INFORMATION
Brief Views
BD-ONT-311R is fiber to
the home multi service access GPON ONT. It’s based on the mature, stable, high
cost performance GPON technology and has gigabit Ethernet switching, WDM and HFC
technology. BD-ONT-311R has a
higher bandwidth, higher reliability, easy management and good quality of
service (QoS) guarantee with technical performance of equipment meet the ITU G.
984 requirements and have good compatibility with third party manufacturers
OLT.
GPON is the latest generations
of access network technology. ITU-T G.984 is the standard protocol of GPON. The
GPON standard differs from other PON standards in that it achieves higher
bandwidth and higher efficiency using larger, variable-length packets. GPON
offers efficient packaging of user traffic, with frame segmentation allowing
higher quality of service (QOS) for delay-sensitive voice and video
communications traffic. GPON network provides the reliability and performance
expected for business services and provides an attractive way to deliver
residential services. GPON enables fiber to the home (FTTH) deployments
economically resulting to accelerated growth worldwide.
It adopts single fiber WDM
technology with downlink wavelength 1550nm and 1490nm, uplink wavelength 1310nm
. It only needs one-core fiber to transmit data and CATV service.
