HUANET EPON OLT 16 Chaw nres nkoj
EPON OLT yog kev sib koom ua ke siab thiab nruab nrab muaj peev xwm cassette EPON OLT tsim los rau cov neeg teb xov tooj nkag mus thiab lub network hauv tsev kawm ntawv.
Nws ua raws li IEEE802.3 ah cov qauv kev siv tshuab thiab ua tau raws li EPON OLT cov kev cai ntawm YD / T 1945-2006 Cov kev cai rau kev nkag mus rau hauv network - raws li Ethernet Passive Optical Network (EPON) thiab Tuam Tshoj telecom EPON kev cai 3.0.
Lub OLT muab 16 qhov chaw nres nkoj downlink 1000M EPON, 4 * GE SFP, 4 * GE COMBO thiab 2 * 10G SFP rau uplink. Qhov siab tsuas yog 1U rau kev teeb tsa yooj yim thiab txuag chaw. Nws siv cov thev naus laus zis siab heev, muab cov kev daws teeb meem EPON zoo. Ntxiv mus, nws txuag tau ntau tus nqi rau cov neeg teb xov tooj vim nws tuaj yeem txhawb nqa ntau yam ONU hybrid networking.
