GPON OLT & FTTH Access – APX-OLT-GPON-10U
Product Overview
The Apex APX-OLT-GPON-10U is the largest chassis in the GPON OLT family, a 10U modular platform for busy central offices that need high PON port density and full redundancy.
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-10U Modular Chassis
The 10U chassis holds the largest number of PON and uplink cards in the family, aimed at high-density central offices. 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 10U model?
Up to 128 GPON ONUs, shared through five bandwidth templates (T-CONT) with dynamic bandwidth allocation.
Does the 10U 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.
Can capacity be added after installation?
Yes. PON and uplink capacity scales card by card, so the chassis grows with the subscriber base.
Which standard does the platform follow?
ITU-T G.984 and G.988, along with common operator access standards.
