RJ yog qhov luv luv ntawm Sau Npe Nkaus, uas txhais tau tias" sau npe ntsawb" ;. Lub ntsiab lus hauv FCC (Tsoom Fwv Tebchaws Txoj Haujlwm Sib Txuas Lus Kev Sib Tham thiab Txoj Cai Tswjfwm) yog tias RJ yog ib qho kev sib tham piav qhia txog kev sib txuas lus hauv zej tsoom kev sib txuas lus. Nquag siv yog RJ-11 thiab RJ-45. RJ-45 rau lub khoos phis tawj sib txuas yog tus qauv 8-ntsis modular interface. Feem ntau paub.
Yav dhau los plaub hom, tsib hom, super tsib hom, thiab rau (6) hom kab hlau, RJ-hom cuam tshuam yog siv. Hauv xya hom hluav taws xob thaiv kab hluav taws xob," tsis-RJ hom" Yuav muaj kev cuam tshuam. Piv txwv, thaum Lub Xya hli ntuj 30, 2002, TERA hom xya txuas txuas tsim los ntawm Simon tuam txhab raug xaiv raws li" tsis-RJ" hom xya txheem kev lag luam interfaces Txheem hom. Qhov xa cov kis ntawm cov TERA txuas ntau npaum li 1.2GHz, uas tshaj qhov kev xa xov kis kab ntawm xya-pawg qauv 600MHz. Muaj plaub qhov yooj yim RJ modular cov thom khwm siv feem ntau ntawm kev sib txuas lus hauv lub network, thiab txhua lub qhov (socket) yooj yim tuaj yeem txuas nrog cov qauv sib txawv ntawm RJ. Piv txwv li, 6 tus pin txuas tau txuas nrog RJ11 (1 khub), RJ14 (2 khub) lossis RJ25C (3 khub); ib lub qhov (8 pin) txuas tau txuas nrog RJ61C (4 khub) thiab RJ48C. 8-core (Keyed) tuaj yeem txuas rau RJ45S, RJ46S thiab RJ47S.
RJ45 qhov (socket) thiab RJ45 txuas (siv lub taub hau siv lead ua) yog qhov yooj yim txuas rau hauv cov kab hlau ua ke. Tus RJ45 txuas muaj lub ntsaws thiab lub qhov (socket). RJ45 module yog ib hom kev txuas rau hauv cov kab hlau txuas, thiab RJ45 qhov txuas, feem ntau hu ua cov taub hau siv lead ua, yog lwm hom. Lub tshuab txuas txuas ntawm ob qhov sib txuas no yog sib txuas ntawm cov xov hlau kom paub cov hluav taws xob txuas ntxiv ntawm cov xov hlau.
