SFP-Transceiver: chinangwa, mifananidzo, zvinhu

Kuvandudza date kutapukirwa michina zvakakonzera kwaita faibha-optic network, izvo zvakafanira kubatanidza mudziyo kushandisa chinokosha midziyo - SFP-transceiver. SFP modules vakatsiva zvikuru yainetsa midziyo yaishandiswa GBIC uye telecommunication mitsetse vane nokukurumidza kudirana kupfuura 100 Mbit pasekondi yoga yoga.

ramangwana

SFP-transceivers anoshandiswa sezvo priemoperedatochnogo michina. Nemamwe mashoko, ivo vave vanozoshanda pakati faibha-optic waya kana hangaiwa unshielded vakamonyanisa, uye nomumbure kadhi mudziyo - chinja, router kana Modem. The chikuru mukana module connector iduku kwazvo. Nokuda kwaizvozvo, SFP-transceiver pamwe nenzvimbo yakaita masendimita 20 anogona kutakura 20 cheap car insurance.

The midziyo inoshandiswa nokuda yakakwirira date mwero (anopfuura 10 megabits por wechipiri) nokuti zvinotevera ruzivo: SDH uye Fiber Channel. Uyezve, vanhuwo zvokushandisa, izvo anokwanisa kubata mhando nhatu nhepfenyuro chiratidzo.

Mhando SFP-Transceiver

Zvichienderana basa, zvakadai faibha-optic waya, uyewo midziyo inoshandiswa, zvose SFP modules vakakamurwa maererano akawanda zvinodiwa:

1. The date chinja unodiwa. Average SFP-transceiver retransmits chiratidzo pa 100 Mb / s uye 1 Gbit / s, SFP + XFP zvinodiwa uye - kusvika 10 GB / s.
2. The mhando connector. SC-slots rinoshandiswa batanidza chimwe-internet wire, apo mabiko uye kupararira mashoko kunoitika imwe faibha, uye LC-connector - maviri-internet, apo mabiko uye kupararira anonongedzera rakatakurwa migero.
3. Mhando faibha. Kubatanidza kune chete waya inoshandiswa SM-transceiver uye multimode - MM modules.
4. Most simba chiratidzo zvitange. mamirire Izvi zvinosiyana munzvimbo siyana 1310 nm uye 1550 nm rimwe chete nzira kubatana, uye mukati 850 nm uye 1310 nm nokuda multimode netambo.

Mumwe SFP-Manyiminya transceiver ane imwe bhajeti, kana zvakawanda chiratidzo mabiko uye hutachiwana. Nokufamba chiedza kubudikidza waya ndiyo attenuated chiratidzo. Kusiyana kunonyanyisa daro kuti module anokwanisa kutuma chiratidzo uye nesimba vakapiwa chiedza zvinoyerera, anonzi Manyiminya bhajeti. Data izvi zvinoratidzwa umbowo pepa iri transceiver muna db.

Kushanda modules

Panguva date chinja SFP module inongorira chiratidzo chiedza muna asingaoneki chakarondedzera (pane chinokosha Laser kuti chinangwa ichi mukati midziyo). Naizvozvo zvachose hazvitenderwi kuti atarire "ziso" ari mudziyo kunzvenga kuvadza the retina.

Unobva SFP transceiver anofanira kupfeka rimwe chiningoningo rundarira, pashure unobatanidza kuti dzimba. Zvikasadaro, matsva ari electrostatic okuyerera anogona kukuvadza mudziyo.

Uyewo, "ziso" ari Laser inonyatsoziva guruva, saka regai kubvisa unodzivirira cover vasati kutendeukira pamusoro mudziyo kune zvakarukwa. Kurebesa basa module, chenjerera dzokubvisa waya kubva buda.

Selection Rules SFP-modules

Sarudza SFP-transceiver kunge maererano unhu hwako faibha-optic waya. Zvakakodzera nezvemuchato nyaya shoma. Chekutanga, zvinokosha kuti zvakarurama kuona Manyiminya bhajeti. Tinoratidza kushandisa chaiwo namano. Apo hapana, unogona kuwana kubva kukosha "anenge", zvakakwana kuziva daro pakati pfungwa kugamuchirwa uye kupararira kusvika imwe kiromita.

Chechipiri, kuziva mhando chihuri pamusoro bhodhi rako samambure mudziyo. Optical SFP transceiver anofanira kusarudzwa pamwe anawo zvechizarira. Zvikasadaro, iwe chete havazokwanisi kushandisa module. Pari kutengeswa anogona kuwanikwa nhumbi latches pakubhadhara matatu: Button, Mylar Tab, Bale-kirasipi. Unogona kuona mhando nemaziso.
