Iyo optical fiber transceiver module SFP inoshanda sei?

1. Chii chinonzi transceiver module?

Transceiver modules, sezita rinoratidza, ari bidirectional, uye SFP zvakare imwe yacho.Izwi rekuti "transceiver" mubatanidzwa we "transmitter" uye "receiver".Naizvozvo, inogona kuita semupepeti uye inogamuchira kumisikidza kutaurirana pakati pemidziyo yakasiyana.Inoenderana neiyo module ndiyo inonzi magumo, iyo iyo transceiver module inogona kuiswa.SFP modules ichatsanangurwa zvakadzama muzvitsauko zvinotevera.
1.1 Chii chinonzi SFP?

SFP ipfupi yeDiki Form-factor Pluggable.SFP ndeye yakajairwa transceiver module.SFP modules inogona kupa Gbit/s kumhanya kwekubatanidza kune network uye inotsigira multimode uye singlemode fibers.Iyo inonyanya kuzivikanwa mhando yemhando ndeye LC.Zvinotaridzika, mhando dzefiber dzinosungirirwa dzinogonawo kuonekwa nemuvara weSFP's pull tab, sezvinoratidzwa muMufananidzo B. Mhete yebhuruu inodhonza kazhinji inoreva single-mode cable, uye mhete yekudhonza inoreva multi-mode cable.Kune marudzi matatu eSFP modules akaiswa maererano nekumhanya kwekufambisa: SFP, SFP +, SFP28.
1.2 Ndeupi musiyano uripo pakati peQSFP?

QSFP inomirira "Quad Form-factor Pluggable".QSFP inogona kubata nzira ina dzakasiyana.Kufanana neSFP, ese ari maviri-modhi uye akawanda-modhi fibers anogona kubatanidzwa.Imwe neimwe chiteshi inogona kufambisa mareti edatha kusvika ku1.25 Gbit/s.Naizvozvo, iyo yakazara data data inogona kusvika ku4.3 Gbit/s.Paunenge uchishandisa QSFP + modules, mana chiteshi anogona zvakare kuunganidzwa.Saka, iyo data data inogona kusvika ku40 Gbit / s.
