Ethernet Passive Optical Networks (EPON)
Based on the Ethernet standard 802.3, EPON 802.3ah specifies a
similar passive optical network with a range up to 20 km. EPON uses
WDM with the same optical frequencies as GPON and TDMA. The raw
line data rate is 1.25 Gbits/s in both the upstream and downstream
directions.
EPON 24 ports GEPON ONU
EPON 24 ports GEPON ONU technology provides bidirectional 1Gb/s
links using 1490nm wavelength for downstream and 1310nm wavelength
for upstream, with 1550nm wavelength reserved for future extensions
or additional services. EPON is fully compatible with other
Ethernet standards, so no encapsulation or conversion is necessary
when connecting to Ethernet-based networks on either end. The same
Ethernet frame is used with a payload for up to 1518 bytes. As
Ethernet is the primary networking technology utilized in local
area networks (LAN) and now in metro area networks (MAN), no
protocol conversion is needed.
The functions 24 ports GEPON ONU support :
1. Using point to multi point network topology,effectively collect
dispersed user ethernet business then converged in the metropolitan
area network node.Provide standard RJ45 Fast Ethernet interface on
user side,achieve smooth interconnection with existing networks .
2. Dynamic bandwidth allocation(DBA) enables all users to share
1Gbps bandwidth more reasonably,achieve a reliable quality of
service guarantee (QoS).
3. Support IGMP multicast and make full use of broadband.
4. Support port isolation.
5. Support ethernet loop detection,automatically identifies whether
exit ethernet loop block,when the loop disappears, it will
automatically recover.
6. Support VLAN multicast.
7. Support 2-7 layer ACL filtering.
8. Support remote loopback, remote diagnostics network status.
9. OAM design,includes configuration, alarm, performance
monitoring, fault isolation and security management ,provides both
remote administration through OLT and local console management.
10. industrial application.
Product Overview
NTW-E172400H series is a MDU device designed by NATYWISH,integrated Ethernet
switch and optical network unit ONU function,can combine well with
OLT to built an efficient EPON solution,well satisfies the
application of broadcast and television bidirectional network and
FTTO/FTTB.Completely meet the standard of IEEE802.3ah and YD/T
1475-2006.
Product Advantage
NTW-E17800H is an optical network device that meets current market
requirement.
1. One MDU supports 24 ethernet ports(RJ45 port) and one EPON port.
2. EPON: Meet IEEE802.3ah and YD/T 1475-2006 stand .
3. System capacity: 24 ethernet RJ45 ports, achieve ONU and
ethernet switch mixing together in the EPON+LAN access solution.
4. Size :1U, occupies less space in the computer room, consumes
less power and reduces the operating cost of the business.
