Ke hālāwai nā papahana nāwaliwali o kēia manawa i ka hoʻouna lōʻihi, hoʻohana pinepine ʻia nā fiber optics. Ma muli o ka lōʻihi o ka hoʻouna ʻana o ka fiber optical, ma ka laulā, ʻoi aku ka mamao o ka hoʻouna ʻana o ka fiber mode hoʻokahi ma mua o 10 mau kilomita, a ʻo ka mamao o ka hoʻouna ʻana o ka multi-mode fiber hiki ke piʻi i 2 mau kilomita.
Ma nā pūnaewele fiber optic, hoʻohana pinepine mākou i nā transceivers fiber optic. No laila, pehea e hoʻopili ai i nā transceivers fiber optic? E nānā pū kākou.
ʻO ka mea mua, ke kuleana o nā transceivers fiber optic
① Hiki i ka transceiver fiber optical ke hoʻonui i ka mamao o ka hoʻouna ʻana o Ethernet a hoʻonui i ka radius uhi o Ethernet.
② Hiki i ka transceiver fiber opticalhoʻololima waena o 10M, 100M a i ʻole 1000M Ethernet uila uila a me ka optical interface.
③ Me ka hoʻohana ʻana i nā transceivers fiber optic no ke kūkulu ʻana i kahi pūnaewele hiki ke mālama i ka hoʻopukapuka pūnaewele.
④ ʻO nā transceiver fiber Optical e hoʻolalelale i ka pilina ma waena o nā kikowaena, nā mea hou, nā hubs, nā terminals a me nā hopena wikiwiki.
⑤ Loaʻa i ka transceiver fiber optical kahi microprocessor a me kahi interface diagnostic, hiki iā ia ke hāʻawi i nā ʻike pili ʻikepili like ʻole.
ʻO ka lua, ʻo wai ka transceiver i loaʻa i ka transceiver optical a ʻo wai ka mea e loaʻa iā ia?
Ke hoʻohana nei i nā transceivers fiber optical, nui nā hoaaloha e hālāwai me nā nīnau penei:
1. Pono e hoʻohana i nā transceivers fiber optical i nā pālua?
2. Ua mahele ʻia ka transceiver fiber optical i hoʻokahi no ka loaʻa ʻana a hoʻokahi no ka lawe ʻana? A i ʻole hiki ke hoʻohana ʻia ʻelua mau transceiver optical ma ke ʻano he pālua?
3. Inā pono e hoʻohana ʻia nā transceivers fiber optical i ʻelua, pono anei lākou o ka momoku like a me ke ʻano hoʻohālike? A i ʻole hiki ke hoʻohana pū ʻia kekahi mau lama?
Pane: Hoʻohana mau ʻia nā transceivers fiber optic i nā pālua e like me nā mea hoʻololi photoelectric, akā hiki nō ke hoʻohui i nā transceivers fiber optic me ka fiber.nā hoʻololi, nā transceivers fiber optic a me nā transceivers SFP. Ma ke kumu, ʻoiai ʻo ka lōʻihi o ka nalu o ka hoʻouna ʻana i ka optical like ʻO ka hōʻailona encapsulation hōʻailona like a kākoʻo lāua ʻelua i kekahi protocol e hoʻokō i ke kamaʻilio fiber optical.
ʻO ka maʻamau, ʻaʻole hoʻokaʻawale ʻia nā transceivers i ka hopena hoʻouna a me ka hopena e loaʻa ai, a hiki ke hoʻohana ʻia i ka wā e ʻike ʻia ai i nā pālua.
ʻO kahi transceiver fiber hoʻokahi wale nō (pono ʻia hoʻokahi fiber no ke kamaʻilio maʻamau) e loaʻa ka hopena hoʻouna a me ka hopena loaʻa.
ʻO nā huaʻōlelo ʻē aʻe, ʻaʻole hiki ke kamaʻilio pū kekahi me nā helu like ʻole (100M a me Gigabit) a me nā lōʻihi nalu like ʻole (1310nm a me 1300nm). Eia kekahi, ʻoiai inā hoʻohui ʻia kahi transceiver fiber hoʻokahi a me kahi fiber pālua o ka brand like, ʻaʻole hiki ke kamaʻilio me kekahi. Interoperable.
No laila ʻo ka nīnau, he aha ka transceiver fiber hoʻokahi a he aha ka transceiver fiber pālua? He aha ka ʻokoʻa ma waena o lākou?
He aha ka transceiver fiber hoʻokahi? He aha ka transceiver pālua-fiber?
ʻO ka transceiver fiber hoʻokahi e pili ana i kahi uwea optical mode hoʻokahi. Hoʻohana ka transceiver fiber hoʻokahi i hoʻokahi kumu a ua pili nā hopena ʻelua i kēia kumu. Hoʻohana nā transceivers ma nā ʻaoʻao ʻelua i nā lōʻihi nalu optical ʻē aʻe, no laila hiki ke hoʻouna ʻia i hoʻokahi hōʻailona Māmā.
