FTTR-Planner

GPON System Design Tool

About

Plan a fiber-to-the-room (FTTR/GPON) network for your hotel or resort — from first inputs to a quote-ready bill of materials, in under a minute.

How it works

Walk through five steps. Each focuses on one part of the planning process; you can jump between them from the sidebar at any time.

  1. Parameters — enter project name, number of endpoints, longest fiber distance, bandwidth per endpoint, and optional services (WiFi, CATV, PoE, IPTV).
  2. System Design — the planner picks OLT, splitter cascade and endpoint model; you see the bandwidth estimation gauge and the full optical power budget (incl. RF overlay when CATV is selected).
  3. Topology — top-down schematic of the system (ISP, OLT, splitters, endpoints, RF / IPTV path when active).
  4. BOM — printable bill of materials ready to hand off to procurement.
  5. Quote — mailto-based request form that ships the configuration summary to AXING support.

Methodology

Bandwidth estimation

Hotel-industry formula per HTNG and Broadband Forum TR-126. The per-endpoint demand is multiplied by:

  • 50 % endpoint concurrency — not all rooms active simultaneously
  • 80 % room occupancy
  • 5 Mbps per active user (7 Mbps when IPTV is selected)
  • WiFi factor 1.25× when in-room WiFi is selected
  • 20 % headroom

Optical power budget

Per-link loss computed from catalog values:

  • Fiber attenuation 0.4 dB/km @ 1310 nm (OVK spec)
  • Connector loss 0.3 dB each (OLT, every splitter stage, endpoint)
  • Splitter insertion loss per datasheet
  • WDM insertion 1.0 dB (OMX 1514-04) when RF overlay is active

Each device's optical class (per ITU-T G.984.2) sets its Tx power range and Rx sensitivity window. When OLT and ONU belong to different classes, the effective budget is bounded by the weaker end of the link.

ClassOLT TxONU Rx sensMax path loss
A−3…+2 dBm−23 dBm20 dB
B−2…+3 dBm−26 dBm25 dB
B++1.5…+5 dBm−27/−28 dBm28 dB
C++3…+7 dBm−30 dBm32 dB
C+++4.5…+10 dBm−31 dBm35+ dB

The current AXING catalog uses Class C++ OLTs and Class B+ ONUs (highlighted row above). The asymmetric link is bounded by the weaker B+ end, giving an effective downstream budget of 32.5 dB. RF overlay at 1550 nm reuses the same shared-plant loss and adds the 1:N RF source split between OTX/EDFA and the OMX channels.

Hardware selection

Exactly one OLT per system (catalog constraint — 1× OLTH 4-01 max). Splitter cascade picked automatically: single-stage 1:N up to 64 endpoints per port; two-stage 1:2 + 1:N beyond. Endpoint chosen by feature flags (PoE → OSE 44-01, CATV → OEP 43-01, WiFi or multi-port → OEP 41-01, default → OEP 11-01).

Scope & assumptions
General
Preliminary system design from simplified assumptions. Always validate against detailed requirements and site conditions before ordering.
Splitters
The planner picks the lowest-loss ratio for the computed endpoints-per-port (cascaded 1:2 + 1:N when no single stage fits). Real deployments often use per-floor or per-riser splitter locations that are not modelled here.
Endpoints
Selected by port count and feature flags. AXING publishes no WiFi-integrated endpoint — when WiFi is selected, an external access point per endpoint is assumed (not listed in the BOM). Wireless coverage, capacity and PoE power budget are not modelled. The PoE + CATV combination is not supported by any single endpoint.
Bandwidth
Codec, resolution and channel mix for IPTV are out of scope. The streamer listed in the BOM is the MK 16-06H as a baseline — it outputs RF and IPTV simultaneously, so a single headend covers both overlays. For IPTV-only deployments the MIP 16-06 (or another model from the MIP range) is an alternative. Scale to your actual channel count; full AXING DVB headend range.
Optical budget
Loss computed from catalog values only. Splice losses, connector degradation and wavelength drift are not included — keep a safety margin.
Redundancy
Single-headend design (1× OLT, one WDM, one streamer). No dual uplink, redundant OLT, UPS or backup path. Add explicitly for production deployments.

Project ID

System Requirements

One endpoint per room or unit — a multi-port endpoint can serve a suite or several devices from one box. 1–512. Above 128: contact AXING for detailed planning.
m
Longest OLT-to-endpoint run. Up to 100 m each endpoint gets a pre-terminated drop rounded up to the next catalog length; beyond that the BOM lists a placeholder asking AXING for a cut-to-length cable spec (splicing required on site). 1–500 m.
Mbps
Target downstream capacity per endpoint. The planner picks a GPON split so each endpoint sustains this rate at 50 % concurrency. 10–250 Mbps.
Wired Ethernet devices per unit — e.g. IPTV STB, WiFi access point, desk phone, or smart TV. Feeds endpoint selection and bandwidth estimation. 1–4.
