Ka hui o BOSA:
Ua kapa ʻia ka ʻāpana hoʻomāmā i ka TOSA;
Ua kapa ʻia ka ʻāpana e loaʻa ana i ke kukui ʻo ROSA;
I ka hui ʻana ʻelua, kapa ʻia lāua ʻo BOSA.
Uila i Optical TOSA:
LD (Laser Diode) laser semiconductor, hoʻohana ʻia e hoʻololi i nā hōʻailona uila i nā hōʻailona opi no ka hoʻohana ʻana i nā pahu hoʻokuʻu ʻike.
Optical i ka ROSA uila:
PD Photo Dioder photodiode, hoʻohana ʻia no ka hoʻololi ʻana i nā hōʻailona māmā i kēia manawa, a laila hoʻololi ʻia i hōʻailona uila ma o ka mea hoʻonui impedance impedance (TIA).
Hiki ke hoʻohana ʻokoʻa ʻia ʻo TOSA a me ROSA e like me LC optical module a me SC optical module.Ke hoʻohana ʻia ʻo BOSA, hoʻohana maʻamau ia e like me SC optical module
ʻO ke koho ʻana o ka nui ma muli o ka nui maoli o kēia manawa a loaʻa iā ia kēia ʻike:
ʻO ka lua 10mil me ka 20mil PAD e pili ana i ke au o 0.5A no ka uea 20mil, a me ka puka 40mil me ka 40mil PAD pili i ke au o 1A no ka uea 40mil.Ke kiʻekiʻe ke koi o kēia manawa, hiki ke kau ʻia nā vias he nui i nā kūlana pili e hoʻonui i ka hiki ke lawe.ʻO ke kumukūʻai wili maʻamau no 30% a 40% o ke kumukūʻai hana PCB.
Ma ka noʻonoʻo ʻana i ke kumukūʻai a me ka maikaʻi o ka hōʻailona, ʻoi aku ka maikaʻi o ke koho ʻana i ka 10 / 20mil (drilling / soldering pad) no nā papa papa 6-10.No nā PCB kiʻekiʻe a me ka liʻiliʻi liʻiliʻi, hiki ke hoʻāʻo ʻia ka wili 8mil.ʻO ka liʻiliʻi liʻiliʻi e paʻakikī i ka hoʻokō ʻana i ke kaʻina hana, maʻalahi ka haki ʻana o ka drill bit, a piʻi ke kumukūʻai.ʻO ka maʻamau, koi nā hale hana papa i nā uku wili e uku ʻia no ka ʻeli ʻana ma lalo o 11.81mil.
Mai kahi hiʻohiʻona hoʻolālā, ʻo ka lua ma waena o ka lua wili waena a me ka pā solder a puni, ka mea e hoʻoholo ai i ka nui o ka lua wili.ʻOiai ka liʻiliʻi o ka nui o ka puka ma, ʻoi aku ka liʻiliʻi o ka capacitance parasitic, ʻoi aku ka maikaʻi o ka paʻa o nā hōʻailona wikiwiki.
I ka manawa like, ua kaupalena ʻia ka nui o ka puka ma ke kaʻina hana wili a me ka hana electroplating;ʻO ka liʻiliʻi o ka puka, ʻoi aku ka lōʻihi o ka manawa, a ʻoi aku ka maʻalahi o ka haʻalele ʻana mai ke kūlana waena.Ke ʻoi aku ka hohonu o ka wili ʻana (ma ka hohonu o ka lua ma kahi o 50mil) ma mua o 6 mau manawa o ka puka, ʻaʻole hiki ke hōʻoia i ka hoʻopaʻa ʻana i ke keleawe like ʻole ma ka paia o ka lua.No laila, ʻo ke anawaena wili liʻiliʻi i hiki i nā mea hana PCB ke hāʻawi ʻo 8mil.
ʻO ka mea i luna nei kahi ʻike pōkole o "Introduction to Key Parameters of BOSA - ma o ka nui (I)", hiki ke lilo i mea kuhikuhi no kēlā me kēia.Loaʻa i kā mākou hui kahi hui ʻenehana ikaika a hiki ke hāʻawi i nā lawelawe ʻenehana loea i nā mea kūʻai aku.I kēia manawa, loaʻa i kā mākou hui nā huahana like ʻole: naʻauaoonu, module optical communication, module fiber optical, sfp optical module, olt equipment, Ethernet switch and other network tools.Inā makemake ʻoe, hiki iā ʻoe ke aʻo hou e pili ana iā lākou.
