No nā transceivers optical, inā ʻoi aku ka maikaʻi o ka fiber hoʻokahi a i ʻole ka fiber pālua, e hoʻomaopopo mua kākou i ke ʻano o ka fiber hoʻokahi a me ka fiber pālua.

Hoʻokahi fiber: Hoʻouna ʻia ka ʻikepili i loaʻa a hoʻouna ʻia ma hoʻokahi fiber optical.
ʻElua fiber: Hoʻouna ʻia ka ʻikepili i loaʻa a hoʻouna ʻia ma nā fiber optical ʻelua-core.

ʻOi aku ke kumukūʻai o nā modules optical bidirectional single-fiber, akā hiki ke mālama i hoʻokahi punawai fiber, ʻoi aku ka maikaʻi no nā mea hoʻohana me ka lawa ʻole o nā kumuwaiwai fiber.
He mea maʻalahi ka module dual-fiber bidirectional optical module, akā pono hoʻokahi fiber hou.Inā lawa nā kumuwaiwai fiber, hiki iā ʻoe ke koho i kahi module optical dual-fiber.

No laila, hoʻi i ka nīnau mua, ʻoi aku ka maikaʻi o ka fiber hoʻokahi a i ʻole ka fiber pālua no ka transceiver optical?

Hiki i nā transceivers optical fiber hoʻokahi ke mālama i ka hapalua o nā kumuwaiwai fiber cable, ʻo ia hoʻi, ka hoʻouna ʻana i ka ʻikepili a me ka hoʻokipa ʻana ma ka fiber hoʻokahi, kūpono loa i nā wahi i paʻa nā kumuwaiwai fiber;ʻoiai pono nā transceivers optical ʻelua-fiber e noho i ka fiber optical ʻelua, hoʻohana ʻia hoʻokahi kumu no ka hoʻouna ʻana (Tx) Hoʻohana ʻia kekahi kumu no ka loaʻa ʻana (Rx).ʻO nā hawewe nalu maʻamau o nā transceivers optical fiber hoʻokahi he 1310nm a me 1550nm no ka hoʻohana paʻa ʻana, ʻo ia hoʻi, ʻo 1310 ka lōʻihi o ka hawewe, a ʻo ka hopena ʻē aʻe he 1550 ka nalu, hiki ke hoʻouna a loaʻa paha.

Loaʻa i nā transceivers optical dual-fiber ka lōʻihi hawewe like, ʻo ia hoʻi, hoʻohana nā mea hana ma nā ʻaoʻao ʻelua i ka lōʻihi like.Eia nō naʻe, no ka mea ʻaʻohe paona honua i hui pū ʻia no nā huahana transceiver optical, aia paha ka like ʻole ma waena o nā huahana o nā mea hana like ʻole ke pili lākou.Eia kekahi, ma muli o ka hoʻohana ʻana i ka multiplexing māhele hawewe, ʻo nā huahana transceiver optical single-fiber i nā pilikia attenuation hōʻailona, ​​a ʻoi aku ka maikaʻi o ko lākou kūpaʻa ma mua o nā huahana pālua-fiber, ʻo ia hoʻi, ʻoi aku ka kiʻekiʻe o nā transceiver optical fiber hoʻokahi. No laila, ʻoi aku ka pipiʻi o nā transceivers optical fiber hoʻokahi ma ka mākeke.

Loaʻa i ka transceiver multi-mode nā ʻano hoʻoili he nui, ʻano pōkole ka mamao o ka lawe ʻana, a loaʻa i ka transceiver hoʻokahi-mode hoʻokahi wale nō;lōʻihi ka mamao o ka lawe ʻana.ʻOiai ke hoʻopau ʻia nei ka multi-mode, aia nō ka nui o nā noi i ka nānā ʻana a me ka hoʻouna ʻana i kahi pōkole ma muli o ke kumukūʻai haʻahaʻa.Hoʻopili nā transceivers multi-mode i nā fibers multi-mode, a kūpono hoʻi ke ʻano hoʻokahi a me ke ʻano hoʻokahi.ʻAʻole hiki ke hui pū ʻia.

I kēia manawa, ʻo ka hapa nui o nā transceivers optical ma ka mākeke he mau huahana pālua-fiber, he ʻano oʻo a paʻa, akā makemake i nā kumuwaiwai optical cable.
