    ʻIke pili i ka Module SFP

    Ka manawa hoʻouna: Oct-29-2021

    Aia ka SFP Module me ka mea ʻike maka, kaʻapuni hana a me ka interface optical. ʻO ka mea optical e pili ana i ka lawe ʻana a me ka loaʻa ʻana o nā ʻāpana.

    ʻO ka ʻāpana hoʻouna: ʻo ka hoʻokomo ʻana o kahi helu helu helu o nā hōʻailona uila, ma o ka hoʻoili ʻana o nā mea hoʻokele o loko, ka hoʻokele semiconductor laser (LD) o ka light emitting diode (LED) e hoʻouna aku i ka hōʻailona optical modulation code rate, māmā i loko. hāʻawi ʻia me kahi kaapuni mana hoʻolako uila. Paʻa mau ka mana hōʻailona optical.

    ʻO ka ʻāpana e loaʻa ana: ua hoʻololi ʻia ka module hoʻokomo hōʻailona optical o kekahi helu helu helu i hōʻailona uila ma o ka diode ʻike maka. Ma hope o ka preamplifer, ʻo ka hōʻailona hoʻopuka o ka bit rate pili i ka pae PECL. Ke emi mai ka mana opitika hoʻokomo ma mua o kekahi waiwai, hoʻokumu ʻia kahi hōʻailona hōʻailona.

    Nā ʻāpana a me ke ʻano o nā modules optical

    Ua loaʻa i nā modula Optical kekahi mau palena ʻenehana optical koʻikoʻi. Eia naʻe, no ka GBIC a me ka SFP hot-plug SFP Modules, pono ʻoe e hoʻolohe i nā ʻāpana ʻekolu.

    Ma muli o ka nanometer(nm), ʻekolu mau ʻano nui i kēia manawa.

    850nm (MM, multi-mode, haʻahaʻa haʻahaʻa akā pōkole ka mamao hoʻouna, maʻamau 500M wale nō).

    1310nm (SM, Single Mode, liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi, hoʻopuehu nui, hoʻohana maʻamau no ka lawe lōʻihi ma luna o 40KM, ʻaʻohe relay hiki ke hoʻouna pololei iā 120KM).

    1550nm (SM, Single Mode, liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi, hoʻopuehu nui, hoʻohana maʻamau no ka lawe lōʻihi ma luna o 40KM, ʻaʻohe replay e hoʻouna pololei iā 120KM).

     Ka Laki Hoolaha

    Ka helu o nā bits (BPS) o ka ʻikepili i hoʻouna ʻia i kēlā me kēia kekona.

    I kēia manawa. ʻEhā mau SFP Module maʻamau. 155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps a pēlā aku. ʻO ka uku hoʻoili maʻamau ke kūpono i hope. No laila, ua kapa ʻia ka 155M SFP Module he FE (100Mbit/s) SFP Module, a ʻo ka 1.25G SFP Module i kapa ʻia ʻo GE (Gigabit) optical module.

    ʻO kēia ka SFP i hoʻohana nui ʻia i nā lako uila optical. Eia kekahi, ʻo kāna helu hoʻouna i nā ʻōnaehana mālama fiber optic (SAN) he 2Gbps, 4Gbps, a me 8Gbps.

    Ka mamao hoʻouna

    ʻAʻole pono e hoʻokuʻu ʻia ka hōʻailona Optical i kahi mamao i hiki ke hoʻouna pololei ʻia. I nā kilomika ( i kapa ʻia ʻo kilomika, KM). ʻO nā kikoʻī o nā Module SFP penei: Multi-Mode 550M, Single-Mode 15KM, 40KM, 80KM, a me 120KM, etc.
