The Rayin Mini GPON OLT L102P is a 2-port GPON OLT that delivers 1:128 splitting per port with 2×GE plus 1×SFP+ 10GE uplink — a compact access device for edge FTTH, campus networks, MDUs, and small-ISP point-of-presence sites where a full chassis OLT is overkill. It follows the ITU-T G.984 GPON standard, so it interoperates with mainstream GPON ONUs.
A chassis OLT is built for thousands of subscribers in a central office. Most real edge sites need far less: a village, a campus, a single building cluster, or a small-ISP PoP. A mini OLT drops the empty slots, the power redundancy, and the footprint — while keeping the same GPON protocol, management, and split ratio. The L102P serves up to 256 subscribers (2 ports × 1:128) from a box that sits on a shelf.
| Parameter | Specification |
|---|---|
| PON ports | 2 × GPON (ITU-T G.984) |
| Split ratio | Up to 1:128 per port (256 ONUs total) |
| Downstream / upstream | 2.488 Gbps / 1.244 Gbps per port |
| Uplink | 2 × GE + 1 × SFP+ 10GE |
| Optical class | Class B+ (28 dB) / Class C+ (32 dB) |
| Receiver sensitivity | −27 dBm (Class C+) |
| Management | CLI + Web + SNMP, OMCI (ITU-T G.988) |
| Reach | Up to 20 km per PON port |
Per ITU-T G.984.2, one GPON port carries 2.488 Gbps down / 1.244 Gbps up. At a realistic busy-hour concurrency of ~6 Mbps per ONU:
1:64 split → ~384 Mbps upstream concurrency per port
1:128 split → ~768 Mbps upstream concurrency per port
Two ports at 1:128 → ~1.5 Gbps summed, covered by one 10GE SFP+ uplink with headroom
The L102P's 10GE SFP+ means you never bottleneck at the uplink even when both ports run 1:128. For the full planning method, see our GPON uplink planning guide.
2 GPON ports × 1:128 = 256 subscribers from one compact box.
2×GE + 1×SFP+ 10GE uplink removes the classic mini-OLT bottleneck.
OMCI + SNMP management and LACP dual uplink make it carrier-grade at the edge.
Up to 256 (2 PON ports × 1:128 split). Realistic concurrent users depend on uplink bandwidth and busy-hour per-ONU rate, not just the split number.
Not always. At 1:64 per port, two GE links suffice. At 1:128 or higher concurrency, the 10GE SFP+ becomes necessary — having it built in means you never swap the box as you grow.
Yes, if they are standards-compliant GPON ONUs (ITU-T G.984 / OMCI G.988). Rayin OLTs interoperate with mainstream third-party GPON ONUs and XPON ONU terminals.
Via CLI for bulk config, Web for visual status, and SNMP to feed a central NMS. OMCI handles per-ONU provisioning, and SNMP traps surface optical-fault and registration events.
Yes — the L102P supports dual uplinks with LACP (IEEE 802.3ad), so a single link or path failure causes no service loss.
