimpawu

Ukuphucula technologies transmission data kukhokelele ukuvela kothungelwano fibre-optic, apho kuyimfuneko ukwazi ukuqhagamshela ifowuni ukusebenzisa izixhobo ezikhethekileyo - SFP-transceiver. Iimodyuli SFP ithabatha indawo izixhobo nzima ezisetyenziswa imigca GBIC kunye nokunxibelelana ngefoni kunye kwisantya ungqamanisa ngaphezulu kwe 100 Mbit ngomzuzwana.

nomgomo

SFP-transceiver zisetyenziswa izixhobo priemoperedatochnogo. Ngamanye amazwi, benza njengoko njengabalamli phakathi fibre-optic cable okanye isibini unshielded nesijijekileyo, nengcinga ikhadi womnatha - nokucima, umzila okanye modem. Inzuzo ephambili Isidibanisi umnqongo mncinane kakhulu. Ngenxa oku, SFP-transceiver kunye ububanzi 20 cm inokuthatha ukuya kwiindawo zokubeka-20.

Ezi zixhobo kusetyenziswa izinga eliphezulu data (megabits ngaphezu kwe-10 ngomzuzwana) ngenxa ubugcisa zilandelayo: SDH kunye Fibre Channel. Ukongeza, izixhobo eqhelekileyo, onako ukusingatha iintlobo ezintathu umqondiso losasazo.

Iintlobo SFP-Transceiver

Kuxhomekeka msebenzi, ezifana fibre-optic cable, kwakunye nezixhobo ezisetyenziswayo, yonke iminqongo SFP yahlulwe ngokwemimiselo ezininzi:

1. Izinga transfer data. Umyinge SFP-transceiver retransmits uphawu kwi 100 Mb / s kunye 1 Gbit / s, imilinganiselo SFP + XFP ne - ukuya kwi-10 GB / s.
2. Uhlobo isinxibelelanisi. SC-slot osetyenziswayo ukudibanisa intambo olunye-ifayibha, apho ulwamkelo kunye nokusasazwa kolwazi lwenzeka kwi ifayibha mnye, kunye LC-isinxibelelanisi - kuba ifayibha-mbini, apho ulwamkelo kunye nokudlulisela lwemiqondiso baqhubeka imiphantsi.
3. Uhlobo ifayibha. To connect ku kwicingo single isetyenziswa SM-transceiver kunye multimode - iimodyuli MM.
4. amandla Uninzi uphawu ngesondo. Olu phawu kuyahlukana kuluhlu 1310 NM kwaye 1550 NM ukuxhumeka olunye-imowudi, nangaphaya 850 NM kwaye 1310 NM ngenxa iintambo multimode.

transceiver nganye SFP-enombala uba imali ethile, okanye uluhlu reception isignali transmission. Ngenxa sicatshulwa yokukhanya ngokusebenzisa le ntambo umqondiso okuncitshiswe. Umahluko phakathi komgama iphezulu ukuba modyuli nako ukuthumela umqondiso kunye namandla wobhobhozayo ukukhanya ezifunyenweyo, yaye kuthiwa mali optical. Ezi data kubonisiwe kuxwebhu idatha transceiver kwi dB.

Ukusebenza kwiimodyuli

Ngexesha ukudluliselwa kwedata umnqongo SFP ikhala ukukhanya uphawu kwi spectrum ongabonakaliyo (kukho laser ekhethekileyo le njongo ngaphakathi izixhobo). Ngoko ke akuvumelekanga ngokungqongqo ukuba bakhangele "iliso" zecebo ukunqanda umonakalo retina.

Ukuqhagamshela SFP transceiver kufuneka banxibe i isongo iwotshi, emveni uyidibanise kwi izindlu. Kungenjalo, le yangoku yokumpompoza electrostatic kungonakalisa sixhobo.

Ukongeza, i "iliso" lwe laser uvakalelo eluthulini, ngoko musa ukususa iziciko zokhuselo phambi kokuba isixhobo kwinethiwekhi. Ukuze kunaba mnqongo inkonzo, kulumkele ukuba ndikhuphe intambo ngokungeyomfuneko.

Rules Ukhetho SFP-iimodyuli

Khetha i SFP-transceiver kufuneka ihambelane iimpawu fibre-optic cable yakho. Kuyimfuneko ukuba sigxile imiba embalwa. Okokuqala, kufuneka ikwazi ukubonisa ngokuchanekileyo ukuba loo mali optical. Sicebisa usebenzise izixhobo ezikhethekileyo. Apho kukho namnye, unako ukufumana phandle ukubaluleka "malunga", kwanele ukuba ukwazi umgama phakathi ingongoma ulwamkelo kunye nokusasazwa ukuya ngekhilomitha.

Okwesibini, amisele uhlobo Kwasika esiswini ebhodini yesixhobo yakho womnatha. Optical SFP transceiver kufuneka zikhethwe kunye kanye lock efanayo. Kungenjalo, ukuba nje uza kuba nako ukusebenzisa le modyuli. Okwangoku kwimarike inokufumaneka izixhobo kunye latches kweentlobo ezintathu: Button, Mylar Tab, Bale-ndibambelela kuwe. Unakho ukubona uhlobo abangaboniyo.
