All-Optical Network Renovation Solution for Manufacturing Industry.AINOPOL Passive Architecture Streamlines Equipment and Cuts Costs by 60%

Nowadays, manufacturing enterprises covering machinery, electronics, new energy, chemical industry and other sectors are accelerating the upgrading of intelligent manufacturing. However, traditional three-layer industrial switch networking has long been plagued by numerous drawbacks including bloated equipment in machine rooms, frequent workshop failures, messy wiring, high power consumption and high cross-plant networking costs, which keep eroding corporate operating profits.

AINOPOL drastically streamlines hardware devices in equipment rooms and floor weak current rooms, achieving an overall cost reduction of 60% in four major aspects: hardware procurement, operation & maintenance manpower, machine room energy consumption and capacity expansion renovation. It supports integrated networking covering workshops, office areas, warehouses and staff dormitories, building a stable, low-cost and easy-to-operate industrial digital infrastructure for factories.

I. Five Core Pain Points of Traditional Industrial Switch Networking Driving Up Long-Term Comprehensive Costs

Most manufacturing plants still adopt three-layer copper-cable networking consisting of core layer, aggregation layer and access layer, together with a large number of industrial switches and PoE transceivers. Combined with harsh workshop conditions featuring high temperature, dust, strong electromagnetic interference and long transmission distance, both explicit and hidden costs keep rising, becoming major obstacles to intelligent manufacturing transformation.

Massive active equipment leads to high hardware procurement costs

A medium-sized manufacturing park with multiple workshops, office buildings and staff dormitories needs dozens of active devices such as core switches, floor aggregation switches, workshop PoE access switches and optical fiber transceivers under traditional solutions. Each device requires separate procurement, matching cabinets and UPS power supply, resulting in huge one-time hardware investment. Moreover, affected by harsh workshop environments, the average service life of switches and transceivers is only 2 to 3 years, requiring batch replacement every few years and bringing continuous hardware renewal expenses.

Frequent equipment failures under harsh working conditions cause immeasurable production halt losses

Machine tools and motors in production workshops generate strong electromagnetic interference. The ambient temperature can exceed 40℃ in summer, accompanied by dense metal dust and oil mist. Ordinary industrial switches are prone to port burnout, mainboard overheating crash and loose network port connection. Once floor aggregation switches break down, PLC systems, visual inspection devices and AGV robots on the whole production line will lose network connection simultaneously. Each shutdown lasts from half an hour to several hours, bringing direct economic losses including delayed order delivery and raw material scrappage. In addition, maintenance staff need to inspect every device in machine rooms floor by floor for troubleshooting, which takes more than 2 hours for a single fault and causes severe manpower waste.

24-hour operation of multi-layer active equipment leads to huge electricity expenses

All switches and optical fiber transceivers run around the clock, and high-power air conditioners in supporting machine rooms and floor weak current rooms keep working for heat dissipation. For a supporting industrial park with 15 floors, the annual electricity bill solely for network equipment reaches 20,000 to 30,000 RMB. Independent power distribution and air conditioning systems are required for each floor’s weak current rooms. Coupled with line power loss, annual network energy consumption has become a fixed financial burden hard to bear for small and medium-sized factories.

Separate wiring for multiple systems causes crowded cable trays and high construction & renovation costs

Traditional networks adopt separate wiring for production networks, office networks, monitoring systems, program-controlled telephones, access control and broadcasting systems. Thousands of cables are laid horizontally within a single factory area with a total weight up to 3570 kilograms, fully occupying the space of cable trays. Adding new production lines or expanding warehouses involves new slotting and wiring construction with long cycles and high labor costs. During the renovation of old factories, original pipelines cannot be reused, leading to high overall renewal investment.

High costs of cross-provincial networking including leased line fees and long-distance call charges

Group manufacturing enterprises with headquarters and multiple branch factories rely on operator MPLS cross-provincial dedicated lines to build internal networks, with monthly rental fees of several thousand yuan per line. Remote communication between headquarters and workshops mainly depends on mobile phones or traditional landlines, resulting in accumulated long-distance call expenses year by year. Meanwhile, fixed bandwidth of dedicated lines easily causes network congestion during high-definition monitoring data transmission and cross-plant video conferences, lowering collaborative work efficiency.

II. Overall Passive All-Optical Renovation Architecture for Manufacturing Industry by AINOPOL

AINOPOL launches a two-tier flattened POL passive architecture integrating converged OLT gateway, passive optical splitters and industrial POF photoelectric terminals for factories. It completely eliminates all floor aggregation switches and PoE active switches. Only one converged core device is reserved in the central machine room, and all intermediate transmission links adopt power-free passive optical components. A single photoelectric composite cable can carry five major services simultaneously: industrial control, office network, Wi-Fi 6, IP telephony and security monitoring, perfectly adapting to high temperature, strong electromagnetic interference and long-distance transmission scenarios in workshops.

1. Core Machine Room: One Integrated OLT Replaces Dozens of Traditional Devices

Traditional machine rooms need stacked devices including core switches, firewalls, routers, IPPBX voice gateways, AC wireless controllers, traffic cleaning equipment and SD-WAN devices.
