High-density standalone OLT in 1U pizza box format — XGS-PON, XG-PON and GPON triple-mode combo PON for carrier networks, FTTx and enterprise.
U10 packs high-density XGS-PON into a 1U standalone unit — easy to install, easy to commission, and ready for multi-vendor networks.
All 8 PON ports run in XG(S)-PON & GPON combo mode by default (XGS-PON 9.953G/9.953G, XG-PON 9.953G down / 2.488G up), and any port can be switched to single GPON mode — start with GPON to keep initial investment low, then move to 10G as demand grows, without replacing the OLT chassis.
1×GE (RJ45) + 4× 10/25GE (SFP28) + 2× 40/50/100GE (QSFP28) uplinks on a 1,960 Gbps backplane with 566.928 Mpps forwarding — no bottleneck at the aggregation layer.
32K MAC, 4,096 VLANs, QinQ, LACP, QoS, IGMP snooping, DHCP server/relay, static, RIP v1/v2, RIPng and OSPF v2/v3 routing, T-CONT DBA and XGEM / GEM traffic — the full carrier feature stack in a pizza box.
6 kV power and 4 kV interface lightning protection, −20°C to +60°C operating range, 4-fan cooling, and flexible single/dual AC or DC power (AC 100–240 V) — built for central offices and remote sites.
The full front-panel layout — PON, uplinks, management and indicators at a glance.
Three reference topologies — each built from UGrid products that work together end to end.
U10 feeds 1:256-split PON trees to UGrid XGS-PON or GPON ONTs. Combo ports let you mix both on the same chassis during migration.
U10 aggregates FiberTrix GPON PoE switches — fiber to the floor, PoE to APs and cameras, all managed from one OLT.
Pair with the uFT intelligent fiber testing system — real-time OTDR fault detection plus AI degradation forecasting on the same outside plant.

The U10 is standards-based — ITU-T G.9807.1 (XGS-PON), G.987 (XG-PON) and G.984.x (GPON) — and interworks with ONUs from multiple vendors.
Everything engineers and procurement need — one click away.
Choosing between XGS-PON and GPON comes down to bandwidth and reuse.

The U10 packs high-density XGS-PON into a 1U standalone unit: 8 combo PON ports serving up to 2,048 ONUs, with 9.953 Gbps symmetric XGS-PON line rate — carrier-grade PON without a chassis system.
Yes. PON ports 1–8 run in combo mode by default, and any port can be switched manually to single GPON mode, so GPON and XGS-PON ONTs can be mixed on the same chassis during migration.
The U10 is standards-based — ITU-T G.9807.1 (XGS-PON), G.987 (XG-PON) and G.984.x (GPON) — and interworks with ONUs from multiple vendors. UGrid's UNT SFP type XGS-PON ONT and UNT SFP type GPON ONT are verified with it.
1 × GE (RJ45), 4 × 10/25GE (SFP28) and 2 × QSFP28 ports (40GE / 50GE / 100GE), on a 1,960 Gbps backplane.
U10 pairs with UGrid ONTs, switches and fiber monitoring for an end-to-end solution.
