Fiber optic connector

1. Transmission mode

Inoreva nzira yekufambisa yechiedza mune optical fibers (electromagnetic field distribution form).Iyo inowanzoshandiswa kutaurirana fiber

mamodhi akakamurwa kuita imwechete modhi uye multimode, ine imwechete modhi yakakodzera kutapurirana kure-kure uye multimode yakakodzera

pfupi-renji kutapurirana.G652D single mode optical fibers ine core dhayamita d1 ye9 um uye cladding dhayamita d2 ye125 um.Multimode

optical fibers anowanzo kukamurwa kuita mafomu maviri: 62.5/125 kana 50/125.

Kusarudzwa kwe optical fiber modhi kunofanirwa kuenderana neiyo optical module, zvikasadaro zvinokonzeresa kurasikirwa nekuda kwepakati dhayamita kusawirirana.

Kubatana pakati pe optical fibers uye tambo dzine madhayamita akasiyana epakati hazvikurudzirwe.

2. Kuisa kurasikirwa

Huwandu hwekudzikisira kwemagetsi chiratidzo chemagetsi, chinowanzo ratidzwa mumadecibel, kana uchishandisa fiber optic zvibatanidza zvekubatanidza.Semuyenzaniso,

kana kurasikirwa kwekuisa kuri 3dB, iyo yekurasikirwa kwemagetsi inosvika makumi mashanu muzana.Kana kurasikirwa kwekuisa kuri 1dB, kurasikirwa kwemagetsi kunenge

20%, uye IL = - 10lg (yakabuda optical simba / input optical simba).

3. Dzorera kurasikirwa

Iyo inozivikanwawo seyekuratidzira kurasikirwa, inoreva paramende yechiratidzo chekuita kwechiratidzo.Echo kurasikirwa inotsanangura mari yakadzorerwa ne

optical chiratidzo painodzokera kunzira yekutanga.Kazhinji, iyo yakakura kukosha, zviri nani.Semuenzaniso, pakuisa 1mw simba, 10% yaro

inoratidzwa kumashure, inova 10dB, uye 0.003% inoratidzwa kumashure, zvichikonzera kurasikirwa kwemaungira kweinenge 45dB.RL=- 10lg (yakaratidza chiedza simba/

mwenje wekuisa simba)

4. Chiso chemhando

Optical fiber pamusoro pemhando dzakakamurwa kuita PC (spherical surface grinding) uye APC (oblique spherical surface grinding).Mushure me APC kugaya,

iro rinoratidzira mwenje mwenje rinodzoka munzira yepakutanga rakaderedzwa zvakanyanya, izvo zvinobatsira kuvandudza kurasikirwa kwekudzokera kwechibatanidza.
