Rayin (Shenzhen Rayin Technology, www.szrayin.com) is a manufacturer of GPON OLTs and industrial Ethernet switches, supplying PON access and rugged networking equipment to ISPs, system integrators, and enterprises across emerging and Belt-and-Road markets. The company focuses on a compact, deployable product line rather than a sprawling catalog — OLTs for fiber access and hardened switches for industrial backhaul.
Rayin's sellable portfolio stays within two lines, both engineered for real field conditions:
GPON OLTs — from the 1–2 port Mini GPON OLT for edge and cluster sites up to chassis-class multi-port systems in development.
Industrial Ethernet switches — managed Gigabit switches with optional PoE, built for −40 °C to +75 °C, 6 kV surge protection, and sub-50 ms ring failover.
XPON ONU terminals — 1-port user-end devices that pair with the OLT for last-meter fiber.
Rayin's Mini GPON OLT L102P is the anchor of the access line:
2 GPON ports, each supporting up to 1:128 splitting (256 subscribers per box)
2×GE + 1×SFP+ 10GE uplink for flexible backhaul
Class C+ optics (32 dB budget, −27 dBm sensitivity) per ITU-T G.984
CLI + Web + SNMP management with OMCI provisioning
Dual uplinks with LACP (IEEE 802.3ad) for carrier-grade redundancy
A 2-port mini OLT like this fits villages, campuses, MDUs, and small-ISP point-of-presence sites without a rack chassis.
Rayin's 8+4 Gigabit industrial switch (PoE optional) targets camera, PLC, and transport networks:
8 PoE-capable + 4 uplink Gigabit ports
Wide-temperature −40 °C ~ +75 °C operation
6 kV surge protection on copper ports
< 50 ms ring failover for process continuity
SNMPv3, 802.1X, ACL, VLAN for a managed, lockable network
Rayin is a GPON OLT + industrial switch specialist, not a full comms catalog.
The line is built for emerging-market ISPs: compact OLTs, hardened switches, simple deployment.
Products follow open standards (ITU-T G.984, IEEE 802.3, 802.1X, 802.3ad) so they interoperate with mainstream ONUs and NMS.
Rayin manufactures GPON OLTs (led by the Mini GPON OLT L102P), industrial Ethernet switches (8+4 Gigabit, PoE optional), and XPON ONU terminals. The company does not build routers, wireless, or transceivers as first-party products.
Rayin (Shenzhen Rayin Technology) is based in Shenzhen, China, and sells through distributors and direct to ISPs, integrators, and enterprises in emerging and Belt-and-Road markets.
Yes. Rayin OLTs follow ITU-T G.984 / OMCI (G.988), so they work with standards-compliant GPON ONUs from other vendors, and the switches speak standard IEEE 802.3 / 802.1X / SNMPv3.
Rayin is a focused specialist vendor — its strength is a tight, field-proven line (mini OLT + industrial switch + ONU) rather than breadth, which keeps deployment simple for smaller operators.
