Standards & Certifications Reference

Every number and rule on this site traces back to a published standard or a vendor document. This page is the map: which standard governs what, where each one shows up on this site, and which training programs teach these topics. It is a pointer, not the source — always read the current standard from the body that publishes it.

How to use this page

Use the tables below to answer two questions. First, "which standard defines this?" — so when you make a claim in a design or on a ticket, you can name the authority behind it. Second, "how do I get certified in this?" — so you can map the topics you've learned here to a recognized program. This page names standards and programs accurately by number/name; it does not reproduce their text and does not invent URLs or exam codes.

Common mistake — treating a training page as authoritative

Nothing on this site (including this page) is a substitute for the actual standard or the vendor data sheet. Course figures are teaching approximations. When a real design or acceptance depends on a value, trace it to its source of truth — the standard body's current publication or the exact component's documentation — before you commit it.

ITU-T G-series — fiber, grids, and transport

The ITU-T G-series recommendations define optical fiber types, the WDM channel grids, and the optical transport architecture. These are the backbone standards for everything on this site.

IEC — safety and test methods

IEC standards cover laser safety and the test/inspection procedures behind your acceptance data.

Standard	What it governs	Where it shows up here
IEC 60825	Safety of laser products — hazard classes and safe-handling requirements.	Amplification & Safety
IEC 61300-3-35	Fiber-optic connector endface inspection — the cleanliness pass/fail method.	Fiber Basics, Turn-Up
IEC 61280	Fiber-optic communication subsystem test procedures (insertion loss / OTDR method).	Testing & Loss Budget

TIA & Telcordia — cabling and component reliability

Standard	What it governs	Where it shows up here
TIA-568	Structured cabling — including fiber polarity/connectivity practice.	Fiber Basics, Turn-Up
Telcordia GR-1221	Reliability assurance for passive optical components.	Optical Transport
Telcordia GR-468	Reliability assurance for optoelectronic (active) devices.	Optical Transport, Ekinops360

How to verify a claim

Every figure you rely on should trace to one of two authorities. If you can't name which, treat the number as an estimate and go find the source before you commit it.

Standards bodies define the rules

ITU-T (fiber types, the DWDM/CWDM grids, OTN, optical safety and monitoring), IEC (laser safety, endface inspection, test methods), TIA (structured cabling/polarity), and Telcordia (component reliability). If the question is "what does valid mean?", the standard is the authority — referenced here by number; read the current edition from the body itself.

Vendor docs / BOM define the hardware

The card/optic data sheet and the current BOM/SKU list are the truth for receiver sensitivity, system budget, supported rates, reach, channel-to-port maps, and part numbers. A rate or reach that isn't in the Ekinops documentation for the exact SKU is not real — verify against Ekinops docs and the BOM.

Rule of thumb

Don't trust a number without a reference. If you can't name the ITU/IEC/TIA/Telcordia standard or the vendor data sheet a figure came from, it is an estimate — not a design input.

Certification map

These are real, recognized programs. Verify the current exam names, prerequisites, and details directly with each provider — the mapping below is by topic domain, and this page does not invent exam codes. Use it to see which topics on this site line up with which certification's domain areas.

FOA — The Fiber Optic Association

Vendor-neutral certifications. The base CFOT (Certified Fiber Optic Technician) plus specialist tracks including WDM/DWDM and design. FOA also publishes free "Fiber U" self-study courses and the FOA Reference Guide.

Best fit for: fiber fundamentals, connectors, testing, and WDM/design topics on this site.

Nokia — Optical Network Certification (ONC)

A vendor optical-networking certification program covering DWDM/OTN transport concepts and operations. Confirm current levels and exams with Nokia.

Best fit for: transport, OTN, and operations topics on this site.

Light Brigade — CONE

Certified Optical Network Engineer (CONE) — an optical-network engineering certification from Light Brigade. Confirm current curriculum and prerequisites with Light Brigade.

Best fit for: link engineering, OSNR/dispersion, and design topics on this site.

Site topics mapped to certification domains

Site topic	FOA (CFOT + WDM/design)	Nokia ONC	Light Brigade CONE

Domain names above are indicative groupings to help you plan study, not official exam blueprints. Confirm the real domain structure with each provider before you rely on it.

Ekinops training — the honest note

Ekinops offers instructor-led vendor training — typically progressing from DWDM basics, to the Ekinops360 platform, to Celestis NMS, and on to deploy/operate/maintain the equipment. However, Ekinops does not have a public named certification or academy the way the programs above do. If you want Ekinops-specific training, contact Ekinops for current course offerings and scheduling. Do not expect a public exam code — there isn't one.

Field checklist — using this reference

I can name the ITU-T standard behind a fiber type, grid, or OTN claim.
I know which IEC standard covers laser safety, endface inspection, and test method.
Before committing a number, I trace it to the standard or the vendor BOM.
Our org's real standards links have replaced the placeholders on this page.
I've picked a certification path (FOA / Nokia ONC / Light Brigade CONE) and verified its current details.
I understand Ekinops has vendor training but no public cert — and know to contact Ekinops for it.

1. Which ITU-T recommendation defines the DWDM frequency grid, and which defines the CWDM wavelength grid?

DWDM grid = ITU-T G.694.1 (C-band, 193.1 THz anchor, 50/100 GHz, flex-grid). CWDM grid = ITU-T G.694.2 (20 nm spacing). See WDM Basics.

2. A tech says "the endface passed inspection." Which standard defines that pass/fail?

IEC 61300-3-35 — fiber-optic connector endface inspection. It's the cleanliness pass/fail method behind acceptance. See Turn-Up.

3. Which standard family covers optical safety and automatic power reduction/shutoff on amplified systems?

ITU-T G.664 defines optical safety procedures (APR/ALS); IEC 60825 covers laser product safety classes. Both appear on Amplification & Safety.

4. You want a vendor-neutral cert that covers fiber fundamentals plus a WDM/design specialty. Which program?

FOA — the base CFOT plus its WDM/DWDM and design specialist tracks (and free Fiber U study material). Verify current details with the FOA.

5. Does Ekinops offer a public named certification?

No. Ekinops offers instructor-led vendor training (DWDM basics → Ekinops360 → Celestis NMS → deploy/operate/maintain) but has no public named certification or academy. Contact Ekinops for current training offerings.
