FTTO or FTTH for SMEs: choosing fibre

Choosing between FTTO and FTTH for an SME in PACA is not a matter of comparing two speeds on an operator sheet. On the Côte d'Azur and in Monaco, dedicated fiber (FTTO) and shared fiber (FTTH) do not offer the same GTR, the same bandwidth sharing, or the same cost. Host Technology, an integrator in Tourrettes-sur-Loup, helps decide according to real use: IP telephony, multi-site, overnight backup, seasonal peaks.

SME FTTH: shared, quick to deploy

Business FTTH shares the last mile with other subscribers. Advertised throughput is symmetric or asymmetric depending on the offer, connection lead time is often shorter, and the price is lower. The limit: you share the node’s capacity. On a rush day or after a collective outage, the GTR (guaranteed time to restore) often remains long, or absent on entry-level offers. For an office of 10–30 workstations with voice QoS properly set, FTTH is frequently enough.

Host Technology also compares total cost: works, lead time, GTR, 4G backup, and the impact on telephony and backup. The monthly price alone often misleads.

Dedicated FTTO fiber: commitment and isolation

FTTO runs a dedicated fiber to your premises. Guaranteed throughput, a written SLA, a GTR typically of 4 hours or less depending on the contract. Higher cost, longer works lead time (cable route, permissions, technical room). For a hotel, a clinic, or a headquarters that cannot stay without voice or VPN, dedicated fiber becomes the foundation, not a luxury. Host Technology visits before promising a date.

On FTTO, require clarity on the demarcation point and patching responsibilities. Many disputes start from a badly placed ONT or a room that is not ready.

GTR and SLA: read the contract, not the marketing

A 4-hour GTR does not mean “everything works in 4 hours.” It covers the operator link, not your misconfigured firewall or your failed switch. Host clarifies the boundary: operator responsibility versus LAN responsibility. Contacts, incident numbers, and the plan B (4G/5G backup) are documented. Without that, the SLA remains a paper promise.

Host monitoring opens the operator ticket with the right measurements (traceroute, loss, timestamp) so the GTR starts without sterile dispute.

Impact on IP telephony

VoIP requires stable latency and jitter. FTTH saturated in hotel peak season degrades reception even with a voice VLAN. FTTO absorbs peaks better, especially if several sites synchronize calls and VPN. Host aligns the fiber choice and SIP trunk sizing: channels and throughput rise together.

A hotel in peak season on FTTH must absolutely combine voice QoS, guest throttling, and cellular backup. Otherwise the switchboard pays for streaming in the rooms.

Cloud backup and overnight windows

A 3-2-1 backup to the cloud consumes bandwidth. On asymmetric FTTH, the overnight window can spill into the morning and disturb telephony. On guaranteed symmetric FTTO, planning is more predictable. The integrator calculates volume, retention, and throughput before the fiber offer is signed.

Measure real throughput at backup hours: that is often where FTTH shows its limits for an ambitious 3-2-1 policy.

When FTTH is enough (and when it is not)

• FTTH suited: office of 10–30 workstations, IP telephony with QoS, predictable load, tight budget.
• FTTO preferred: critical sites, dense VoIP, synchronized multi-site, a continuity obligation, short GTR.
• Hybrid is common: primary FTTH plus tested 4G/5G backup, or FTTO at headquarters plus FTTH at branches.
• Seasonal hospitality in PACA: size for the peak, not the low season.
• Monaco / constrained buildings: anticipate the cable route and FTTO lead times.

The checklist is completed by a visit report and a 36-month comparative costing. Host Technology provides it for a management decision.

FTTO vs FTTH decision checklist

1. List critical uses (voice, VPN, point of sale, backup, video meetings).
2. Estimate the throughput peak and sensitivity to a 4-hour outage versus 24 hours.
3. Compare real GTR / penalties of the offers, not only the monthly price.
4. Visit the technical room and the possible cable route.
5. Cost 4G/5G backup in both scenarios.
6. Validate QoS and VLAN with Host before the operator order.
7. Plan link monitoring inside managed IT.

In an SD-WAN, a branch FTTH link can serve as the headquarters’ secondary link. What matters is the tested voice failover policy.

