A family of compact GPON OLTs in a variety of port configurations — 1, 4, 8 and 16 GPON ports with 1:128 splitting and 10GE uplinks, from a desktop single-port unit to a 16-port Layer 3 platform.
One GPON platform family for sparse rural rollouts, MDUs, commercial buildings and mobile-site fiber — pick the port count that fits, keep the same management and ONT ecosystem.
1, 4, 8 or 16 GPON ports, each with 1:128 splitting and up to 20 km reach — right-size the OLT to the service area instead of over-buying chassis capacity.
Every U5 pairs GE RJ45 with SFP(GE)/SFP+(10GE) optical uplinks, so even the desktop U5-1 backhauls at 10G.
4,096 VLANs with QinQ and VLAN translation, IGMP snooping, port isolation, port rate limiting and storm control across the range.
The 1U models route at Layer 3 — static, RIP v1/v2, RIPng and OSPF v2/v3 with 4,096 hardware host routes; the desktop U5-1 adds static routing with NAT, DMZ and WAN access (DHCP / PPPoE / static IP).
ONT auto-discovery, link detection and remote software upgrade, with online ONT configuration and management from CLI, Web, SNMP or Telnet.
Desktop U5-1 on AC or a 12 V DC adapter; 1U models with 1× AC, 2× AC, 2× DC or 1× AC + 1× DC power configurations for equipment rooms, basements and shared wireless sites.
The U5-8 front panel — GPON ports, uplinks, management and indicators at a glance. The other 1U models follow the same layout.
Every model ships with its own datasheet (R01). Quotes are handled per model — the quote form's Port Number field carries your selection.

The U5 is standards-based (ITU-T G.984.x) and interworks with ONUs from multiple vendors.
Contact us for the current ONT interoperability list for your deployment.
The U5 reference architecture pairs the OLT with a UGS3 Series aggregation switch on 10GE and UNT series ONTs at the subscriber — one vendor for the full access chain, with standards-based GPON keeping the ONT layer open.
GPON ONTs serve subscribers with GE, POTS and Wi-Fi at the premises.
U5 is the cost-optimized GPON family; U10 adds XG(S)-PON combo ports for 10G PON migration and coexistence on the same fiber.
