Unifi Business vs Maxis Dedicated Fiber for Plants

Contended GPON vs Dedicated Leased Line

Unifi Business is a retail SMB product that lives on Telekom Malaysia’s FTTH/GPON access layer. The fiber from your plant’s equipment room terminates into an OLT with a split ratio that in Malaysia’s Klang Valley typically runs 1:32 or 1:64. That means your plant’s backhaul is effectively shared with every residential subscriber feeding off the same PON port. A 500Mbps Unifi Business plan will burst well below that number at 9pm when the condos around Shah Alam’s industrial zone start streaming video. Upload is worse: the top-tier plan gives you 500Mbps down / 75Mbps up, which throttles any sustained uplink stream within minutes.

Maxis Dedicated Fiber is a layer-2 or layer-3 leased line. The handover is on a dedicated physical port at the exchange, with a committed information rate written into the contract. If you buy 100Mbps symmetric, you get 100Mbps up and 100Mbps down at 8am and at 9pm. No splitter contention, no best-effort burst. The entire path from your plant’s router to Maxis’s aggregation core is reserved for your circuit.

Plant Floor Workloads That Break GPON

A food processing plant in Senai or a precision machining shop in Kulim Hi-Tech Park runs software that does not tolerate asymmetric upload or dropped packets:

– SAP S/4HANA and MES replication: Background jobs in SAP, and MES systems like Apriso or Camstar, push continuous delta streams to a head office or a cloud ERP in Singapore. A 75Mbps upload cap becomes a hard ceiling during month-end MIRO runs.

– SCADA / PLC telemetry: Schneider Electric and Siemens S7 controllers are polled by remote engineers through VPN tunnels. Any loss on the contended uplink triggers false alarms and uncontrolled process shutdowns.

– CCTV with cloud analytics: Factories in Malaysia are moving weighbridge plates, gate entry, and line-end OCR (e.g., plate scanning for logistics) to cloud services. Those services need sustained upload of 6–8Mbps per camera. A 32-camera site simply cannot fit through Unifi Business’s upload cap.

– IPSEC failover tunnels: Plants running dual-WAN setups find that a GPON line drops micro-bursts under load, which kills the IPSEC phase-2 security associations. Maxis’s dedicated circuit holds steady jitter under 2ms, which is what FortiGate and MikroTik failover rules assume.

SLA, Repair Windows, and Penalty Clauses

The practical difference for a plant manager is what happens when the line dies at 2am on a production Saturday.

Unifi Business standard plans do not carry a monetary SLA. TM’s restoration commitment is “by next working day,” which in practice means Monday afternoon if the fiber cut occurs on a Friday night. There is no credit formula that pays your lost production time. The residential-grade CPE (Huawei EchoLife ONT) also has no built-in redundant power feed—a brownout in Perak’s industrial estates will take the box down with the grid.

Maxis Dedicated Fiber carries a 99.9% availability SLA with commuted credits typically triggered after four continuous hours of outage. For Klang Valley and major industrial corridors (Shah Alam, Pasir Gudang, Senai, Prai), Maxis’s enterprise NOC commits to a 4-hour on-site repair window. The handover CPE is a business router (often Nokia or Cisco), which can be rack-mounted with redundant power on a UPS or a secondary supply. That is the difference between a nuisance call and a chargeback episode with your customer.

Route Design, IP Blocks, and Security Boundaries

Even if Unifi Business gives you a “static IP,” that address sits behind TM’s shared gateway (AS4788). You cannot apply BGP inbound routing, you cannot control route preference, and the gateway itself belongs to a pool that TM rescans and filters for abuse. If your plant operates public-facing infrastructure—e.g., an EDI file server, a Tesla or IEC 61850 gateway, or an occupied building with tenant-accessible Wi-Fi—you want a clean, portable IP allocation.

Maxis runs its own autonomous system (AS9534) with direct peering into regional IXPs and its own submarine cable ownership (SEA-ME-WE 5 participation). A Maxis dedicated circuit can be delivered with a routed /30 or /29 block, which means you control the edge router, do your own NIDS placement, and segment OT vs IT traffic with proper VLAN tagging at the handoff. Unifi Business only gives you a single dynamic/subscribed static WAN IP on a shared gateway—which forces you to run everything behind NAT unless you push a DMZ hack. That’s a security boundary problem for a plant audit, not a technical luxury.

Choosing Based on Plant Site Profile

Use Unifi Business as the primary line only in a small feeder plant or depot—a site with fewer than 30 staff, local file servers, no full CCTV coverage, and light ERP usage. Even then, budget for it to be the backup circuit on the secondary WAN port of your router, because TM’s coverage in industrial estates is extensive and the RM299/month price point is hard to beat.

Spec Maxis Dedicated Fiber for any site that qualifies as a real production facility: manufacturing floor runs MES software, the weighbridge has a camera, or your customer contract contains a KPI for ERP uptime. Expect to pay RM900–RM1,500 per month for 200Mbps symmetric with a 36-month lock-in, with installation lead time of 30–60 days if Maxis needs to build out from the nearest POP. A plant in Pasir Gudang will justify that cost in one avoided shift of downtime.