Hoʻohana ka transceiver pālua-fiber i ʻelua cores, hoʻokahi no ka hoʻouna ʻana a hoʻokahi no ka hoʻokipa ʻana, a pono e hoʻokomo ʻia kekahi ʻaoʻao ma kekahi ʻaoʻao, a pono e hoʻopaʻa ʻia nā ʻaoʻao ʻelua.
1.Single fiber transceiver
Pono ka transceiver fiber hoʻokahi e hoʻokō i ka hana hoʻouna a me ka hana hoʻokipa. Hoʻohana ʻo ia i ka ʻenehana multiplexing māhele hawewe e hoʻouna a loaʻa i ʻelua mau hōʻailona optical me nā lōʻihi hawewe like ʻole ma hoʻokahi fiber optical.
No laila, hoʻouna ʻia ka transceiver hoʻokahi-fiber mode hoʻokahi ma o ka fiber optical core, no laila e hoʻouna ʻia ka hoʻouna ʻana a me ka loaʻa ʻana o ke kukui ma o ka fiber core i ka manawa like. I kēia hihia, no ka hoʻokō ʻana i ke kamaʻilio maʻamau, pono e hoʻohana ʻia ʻelua mau nalu o ka mālamalama e ʻike.
No laila, ʻo ka module optical o kahi transceiver hoʻokahi-mode single-fiber he ʻelua mau nalu o ke kukui i hoʻokuʻu ʻia, maʻamau 1310nm / 1550nm. Ma kēia ala, aia nā ʻokoʻa ma waena o nā ʻaoʻao ʻelua o nā transceivers:
Hoʻouna ka transceiver ma kekahi hopena i 1310nm a loaʻa iā 1550nm.
ʻO ka hopena ʻē aʻe e hoʻopuka ana i ka 1550nm a loaʻa iā 1310nm.
No laila he mea maʻalahi i nā mea hoʻohana ke hoʻokaʻawale, a hoʻohana maʻamau i nā leka.
Ua puka mai ka A-terminal (1310nm / 1550nm) a me B-terminal (1550nm / 1310nm).
Pono nā mea hoʻohana e hoʻohana i ka pilina AB, ʻaʻole i ka pilina AA a i ʻole BB.
Hoʻohana wale ʻia ka hopena AB no nā transceivers fiber optic hoʻokahi.
2.Dual fiber transceiver
ʻO ka transceiver pālua-fiber he port TX (port transmitting port) a me kahi awa RX (receiving port). Hoʻouna nā awa ʻelua i ka lōʻihi nalu like o 1310nm, a ʻo 1310nm hoʻi ka hoʻokipa. No laila, ua hoʻopili ʻia nā ʻāpana optical parallel ʻelua i hoʻohana ʻia i ka uwea.
3. Pehea e hoʻokaʻawale ai i ka transceiver fiber hoʻokahi mai ka transceiver fiber pālua?
Aia i kēia manawa ʻelua ala e hoʻokaʻawale ai i nā transceivers hoʻokahi-fiber mai nā transceivers pālua-fiber.
①Ke hoʻokomo ʻia ka transceiver optical me kahi module optical, ua māhele ʻia ka transceiver optical i ka transceiver hoʻokahi-fiber a me ka transceiver pālua-fiber e like me ka helu o nā cores o ka mea lele optical fiber jumper. ʻO ka linearity o ka jumper fiber optical i hoʻopili ʻia i ka transceiver single-fiber (akau) he fiber core, nona ke kuleana no ka lawe ʻana a me ka loaʻa ʻana o ka ʻikepili; ʻO ka linearity ʻelua cores. Hoʻokahi kumu no ka lawe ʻana i ka ʻikepili a ʻo ke kumu ʻē aʻe ke kuleana no ka loaʻa ʻana o ka ʻikepili.
②Ke loaʻa ʻole i ka transceiver fiber optical kahi module optical i hoʻokomo ʻia, pono e hoʻokaʻawale i waena o kahi transceiver fiber hoʻokahi a me kahi transceiver fiber ʻelua e like me ka module optical i hoʻokomo ʻia. Ke hoʻokomo ʻia kahi module optical bidirectional single-fiber i loko o ka transceiver fiber optical, ʻo ia hoʻi, he ʻano simplex ka interface, ʻo ka transceiver fiber optical kahi transceiver fiber-fiber (kiʻi pololei); i ka wā e hoʻokomo ʻia ai kahi module optical bidirectional ʻelua-fiber i loko o ka transceiver fiber optical, ʻo ia hoʻi, i ka wā he ʻano duplex ka interface, ʻo kēia transceiver kahi transceiver pālua-fiber (kiʻi hema).
ʻO ka hā, ka hōʻailona a me ka pilina o ka transceiver fiber optical
1.Indicator of optical fiber transceiver
No ka hōʻailona o ka transceiver fiber optical, loaʻa iā mākou kahi ʻatikala mua i hoʻolaʻa ʻia i kēia ʻike.
Eia mākou e nānā hou ma o ke kiʻi i mea akaka.
