Pehea ka hana ʻana o ka module SFP fiber transceiver module?

1. He aha ka transceiver module?

ʻO nā modula transceiver, e like me ka inoa e hōʻike nei, he bidirectional, a ʻo SFP kekahi o lākou.ʻO ka huaʻōlelo "transceiver" kahi hui o "transmitter" a me "receiver".No laila, hiki iā ia ke hana ma ke ʻano he transmitter a me kahi mea hoʻokipa e hoʻokumu i ke kamaʻilio ma waena o nā mea like ʻole.E pili ana i ka module ka mea i kapa ʻia he hopena, kahi e hiki ai ke hoʻokomo i ka module transceiver.E wehewehe ʻia nā modula SFP ma nā mokuna aʻe.
1.1 He aha ka SFP?

He pōkole ʻo SFP no Small Form-factor Pluggable.ʻO SFP kahi modula transceiver maʻamau.Hiki i nā modula SFP ke hāʻawi i nā pilina wikiwiki Gbit/s no nā pūnaewele a kākoʻo i nā fibers multimode a me singlemode.ʻO ke ʻano maʻamau maʻamau ʻo LC.I ka nānā 'ana, hiki ke 'ike 'ia nā 'ano fiber connectable e ke kala o ka SFP pull tab, e like me ka mea i hō'ike 'ia ma ka Figure B. 'O ke apo huki polū ma ke 'ano ma'amau, 'o ia ho'i ke kaula ho'okahi-mode, a 'o ke apo huki 'o ia ho'i ka uwea multi-mode.ʻEkolu ʻano o nā modula SFP i hoʻokaʻawale ʻia e like me ka wikiwiki o ka lawe ʻana: SFP, SFP +, SFP28.
1.2 He aha ka ʻokoʻa ma waena o QSFP?

Kū ʻo QSFP no "Quad Form-factor Pluggable".Hiki i ka QSFP ke hoʻopaʻa i ʻehā mau ala kaʻawale.E like me SFP, hiki ke hoʻohui ʻia nā fibers ʻelua-mode a me multi-mode.Hiki i kēlā me kēia kahawai ke hoʻouna i nā helu ʻikepili a hiki i 1.25 Gbit/s.No laila, hiki ke piʻi ka nui o ka ʻikepili i ka 4.3 Gbit/s.I ka hoʻohana ʻana i nā modula QSFP +, hiki ke hoʻopili pū ʻia nā kaha ʻehā.No laila, hiki ke piʻi ka helu ʻikepili i 40 Gbit/s.
