Kungani amamojula we-SFP optical edumile?

Ivolumu yeImodyuli ye-SFP ye-opticaliyancipha ngesigamu uma iqhathaniswa nevolumu ye-GBIC optical module. Inombolo yezimbobo ze-SFP kuphaneli efanayo izoba kabili kunaleyo ye-GBIC optical module. I-module ye-SFP optical efanayo ine-plug-and-play mini optical fibre slot, ehambisana nedatha Ngezidingo zokuminyana okuphezulu phakathi nendawo, amamojula optical SFP azothatha indawo ye-GBIC optical modules ezikhungweni zedatha esikhathini esizayo.

Amamojula we-SFP optical adumile

Ngenxa yokuthi amamojula we-SFP optical we-GLC-BX-D ne-GLC-BX-U anamandla futhi afunwa kakhulu, lezi zinhlobo ezimbili zamamojula optical zisekela ukuqapha kwedatha, okuvumela abasebenzisi ukuthi baqaphe ukusebenza kwamamojula optical ngesikhathi sangempela, njenge izinga lokushisa lokulandela umkhondo, ukukhanya kwamandla okukhiphayo, amandla okufaka optical, i-laser bias current, i-transceiver power supply voltage, njll. Ngaphezu kwalokho, I-1000BASE-BX10-D SFP optical module enebanga lika-10km, iGLC-BX40-D SFP optical module enebanga elingu-40km, kanye neGLC-BX80-D SFP optical module enebanga lika-80km. phakathi kwabasebenzisi.

I-SFP Optical module inezinzuzo ezine ezilandelayo:

1. Isekela ukushintshashintsha okushisayo, okunganciphisa ukufakwa, ukugcinwa nokuphatha isikhathi;

2. Ichweba liyavumelana nezimo;

3. Umklamo oqinile uthuthukisa ukwethembeka;

4. Sekela umsebenzi we-digital optical monitoring (DOM).

Ukusetshenziswa kwe-SFP optical module

1. Izintambo zenethiwekhi zamabanga amafushane I-1000BASE-T SFP optical module isekela i-10/100/1000 eguquguqukayo kanye ne-Auto MDI/MDIX, futhi ingasetshenziswa nesigaba sesi-5 sezintambo zezichibi zenethiwekhi ezingavinjiwe; ibanga lokudlulisela lingafinyelela ku-100m. I-1000BASE-SX SFP optical module iyahambisana ne-IEEE 802.3z 1000BASE-SX ejwayelekile, futhi ingasetshenziswa ku-50μm/62.5μm isixhumanisi se-multimode fiber enebanga eliphakeme lokudlulisela elingu-550m.

2. Izintambo zenethiwekhi zamabanga amade I-1000BASE-EX kanye ne-1000BASE-ZX SFP amamojula optical angasetshenziswa nge-single-mode optical fibers futhi afanele ukudluliswa kwenethiwekhi okude. Ibanga lika-1000BASE-EX SFP optical module lingafinyelela ku-40km, kanti ibanga lokudlulisela elingu-1000BASE-ZX SFP optical module lingafinyelela ku-80km.

Qaphela: Uma i-fiber yemodi eyodwa (i-SMF) isetshenziselwa ibanga elifushane, ukuze ugweme ukugcwala kakhulu kowamukelayo, i-optical attenuator idinga ukufakwa kusixhumanisi. Ngemva kokwethulwa kohlelo olungenhla, ingabe uthola ukuthi imbobo ye-SFP ingasekela womabili amamojula we-SFP kagesi we-port kanye namamojula we-SFP optical port? Kungakhathaliseki ukuthi izimbobo ze-SFP namamojula we-SFP optical ane-flexible ephezulu nokuhambisana kanjani ezinhlelweni zokusebenza ezingokoqobo, Isixazululo sakho esihle kakhulu se-Gigabit Ethernet.
