Tellabs offers XGS-PON/GPON FlexSym OLT1 for passive optical LANs
Tellabs has unveiled the FlexSym OLT1, a 1RU optical line terminal (OLT) that will support both 10-Gbps XGS-PON and GPON for passive optical LAN (POL) applications. The system is in the limited availability stage ahead of customer trials, according to the company.
Tellabs says the ability to support XGS-PON has become increasingly important as the demands on enterprise and smart building networks increase. For example, the OLT is optimized to support 802.11ax WiFi6, the company explains. However, the ability to support GPON enables network managers who don’t need 10G capacity now to meet their current needs with a migration to greater capacity in the future.
Salient features of the FlexSym OLT1 include:
- AC powering for the 1RU/19-inch system with redundant power supplies.
- An eight-port PON service module that enables selection of XGS-PON or GPON by swapping pluggable XFP optics
- Support of up to 512 optical network terminals (ONTs; via a 64-way optical split) and up to 4096 Ethernet ports (via ONT248)
- Four ports of Gigabit Ethernet and two ports of 10 Gigabit Ethernet network uplink interfaces
- Security via bi-directional AES128 encryption with churning keys
- Software-defined network management capabilities
- Environmental hardening to support a variety of mounting options.
“When we say the OLT1 maximizes network speed, we are speaking about three distinct areas of improvement. First, the increase in 10G-PON transport capacity between OLT and ONT; and second, the ability to backhaul the faster multi-rate Ethernet 1G, 2.5G, 5G, and 10G end-points; and third, we are talking about the ability to support a greater number of Ethernet end-points,” said Rich Schroder, Tellabs president and CEO. “These three capacity improvements are imperative gains in order to satisfy the increasing future demands of our customers’ IoT, wireless, cloud, and smart buildings requirements.”
