(i) Loʻihi nalu waena
ʻO ka lōʻihi hawewe hana o ka module optical he laulā maoli, akā e ʻike ʻia nā ʻokoʻa ma waena o ke ʻano hoʻokahi a me ke ʻano multi-mode. A laila ua kapa ʻia ka ʻōlelo e like me ka lōʻihi o ka nalu waena.
ʻO ka ʻāpana o ka nalu waena he nanometer (nm),
ʻO nā lōʻihi nalu waena he 850nm, 1310nm a me 1550nm, etc.
1) 850nm (MM, multi-mode, kumu kūʻai haʻahaʻa (ʻoi aku ka liʻiliʻi o nā ʻāpana optika) akā pōkole ka mamao o ka hoʻouna ʻana (multi-mode transmission, hoʻololi like ma waena o nā lōʻihi nalu like ʻole), maʻamau wale nō 500m a 3KM);
2)1310nm (SM, hoʻokahi-mode, pohō nui i ka wā o ka hoʻouna ʻana, maʻalahi ke komo i ka ikehu ma ka liʻiliʻi liʻiliʻi liʻiliʻi, hoʻohana maʻamau no ka lawe ʻana i loko o 40km);
3)1550nm (SM, hoʻokahi-mode, pohō liʻiliʻi akā hoʻopuehu nui i ka wā o ka hoʻouna ʻana, hoʻohana maʻamau no ka lawe lōʻihi ma luna o 40km, a hiki i 120km me ka ʻole o ka relay).
(ii) Ka mamao hoʻouna
No ka mea, loaʻa i ka fiber optical nā hopena ʻaoʻao e like me ka dispersion, ka poho, a me ka hoʻokomo ʻana i ka nalowale i ka hōʻailona optical. No laila, ʻokoʻa nā mamao i hoʻopuka ʻia e nā ʻano kumu kukui like ʻole. I ka hoʻohui ʻana i nā mea hoʻokalakupua, koho i nā modules optical a me nā fiber optical e like me ka mamao loa o ka lawe ʻana i ka hōʻailona. Hoʻokaʻawale ʻia ka mamao o ka lawe ʻana o ka module optical i ʻekolu mau ʻano: ka lōʻihi pōkole, ka mamao waena a me ka lōʻihi. Manaʻo maʻamau ʻo 2km a ma lalo he mau mamao pōkole, 10 a 20km ka mamao waena, a ʻo 30km a ma luna he mamao lōʻihi.
(iii) Ka helu hoʻouna
ʻO ka helu hoʻouna e pili ana i ka helu o nā bits (bits) o ka ʻikepili i hoʻouna ʻia i kēlā me kēia kekona, ma bps. ʻO ka haʻahaʻa o ka hoʻouna ʻana he 100M, a hiki i 400Gbps, a ʻo ka helu hoʻohana maʻamau ʻo 155Mbps, 1.25Gbps, 10Gbps, 25Gbps, 40Gbps, 100Gbps a pēlā aku. Eia kekahi, ʻekolu mau helu o 2Gbps, 4Gbps a me 8Gbps optical modules i loko o ka ʻōnaehana mālama optical (SAN).
ʻO ka mea i luna nei ka ʻike o nā param nui ʻekolueter o nā modules optical i lawe ʻia e Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. ʻO nā huahana module i hana ʻia e ka uhi ʻoihana nā modules fiber optical, Nā modules Ethernet, nā modules transceiver fiber optical, nā modules komo fiber optical, SSFP mau modula optical, aʻO nā fiber optical SFP, etc. Hiki i nā huahana module i luna ke hāʻawi i ke kākoʻo no nā hiʻohiʻona pūnaewele like ʻole. Hiki i kahi hui R&D ʻoihana a ikaika ke kōkua i nā mea kūʻai aku me nā pilikia ʻenehana, a hiki i kahi hui ʻoihana noʻonoʻo a ʻoihana ke kōkua i nā mea kūʻai aku e loaʻa nā lawelawe kiʻekiʻe i ka wā o ka kūkākūkā mua a me ka hana ma hope o ka hana. Welina mai iā ʻoe kāhea iā mā˚ou no kēlā me kēia ʻano nīnau.