Multi-site on the Côte d'Azur

A headquarters on FTTO and branches on FTTH, linked by VPN or SD-WAN, is a common design. What matters: a consistent QoS policy for voice and a documented failover. Host Technology unifies the design so each PACA address plays the same role in the network.

Without LAN integration, you pay a GTR on a link while the business stays down because of a switch. The integrator avoids that blind spot.

After the choice: LAN integration

Firewall, Wi-Fi, telephony, backup: fiber is only the pipe. Host follows connection with integration to avoid the gap between “ONT lit” and “business operational.” That is where the local integrator creates value compared with a simple subscription.

Review the choice at each site opening or sharp rise in headcount: what was enough for 15 people can become tight at 40 with dense VoIP.

• Compare guaranteed throughput, not only the maximum speed displayed.
• Check the GTR, its exclusions, support hours, and penalties.
• Cost connection, hardware, cellular backup, and monitoring over three years.
• Test VoIP quality at busy hours before any final decision.
• Plan growth in cloud backups and new sites.
• Document the demarcation point between the operator and the internal network.

The FTTO or FTTH decision must end in an arbitration note that management can understand. It brings the monthly cost together with the cost of an hour of downtime, exposed revenue, and client commitments. In a seasonal SME on the Côte d'Azur, the value of continuity varies sharply between January and August. Host Technology therefore recommends a normal scenario, a failure scenario, and a thirty-six-month path. This approach avoids overpaying for unnecessary dedicated fiber or, the other way around, discovering too late that a shared offer does not cover the business need.

The choice must finally be reassessed when headcount, the Wi-Fi estate, or backup volume grows. An annual measurement of useful throughput, incidents, and resolution time shows whether the offer still fits. Host Technology sets these figures against invoices and upcoming projects. This review can lead to keeping FTTH, strengthening 4G/5G backup, or preparing FTTO before a site opening, without waiting until saturation is visible to clients.

FAQ: frequently asked questions

What is the essential difference between FTTO and FTTH?

FTTH uses shared infrastructure whose performance and restoration depend on the operator offer. FTTO generally provides dedicated access, guaranteed throughput, and an SLA with a contractual GTR. That does not automatically make the whole system more reliable: the firewall, switches, and cabling remain the company’s responsibility. Host Technology therefore assesses the access and the LAN together. The relevant choice is the one that respects the acceptable outage risk, not the one that displays the largest number of megabits.

Is professional FTTH enough for VoIP?

Yes, in many SMEs, if the number of calls stays reasonable, if the upload does not saturate, and if QoS and the voice VLAN are correctly configured. FTTH without a strong guarantee should still be completed by tested 4G/5G backup. In a Cannes hotel in peak season, or a practice whose switchboard is vital, load variations can justify FTTO. Host Technology measures latency, jitter, and real usage before recommending a service level.

Does a four-hour GTR guarantee a maximum of four hours of unavailability?

Not necessarily. The start of the clock, the hours covered, the exclusions, and the exact scope must be read. The GTR usually concerns the operator link up to the delivery point, not a failure of the firewall or the core switch. Four hours can also be too long for reception or a point of sale. Cellular backup then keeps the service up during restoration. Host Technology monitoring timestamps the incident, provides useful measurements, and follows escalation with the operator.

What design should you choose for several sites in PACA?

A headquarters concentrating servers, backups, or the IPBX can receive FTTO, while branches use professional FTTH with 4G/5G backup. A controlled VPN or an SD-WAN then applies a consistent security and QoS policy. The same operator does not have to be imposed in Nice, Cannes, and Monaco if governance is centralized. Host Technology maps the links, tests failover, and monitors each tunnel so disparate subscriptions become a coherent infrastructure.

How does Host Technology help choose the fiber?

The support starts from use: IP telephony, cloud access, backup, client Wi-Fi, VPN, and continuity obligations. A visit validates the cable route, the rack, patching, and backup coverage. Host Technology then compares FTTO, FTTH, and hybrid solutions with costs, lead times, GTR, and impacts on the business-continuity and disaster-recovery plan. The company receives a reasoned recommendation and a LAN integration plan, which avoids ordering high-performing fiber without preparing the network that must use it.
