Broadband passive optical network

ZyXEL’s OLT-1308S-22 GEPON system (Optical Line Terminal with 4-port GbE Switch) is located in the operator’s central office, while different types of Optical Network Units (ONU) are located at customer premises for FTTB/FTTH 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 512 sets of ONUs (each OLT PON port supports up to 64 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.

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 lowered maintenance costs.

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 1.25Gbps bandwidth for both upstream and downstream, giving a 30Mbps 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.

20 km long distance coverage

On a PON network, subscribers must be within 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 20 km deployment to adapt to the existing network structure.
