GPON OLT & FTTH Access – APX-OLT-GPON-5U
Product Overview
The Apex APX-OLT-GPON-5U is a 5U modular GPON OLT for access sites that need redundancy and room to grow without the footprint of a 10U central-office chassis.
PON and uplink capacity scales card by card as subscribers grow. Each PON port supports up to 128 GPON ONUs with five bandwidth templates (T-CONT) and dynamic bandwidth allocation, and ONUs can be authenticated by LOID, serial number, password or a combination. Ranging and logical-distance configuration are handled per PON port.
The platform complies with ITU-T G.984 and G.988 and with common operator access standards, and adds Type-B PON protection plus 1+1 control and power redundancy for continuous service during card or link failures.

Available Configurations
APX-OLT-GPON-5U Modular Chassis
The 5U chassis sits between the fixed 1U 16-port model and the 10U high-density chassis. PON and uplink cards are added as subscriber demand grows, and Type-B PON protection together with 1+1 control and power redundancy keeps services running through card or link failures.
Applications
Fiber-to-the-Home Broadband
Terminates GPON access lines and delivers residential triple-play services with dynamic bandwidth allocation and per-ONU service control.
Enterprise and Campus PON
Delivers high-capacity fiber access to businesses, campuses and multi-dwelling units, with VLAN isolation and QinQ for clean service separation.
Mobile and FTTx Backhaul
Aggregates GPON access toward metro transport, supporting mobile small-cell and fixed-mobile convergence deployments.
Compatibility
Interoperable with major optical transport and networking platforms. Standard GPON interfaces and ITU-T G.984/G.988 compliance let these OLT platforms serve GPON ONUs and connect to existing metro transport networks.
Frequently Asked Questions
How many ONUs does each PON port support on the 5U model?
Up to 128 GPON ONUs, shared through five bandwidth templates (T-CONT) with dynamic bandwidth allocation.
Does the 5U model offer PON protection?
Yes. It provides Type-B PON protection plus 1+1 redundancy on the control and power cards.
What ONU authentication methods are supported?
LOID, serial number, password or combined authentication, along with batch ONU upgrade and capability-set queries.
How does it differ from the 10U chassis?
The 5U chassis serves access sites that need redundancy and growth room in less rack space, while the 10U model delivers the highest PON and uplink density for large central offices.
Which standard does the platform follow?
ITU-T G.984 and G.988, along with common operator access standards.
