Vamwe vatengi havagone kuve nechokwadi kuti ndeipi mhando ye multimode fiber yavanoda kusarudza.Pazasi pane zvinyorwa zvemhando dzakasiyana dzereferensi yako.
Kune akasiyana mapoka egiredhi-index multimode girazi fiber tambo, kusanganisira OM1, OM2, OM3 uye OM4 tambo (OM inomirira optical multi-mode).
OM1 inotsanangura 62.5-micron tambo uye OM2 inotsanangura 50-micron tambo.Izvi zvinowanzo shandiswa munzvimbo dzekushandisa kune mapfupi kusvika 1Gb/s network.Asi OM1 uye OM2 tambo haina kukodzera kune yanhasi yepamusoro-kumhanya network.
OM3 uye OM4 ese ari maviri-laser-optimized multimode fiber (LOMMF) uye akagadziridzwa kuti agare nekukurumidza fiber optic network senge 10, 40, uye 100 Gbps.Ose ari maviri akagadzirirwa kushandiswa ne850-nm VCSELS (vertical-cavity surface-emitting lasers) uye ane aqua sheaths.
OM3 inotsanangura 850-nm laser-optimized 50-micron tambo ine inoshanda modal bandwidth (EMB) ye2000 MHz/km.Inogona kutsigira 10-Gbps yekubatanidza kureba kusvika ku300 metres.OM4 inotsanangura yakakwira-bandwidth 850-nm laser-yakagadziridzwa 50-micron tambo inoshanda modal bandwidth ye4700 MHz/km.Inogona kutsigira 10-Gbps yekubatanidza kureba kwe550 metres.100 Gbps nhambwe i100 metres uye 150 metres, zvichiteerana.
