Fiber internet features: what to check on the order form

A fiber order form has more choices on it than people expect, and the choices are made by whoever fills it in, which is usually a salesperson optimizing for a quick yes. The glass is the same whatever you tick. What differs is what arrives at your wall, how it behaves at the busy hour, and what you can do with it later.

This page goes through the fiber internet features on those forms: what each one is, who needs it, and the question that gets a straight answer.

Most of those choices have industry names, and knowing them is what lets you read the form. Shared access sold over fiber is often a PON — passive optical network — product. The full-speed circuit is dedicated internet access, or DIA, and its Ethernet versions are an Ethernet private line (EPL) and an Ethernet virtual private line (EVPL). The speed the provider answers for is a committed information rate, or CIR.

What to take away

Symmetry

Most connections give you far more capacity downward than upward. Fiber is

Who needs it: anyone who is seen and heard rather than only reading. Video meetings, phone calls, offsite backup, file sync, camera systems, remote staff connecting in, and anything customers reach on your premises all run upward. An office that feels fine while browsing and poor while on calls has almost always been sold an asymmetric product.

Ask: what is the upward figure, and is it committed or a ceiling? A committed figure is written into the contract as a committed information rate — the CIR — a number the provider answers for, and you check it by testing at the provider's demarcation point rather than by browsing. A ceiling is only the speed of the port and nothing more. Fiber is normally sold symmetric, the same figure up and down, so a quote with a smaller upstream number is a product choice you can push back on. The reasoning behind sizing by what happens at once rather than by headcount is in business internet. For a first estimate before you speak to anyone, the FCC — the Federal Communications Commission — publishes a household broadband guide that shows how simultaneous use adds up, and a broadband speed guide that turns single activities into figures.

Shared or dedicated

The same glass can deliver two different products. One splits a strand

Which one is right depends on how much the bad afternoon costs you. What the question sounds like on an order form is: is this shared access or a dedicated circuit, and what exactly is committed? Shared access is often a passive optical network, or PON, product, where one strand is split among several premises. The dedicated version is dedicated internet access — DIA — and the Ethernet versions of it are an Ethernet private line, EPL, or an Ethernet virtual private line, EVPL. An honest answer names one or the other without hedging.

The upgrade path

On most other media, more capacity means new equipment or new construction.

That makes an underappreciated feature: the ability to change capacity without another install. Ask, before ordering:

Then buy what the busy hour needs today, knowing what growth costs in time — and whether a change is a phone call or an engineer visit.

The hand-off

The circuit ends at a box the provider owns. What comes out of that box, and

who owns the next box, is a choice:

Ask which you are getting, who can log in, whether the configuration can be exported, and whether voice prioritization is available. If the office will run phones over it, the network requirements in VoIP systems apply to whatever box sits at the edge.

Addresses

A fixed public address, or several, is an order-form option on most business

Ask how many are included, how many can be added, and whether they are fixed for the life of the contract. Blocks are quoted in shorthand: a single address, or a small block such as a /30, which gives two usable addresses, or a /29, which gives six. Then record them in the setup notes, because an address that was configured into a supplier's allow-list three years ago and then forgotten is how migrations go wrong.

Two paths into the building

For a business that cannot tolerate an outage, a second circuit that enters

the building by a different route, terminates on different provider equipment, and follows a different path to the provider's network is a feature that can be ordered, sometimes, at a price that depends on what already exists.

Ask whether diverse entry is available at your address, what "diverse" means in their offer, and where the two paths first meet. Ask as well whether the two paths will carry the same public addresses and fail over on their own, which in practice means running a routing protocol such as BGP between your equipment and the provider's — a feature not every small office product supports. Then compare that with a second connection on a different medium altogether, which is often cheaper and more genuinely independent. The pillar on fiber internet covers where the physical build risks sit, which is what a second path is protecting you against.

The repair commitment

The repair commitment is the line on the form where a figure matters most, and it is usually the least discussed. Two things need pinning down: what starts the clock, and what the provider owes you when it misses.

The clock normally starts when the trouble ticket is opened, not when the fault appears, so the time you spend on the phone is your own. The commitment itself is written into the contract as a response and repair interval, and the remedy for missing it is a service credit against the monthly charge. Ask for both in writing, ask what the credit is, and ask whether the clock pauses while the provider is waiting on you. A commitment that lives only in a sales conversation is not a commitment.

The order form in one table

The table only pays off if you leave with answers rather than more questions. Write down the committed upward rate, whether the circuit is shared access or a dedicated circuit, what event starts the repair clock and what the provider owes you if it runs late, how many fixed addresses are included, the monthly charge for each option you ticked, the term and what an early exit costs, and where the two paths would first meet. Delivery time turns on whether the building is already lit: an address the provider already serves can be turned up without construction, while an unlit building needs a survey and a build first. If a salesperson cannot put those answers in writing before you sign, the form is not filled in yet.

Common questions

Is more capacity the feature to prioritize?

Rarely. Symmetry, a dedicated circuit and a good hand-off change daily work more than a larger figure does. Capacity you do not use at the busy hour does nothing.

Does the building's internal wiring matter?

Yes, and it is outside the provider's scope. A circuit is only as fast as the slowest cable and switch between it and the desk. Have the internal wiring checked before blaming the circuit; the records that make that possible are in setup and troubleshooting.

Can I get a temporary capacity increase for an event?

Some providers offer it, some do not, and the answer depends on the equipment installed. It is a good question to ask at order time, because the answer tells you how flexible the product is.

What if the provider only offers one flavor?

Then the comparison is between providers rather than options, and a different provider may deliver a different product over the same glass. Ask.
