EPON-OLT - Optical Line Terminal

The OLT optical line terminal for IEEE802.3ah compliant EPON is part of our next generation FTTx product range.

The OLT and the matching ONU subscriber units enable the deployment of cost effective, low maintenance, next generation EPON systems for business and residential networks, over a passive optical fibre network.

Designed to deliver Gigabit Ethernet over two or four shared bi-directional single mode fibres to up to 128 remote nodes, the OLT includes dynamic bandwidth allocation (DBA) and QoS enforcement for multi-service applications that deliver “Triple Play” communication services.

The wide area network (WAN) interface supports fixed Gigabit Ethernet via two or four RJ-45 twisted pair connectors or duplex multimode fibre ports.

The EPON interface supports two or four angle polished fibre optic connectors for full duplex bi-directional transmission over standard 10 and 20 km or optional 40 km on single mode fibre cores.

There is an option for an integrated optical wavelength division multiplexer (WDM) for a cable television (CATV) overlay transmission at 1550 nm on the same fibre core. This permits delivery of analog cable television with 110 NTSC or 91 PAL channel capacity, as well as DVB-C and DVB-T digital television standards.

Status monitoring data is available on a large LCD readout as well as via a front panel mounted USB craft port. An Ethernet port for SNMP/HTTP network connectivity is available as an option.
