PLANET EPN-102 - Manual (Page 5)

1. Introduction
With growing network services such as HDTV, IPTV, voice-over-IP (VoIP) and Multimedia
broadband applications, the demand of broadband grows quickly. The present Broadband
environment has not already accorded with needing. Passive Optical Network (PON) is the
most promising NGN (Next Generation Networking) technology. As compared to other
broadband access technologies such as xDSL and cable modem, Passive Optical Network
(PON) technology offers some competing advantages, including a long-term life expectancy
of the fiber infrastructure, lower operating costs through the reduction of “active”
components, support up to 20km distance between equipment nodes, and most importantly,
provide much greater bandwidth.
PLANET EPN-102 / EPN-104 are the GEPON SFU ONU devices. The EPN-102 designed
with one GEPON port, one standard 10Base-T/100Base-TX, one standard 10Base-T /
100Base-TX / 1000Base-TX Ethernet ports, and the EPN-104 designed with one GEPON
port, four standard 10Base-T/100Base-TX Ethernet ports for subscriber access. As
residential device of users or access device of users, it offers economical connection system
of GEPON users, and high broadband service by connected to gateway or PC. Well
satisfying the high speed access demand, GEPON has a more prosperous perspective.
PLANET EPN-102 / EPN-104 provide the core functionality of an 802.3ah Ethernet Passive
Optical Network (EPON) Optical Network Unit (ONU) solution. In addition, the device also
offers some advanced functions such as QoS for Triple-play service, VLAN, Authentication
and Encryption for Security. Users can choose different devices that fit the applications for
residence, SOHO and SMB environment.
