Kufotokozera kwaifupi:

MyLraning ™ rohs zogwirizana ndi 850nm zojambula 550m zimafikira kwambiri, ma module okwera okwera mtengo, okwera mtengo othandiza kuthandizidwa ndi ma inshuwaransi a 1.2550m ndi mmf. The transceiver imakhala ndi zigawo zitatu: Puble wa VCEL, pini ya vcsel, pini yolumikizidwa ndi tramplifier (Tia) ndi unit yoyang'anira. Ma module onse amakhutiritsa kalasi yanga. Makina ophatikizikawo ndi ogwirizana ndi mgwirizano wa sfp angapo (MSA) ndi sff-8472. Kuti mumve zambiri, chonde onani sfp msa.

Zolemba:

1. Mkuluyo, kutulutsa kumeneku kumawonetsa cholakwika cha mtundu wina. Kutsitsidwa kumawonetsa ntchito wamba. Ndipo iyenera kukokedwa ndi 4.7 - 10k

2. Tx Lement ndi cholowa chomwe chimagwiritsidwa ntchito kutseka zotulutsa zotulutsa zotulutsa. Imakokedwa mkati mwa gawo ndi 4.7 - 10k ness. Mayiko ake ndi awa:

Otsika (0 - 0.8v): Kutumiza pa (> 0,8, <2.0v): Osakhazikika

Okwera (2.0v ~ ~ ~ vcc + 0.3v): Transmitter yolumala: "kutumiza kwalumala

3. Mad-def 0,1,2. Awa ndi ma pini otanthauzira a Module. Ayenera kukokedwa ndi 4.7k - 10k gwiritsani ntchito bolodi. Mphamvu yamagetsi ikhale pakati pa 2,0V ~ vcc + 0.3v.

Mod-def 0 yakhazikika ndi gawo losonyeza kuti gawo limapezeka

Mod-def 1 ndi mzere wotchi ya waya wa waya wa seri ya seri

Mod-def 2 ndi mzere wa ma waya awiri a waya wa seri

4. Pakukwera, izi zimawonetsa kutayika kwa chizindikiro (Losa). Kutsitsidwa kumawonetsa ntchito wamba.

5. Rd +/-: awa ndi zotulutsa zina. Amakhala mizere yosiyanasiyana yosiyanasiyana yomwe iyenera kuyimitsidwa ndi 100ω (yosiyanitsa) pa serses. Kuphatikizika kwa Ac kumachitika mkati mwa gawo ndipo sikufunikira pa bolodi.

6. TD +/: Awa ndi kulowetsa kosiyana. Amakhala ndi mizere yosiyanasiyana yosiyanasiyana yosiyanasiyana ya 100ω yosiyanasiyana mkati mwa gawo. Kuphatikizika kwa Ac kumachitika mkati mwa gawo ndipo sikufunikira pa bolodi.
