Likou tsa HUANET EPON OLT 16
EPON OLT ke khasete e nang le kopanyo e phahameng le bokgoni bo mahareng ya EPON OLT e etseditsweng phihlello ya basebedisi le netweke ya khamphase ya kgwebo.
E latela maemo a tekheniki a IEEE802.3 ah mme e fihlela ditlhoko tsa disebediswa tsa EPON OLT tsa YD/T 1945-2006 Ditlhoko tsa tekheniki bakeng sa netweke ya phihlello——e itshetlehile hodima Ethernet Passive Optical Network (EPON) le ditlhoko tsa tekheniki tsa EPON tsa 3.0 tsa puisano ya China.
OLT e fana ka likou tse 16 tsa downlink 1000M EPON, kou ea 4 * GE SFP, kou ea 4 * GE COMBO le 2 * 10G SFP bakeng sa uplink. Bolelele ke 1U feela bakeng sa ho kenya habonolo le ho boloka sebaka.
