GESTAG Installation

Installation Process

GESTAG installation is simple and can be carried out by specialized technicians. The process involves:

Site Analysis: Evaluation of the building’s or home’s hydraulic infrastructure
Planning: Definition of sensor installation points
Sensor Installation: Connection to pulse-output meters
System Setup: 3G network configuration and parameters
Testing: Verification of operation and data transmission
Training: Guidance on how to use the system

Installation Requirements

Pulse-output Water Meters

You need water meters with pulse output to connect to GESTAG.

3G Coverage

The site must have 3G network coverage to transmit data.

Electrical Access

A power point close to the installation points.

Installation Types

Installation in Condominiums

For condominiums, GESTAG can be installed in different ways:

Series Connection: Connects all meters in a single line
Individual Connection: Each apartment has its own sensor
Per-floor Connection: Grouping by building floors

Fiber backhaul for GESTAG

Goal: ensure reliable backhaul between GestAg modules on each floor and the concentrator (router or core switch) using fiber optics — maintaining continuous telemetry, low latency, and an isolated IoT network with security.

Architecture scenarios

1) Ethernet-over-Fiber with Media Converters (simple and modular)

How it works: each GestAg (RJ45 port) connects to an RJ45⇄SFP media converter on the floor; fiber runs up/down to the core switch with SFP/SFP+ slots.

Topology: star (recommended) or ring for redundancy.
Speed: 1 GbE (SFP) or 10 GbE (SFP+), as needed.
When to use: few points per floor, retrofit with narrow conduits, distances up to ~10 km on SM.
Pros: simple, modular architecture compatible with any Ethernet GestAg.
Cons: each converter requires local power, since PoE does not run over fiber.

2) Edge optical switches with SFP slots (centralized management)

How it works: install an L2 switch on each floor with RJ45 ports and 1–2 SFPs. GestAg units connect over copper, and the switch uplink goes over fiber to the core.

Features: VLAN 802.1Q, STP/RSTP, ERPS (G.8032), QoS, port mirroring and SNMP.
When to use: many GestAg units per floor, need to segment traffic (IoT VLAN, voice, data).
Pros: better manageability and consolidation, fewer standalone converters.
Cons: higher cost and complexity; ideal to have UPS on each floor.

3) PON (GPON / XGS-PON) (high point concentration)

How it works: an OLT in the MDF feeds optical splitters in the shaft; on each floor, an ONU delivers RJ45 to local GestAg units.

Capacity: GPON ~2.5/1.25 Gbps; XGS-PON 10/10 Gbps, shared bandwidth.
When to use: tall buildings with many points and few available conduits.
Pros: excellent capillarity and fewer cables back to the OLT.
Cons: requires PON engineering (optical budget) and local power for ONUs.

Components and specifications

Cables and fibers

Single-mode fiber (SM G.652D / G.657A1/A2): building standard, long reach and good bend performance.
Multimode fiber (OM3/OM4): only for short runs (≤ 300 m at 10 Gbps); in buildings, prioritize SM.
LSZH jacket: low-smoke, zero-halogen — ideal for indoor environments.
Indoor/outdoor builds: tight-buffer or breakout options for semi-exposed segments.
Microduct / blown fiber: solution for tight conduits, easing future expansions.

Connectors and terminations

LC/UPC: compact connector, standard in SFPs, excellent for building racks.
SC/APC: widely used in PON, with low optical reflection.
Fusion splicing: preferred method with lowest loss.
Mechanical splices: emergency-only alternative.
ODF / splice enclosures: use one per floor and a dedicated tray in the core rack.

Transceivers (SFP / SFP+)

1G SM SFP 1310 nm: typical 10–20 km links for Ethernet-over-Fiber.
1G BiDi SFP: allows a single fiber per link (different wavelengths for Tx/Rx).
10G SM SFP+: recommended for aggregation or future growth.
PON ONT/ONU: optical modules compatible with GPON/XGS-PON OLT, usually with SC/APC.

Edge equipment

RJ45⇄SFP converters: ideal for Ethernet-over-Fiber scenarios with LFP/Link-Fault-Pass-Through.
L2 switch with SFP: VLAN 802.1Q, STP/RSTP, ERPS (G.8032), QoS and SNMPv3 support.
PON ONU: terminates fiber into RJ45 on each floor and integrates the whole GestAg network.

Power and protection

PoE does not run over fiber: converters, switches and ONUs need local power with UPS.
Grounding: ODFs, racks and shields must be properly grounded.
Physical organization: short patch cords, clear labeling (floor/port/fiber) and bend radius ≥ 10× cable diameter.

Recommended topologies

Star with logical redundancy: one fiber (or BiDi) per floor to the core, with LACP or RSTP for high availability.
Optical ring across floors (ERPS G.8032): L2 switches with SFPs forming a ring and two nodes in the core; typical recovery times < 50 ms.
PON: OLT at the core, splitters in the shaft and ONUs on each floor, with careful optical budget calculation.

L2/L3 layers and security

Dedicated IoT VLAN: isolates GestAg traffic and reduces unnecessary broadcast.
ACLs and firewall: allow only required MQTT/HTTPS/NTP/DNS to the dashboard.
DHCP and IPAM: address control for ONUs, converters and switches.
Monitoring: SNMPv3/syslog for optical levels, flaps and SFP temperature.
L2 redundancy: STP/RSTP or ERPS in a ring, always with controlled configuration.
QoS and NTP: prioritize telemetry and standardize event timestamps.

1× splitter according to fiber plan;
1× SC/APC patch cord;
1× UPS + local power supply.

Deployment in practical steps

Conduit survey: map shafts, trays and available routes.
Choose architecture: Converter, L2 Switch or PON based on power and number of GestAg per floor.
Optical design: choose fiber type (SM G.657), connectors, ODFs and cable slack.
Pulling and splicing: perform splices, OTDR and power measurements (Rx/Tx within budget).
Rack and ODF setup: label ports, fibers and floors clearly.
L2/L3 configuration: IoT VLAN, DHCP, ACLs, SNMP and redundancy protocols.
Commissioning and handover: ping/loss/jitter tests, read SFP levels (dBm) and deliver the “as built”.

Always record initial optical levels to track possible future degradation (bends, dirty connectors, or breaks).
