Avalanche photodetector: ntes cov teeb liab meej

Avalanche photodetector: Ntes cov teeb liab meej meej

Ib qho ntaub ntawv ceev txog 10Gb ib ob kis mus rau hauv cov fibers optical. Cov teeb liab tsis muaj zog zoo li cov kab ntsaum hauv hiav txwv tob. Yuav ua li cas thiaj ntes tau thiab nthuav lawv kom meej? Rofea Optoelectronics' ROF-APR 10G high-speed Avalanche photodetector module tshiab yog qhov kev daws teeb meem tseem ceeb rau qhov teeb meem no. Nws tsis yog tsuas yog lub receiver xwb tab sis kuj yog lub "amplifier" muaj zog rau cov teeb liab optical, tsim tshwj xeeb los kov yeej cov kev txwv ntawm cov teeb liab optical ceev.

✅ Lub hauv paus av qeeg ceev ceev: Ua kom muaj kev teb ceev ceevphotodiode av qeeg(APD photodiode), zoo li lub photohunter ntse, ua rau muaj "avalanche effect" nyob rau hauv cov teeb liab tsis muaj zog, ua tiav qhov exponential ob npaug ntawm cov teeb liab qub.

✅ kev ua kom nrov qis: Lub tshuab ua kom nrov qis ua kom lub teeb liab tswj tau qhov sib piv ntawm lub teeb liab thiab lub suab nrov thaum lub sijhawm ua kom nrov, nrog cov ntsiab lus meej thiab sib txawv.

✅ Kev nkag tau yooj yim: Ob qho tib si ib hom thiab ntau hom fiber inputs tuaj yeem ua tau yooj yim, thiab SMA interface tso zis yog plug-and-play, ua rau nws yooj yim rau kev koom ua ke rau hauv koj lub system

✅ Kev ua tau zoo tshaj plaws: qhov nce siab thiab qhov rhiab heev ua kom cov teeb liab tsis muaj zog tsis muaj qhov chaw nkaum; Cov zis AC-coupled thiab qhov nce tiaj tus yam ntxwv muab lub hauv paus ruaj khov rau kev ua tiav tom ntej.

Kev piav qhia txog khoom

Lub ROF-APR-10G high-speed avalanche photodetector (APD photodetector) sib xyaw ua ke lub teeb liab avalanche photodiode (APD photodiode) uas teb tau sai thiab lub amplifier uas tsis nrov heev, ib hom/ntau hom fiber-coupled input, thiab SMA connector output. Nws muaj qhov nce siab, rhiab heev, AC-coupled output, thiab qhov nce tiaj tus. Nws feem ntau yog siv rau hauv cov kab ke xa xov fiber ntau ceev thiab kev nrhiav pom lub zog ceev thiab lwm yam teb.

Cov yam ntxwv ntawm cov khoom:

Ntau yam spectral: 1100-1650nm

InGaAs APD ntes

Kev rhiab heev: -26 DBM

Lub zog kho qhov muag saturated yog 1dBm

Nws koom ua ke lub preamplifier thiab lub voj voog boost

Cov teb thov:

Kev kuaj pom lub plawv dhia ceev ceev

Kev sib txuas lus ceev ceev ntawm qhov chaw optical

Kev sib txuas lus fiber ntau ceev ceev
