Standalone GPON OLT (ISCOM5508-GP) GPON

SCOM5508-GP is a compact GPON OLT with enhanced functionality that can support up to 8 GPON, 10 GE and 2 x 10GE interfaces. It's compliant with ITU-T G.984


The ISCOM5508-GP is a compact GPON OLT with enhanced functionality that complies with the GPON’s ITU-T G.984 standard. The device can support up to 8 GPON, 10 GE and 2 x 10GE interfaces. The complete modular design of the ISCOM5508-GP enables excessive flexibility in deploying, maintaining and expanding services at reduced CAPEX and TCO. Designed for large enterprises, SME and residential fiber access, the ISCOM5508-GP offers a broad range of features delivering triple-play services, simplifying management, and providing high network reliability. Security is assured by implementations of RADIUS and/or TACACS+, while maximum network uptime is guaranteed by a ring protection mechanism, real-time monitoring and hot-swappable redundant power supplies. In parallel, the ISCOM5508-GP device supports multi-purpose access and aggregation PON and xDSL DSLAM Ethernet traffic.
