Passive Optical Networking
Tellabs 1131 OLT is compliant with the ITU-T G.984 standard. It supports Ethernet-centric GPON Encapsulation Mode (GEM), multiple T-CONTs and GEM ports per device, both single T-CONT and multiple T-CONTs modes. Tellabs 1131 OLT offers flexible mapping between GEM ports, T-CONT and priority queue-based scheduling. It is secure with activation of an automatically-discovered Serial Number (SN) and password, plus Advanced Encryption Standard (AES) AES-128 encryption with 60-second key generation and switching as well as Tellabs QOIU7 highly reliable Forward Error Correction (FEC). It supports Dynamic Bandwidth Allocation (DBA) and extended optical reach as far as 18.5 miles (30 km), as well as fiber route diversity and geographically dispersed OLTs with Type-B PON redundancy.
Tellabs 1131 OLT comes equipped with four Gigabit Ethernet and two 10-Gigabit Ethernet network uplink interfaces. These 1 GbE and 10 GbE ports are integral to the Ethernet switching fabric, common control and timing mechanism of the Tellabs OLTs. The Tellabs 1131 OLT supports extended optical reach as far as 18.5 miles (30 km).
Tellabs 1131 OLT advanced security is maintained through the regimented support of Network Access Control (NAC), IEEE 802.1x, RADIUS, MAC Authentication Bypass (MAB), Dynamic ARP Inspection (DAI) and DHCP. Additional security functions include Access Control List (ACLs) implemented at Layer-2, Layer-3 and Layer-4 triggers.
