Point-to-point optical Ethernet

A defined starting point for technical review.

This is an illustrative reference design, not a completed installation or a final site quotation. Quantities and capacities follow the assumptions below.

Scale & assumptions

One office block, one warehouse and four production/security zones. Existing machine-control networks remain outside this reference supply boundary.
Four IEF4320 industrial nodes each serve two cameras, one AP and three non-PoE telemetry gateway connections; two spare copper ports per node.
An illustrative 400m longest optical run, local 52–57V DC available in each industrial enclosure and protected indoor AP locations.
Two additional office APs and up to 20 office/phone connections on one PoE switch. RF coverage, EMI, surge conditions and actual cabinet temperature must be surveyed.

Why this architecture

IEF4520 aggregation and IEF4320-PWR industrial access are selected by their documented port, temperature and supply characteristics. Four GE optical combo ports on IEF4520 serve the four GE industrial links; their copper combo mates are not extra usable ports.

When to choose another approach

A standard office Ethernet or PON room network can serve clean offices and dormitories. It does not automatically meet production cabinet, vibration, temperature, timing or hazardous-area requirements. Redundant industrial rings require an approved protocol, port map and failure test.

Compare the three architecture families →

Office IT

Business applications, two WLAN APs and up to 20 user/phone ports.

Service boundary: Staff/guest/voice policies; no unrestricted office-to-machine route.

Production telemetry

Read-only collection through approved telemetry gateways.

Service boundary: PLC, safety and deterministic control networks retain their validated architecture. Gateway allow-lists require plant approval.

Warehouse & security

Four sample APs for mobility and eight camera streams.

Service boundary: RF roaming through metal racks, scanner clients and CCTV storage are separate design checks.

New construction

Provide industrial enclosures, earthing, environmental clearance, local DC supplies and fiber routes before line installation. Allocate cable paths away from power drives according to the plant's installation requirements.

Upgrade / retrofit

Inventory each machine/OT boundary with the plant team, preserve working control links and add telemetry through approved gateways. Pilot an off-line or noncritical zone before moving warehouse/security traffic.

Logical services & boundaries

Keep office IT, guest WLAN, warehouse clients, CCTV, management and production telemetry in separate service zones. An approved industrial firewall/DMZ is required where traffic crosses the OT boundary; this reference does not replace a control/safety network design.

Electrical power path

Each industrial node uses rated local 52–57V DC. Its maximum total PoE output is 60W, despite eight 30W-capable ports. IEF4520's 370W remote output is unused in this baseline. UPS/DC backup, earthing and surge protection follow the actual plant conditions.

Link schedule — interfaces, bandwidth and components

Link / endpoints	Speed / sharing	Physical path & interfaces	Modules / configuration conditions
L1 WAN-01 → FW-01	1GE Dedicated link / channels	Reference 1GE ISP handoff. Actual contracted bandwidth may be lower.	Carrier CPE and copper patch lead; change optics/ports if the actual handoff differs.
L2 FW-01 → CORE-01	1GE Dedicated link / channels	Dedicated GE connection to the core. Review WAN demand before retaining this reference speed.	Cat6 patch lead. The 1GE boundary is an explicit capacity limit.
L3 CORE-01 → IAGG-01	10GE Dedicated link / channels	Core SFP+ to industrial aggregation SFP+.	2 supported 10G optics and OS2 pair with appropriate temperature rating.
L4 IAGG-01 → IACC-01–04	4 × 1GE Dedicated link / channels	Four dedicated GE links using IEF4520 GE optical combo ports; exclude their copper mates.	4 compatible GE optical pairs, industrial-temperature variants as required; local power independent.
L5 IACC-01–04 → IAP-01–04	1GE Dedicated link / channels	One af-powered AP per industrial switch; survey roaming and interference.	4 protected copper channels and mounting accessories.
L6 IACC-01–04 → OT-01–04	1GE Dedicated link / channels	Five links per zone: 3 telemetry gateways + 2 cameras. Telemetry and surveillance separated by policy.	20 copper channels; approved gateways and camera models selected separately.
L7 CORE-01 → OACC-01	1GE Dedicated link / channels	Core GE combo optical port to office GE SFP. Reserve its copper combo mate.	One compatible GE optical pair and labeled fiber route.
L8 OACC-01 → OAP-01–02	1GE Dedicated link / channels	Two office AP connections; user outlets occupy separate access ports.	Cat6 channels; office endpoint schedule confirmed by drawings.
L9 CORE-01 → SRV-01	10GE Dedicated link / channels	Approved IT-side application/recording service uplink.	Matched 10G pair/DAC and service NIC; no implicit bridge to control networks.

Declared inputs · reviewable calculations

Capacity and power, with their limits visible.

Planning allocations are assumptions, not measurements of unselected endpoints. Reconcile them with the final device classes, configuration and site tests.

Industrial ports

4 × 8 = 32 copper ports; 4 × 6 = 24 assigned; 8 spare.

One GE fiber uplink per node is dedicated. Test burst traffic from telemetry, cameras and scanners against that GE uplink.

Industrial PoE

Per node: 1 AP at 16W + 2 cameras at 15W = 46W. With 20% planning reserve: 55.2W.

Below 60W, subject to actual PSE allocation and startup load. Adding one more 15W camera would exceed the budget with this reserve.

Office power

2 APs at 16W + an assumed 10 phones at 8W =112W; 20% reserve gives 134.4W.

Below 370W. Actual user/phone point count and endpoint models still need a port schedule.

Video traffic

8 cameras at assumed 8Mb/s =64Mb/s before overhead/playback.

Size VMS ingestion, retention and storage separately; industrial switching does not determine recorder channel limits.
