Broadband Passive Optical Network
ZyXEL’s OLT-1308S-22 GEPON system (Optical Line Termination, OLT) is located in the operator’s
central office and different types of ONU (Optical Network Unit, ONU) are located at customer
premises for FTTB/H connections. The OLT-1308S-22 is connected by a single fiber to an optical
power splitter that supplies the optical signal to as many as 256 sets of ONUs (each OLT PON port
supports up to 32 ONU sets). The OLT-1308S-22 is a mini chassis with a Layer-2 GEPON switch
featuring 8 GEPON ports (including 3 PON modules), 4 Gigabit uplink ports (2 copper and 2 combo
ports) and one 10/100 Mbps Ethernet port for out-of-band management. For CPE compatibility,
ZyXEL provides several models for different network architecture needs.
High Bandwidth
As demand for broadband services such as high-definition TV (HDTV), media-on-demand (MoD),
voice over IP (VoIP) and online gaming increases continuously, GEPON technology emerges to
provide astounding 1.25 Gbps bandwidth for both upstream and downstream, giving a 30 Mbps
bi-directional bandwidth to up to 32 subscribers each. It is a cost-effective access technology with a
reliable and scalable carrier-grade Ethernet infrastructure that really addresses Triply-play service
needs.
Cost-Effective Operations beyond Initial Fiber Deployment
Construction of the fiber access network is the most labor-intensive task in FTTX projects and thus
the most expensive. However, PON architecture requires less cost since it requires less fiber. PON
networks use splitters to allow minimal fiber deployment in local loops. In addition, it requires no
power between CO and network’s termination that lead to lower maintenance costs.
20 km Long Distance Coverage
On a PON network, subscribers must be within 10 to 20 km from the CO, depending on the total
number of splits (distance decreases as splits increase). The OLT-1308S-22 supports a maximum
distance of up to 20 km, and users can choose the different distances ONU type for 10 km or 20 km
deployment to adapt to the existing network structure.
High Scalability and Flexibility for Easy Installation and Maintenance
Since ONU can be added to or removed from the network architecture easily and economically,
its great flexibility is perfect for the deployment of different network architectures. FTTH deploys
ONU in residences, while FTTN/FTTC is the combination of fiber and existing copper infrastructure.
In addition, administrators can upgrade firmware, test loopbacks and detect failures remotely.
