Cov zis hluav taws xob kho qhov muag (Output Power) yog hais txog qhov nruab nrab tso zis hluav taws xob kho qhov muag ntawm lub teeb pom kev ntawm qhov xa tawm kawg ntawm qhov kho qhov muag module, tseem hu ua qhov tso zis hluav taws xob kho qhov muag, uas tuaj yeem nkag siab raws li qhov siv ntawm lub teeb.
Formula: P(dBm)=10Log(P/1mW)
Chav tsev yog W lossis mW lossis dBm. (Qhov twg W los yog mW yog linear unit thiab dBm yog logarithmic unit.) Hauv kev sib txuas lus, peb feem ntau siv dBm los qhia lub hwj chim kho qhov muag.
Qhov loj dua tus nqi hluav taws xob kho qhov muag, lub zog siv hluav taws xob ntau dua ntawm qhov hluav taws xob optical emission. Tab sis nws tsis tau txhais hais tias qhov siab dua qhov kho qhov muag lub hwj chim, qhov zoo dua. Txhua lub cuab yeej kho qhov muag muaj lub zog ruaj khov overload optical, thiab lub zog kho qhov muag ntau dhau yuav ua rau muaj qhov yuam kev me ntsis. Feem ntau, lub zog kho qhov muag ntawm SFP module yog nyob nruab nrab ntawm -2 thiab -13dbm, thiab cov nqi ntau kuj tseem yuav hloov nrog cov kis tau tus mob.
Muaj overload optical hwj chim, thiab tseem muaj rhiab heev (qhov tsawg kawg nkaus kho qhov muag fais fab kev sib txuas lus tus nqi). Thaum lub zog hluav taws xob xa hluav taws xob tsawg dhau lawm, lub zog kho qhov muag tau txais ntawm qhov kawg ntawm lub module yuav tsawg dua qhov tau txais rhiab heev ntawm lub module, thiab lub module tsis tuaj yeem txais lub teeb liab ib txwm.
Thaum lub zog hluav taws xob xa hluav taws xob loj dhau lawm, txawm hais tias lub attenuator tuaj yeem ntxiv rau ntawm qhov kawg tau txais kom ua tiav qhov tau txais lub zog kho qhov muag ntawm qhov tau txais qhov kawg, qhov kev xav tau tam sim no tseem yuav loj dhau, uas yuav cuam tshuam rau cov teeb liab kis tau zoo thiab kev pab lub neej ntawm lub module.
Cov saum toj no yog cov kev taw qhia ntawm lub laser hom SFP modules coj los ntawm Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. e module khoom tsim los ntawm lub tuam txhab npogoptical fiber modules, Ethernet modules, optical fiber ntau transceiver modules, optical fiber nkag modules, SSFP optical modules, thiabSFP optical fibers, lwm.
Tag nrho cov khoom lag luam saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Ib pab neeg R & D muaj zog thiab muaj zog tuaj yeem pab cov neeg siv khoom nrog cov teeb meem kev lag luam, thiab pab pawg ua lag luam xav tau zoo tuaj yeem pab cov neeg siv khoom tau txais kev pabcuam zoo thaum lub sijhawm sib tham ua ntej.
thiab ua haujlwm tom qab tsim khoom. Zoo siab txais tos koj tiv tauj peb rau txhua yam kev nug.
