GLO-1

GLO-1 is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GLO-1 rather than just read about it. In short: The GLO-1 (Globacom-1) submarine communications cable is a cable system along the west coast of Africa between Nigeria and the UK, owned by Nigerian telecoms operator Globacom. The submarine cable system is 9,800 km long, and became operational in 2011 with a minimum capacity of 640 Gbit/s.

Key takeaways

GLO-1 belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GLO-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GLO-1 from memory before moving on to harder problems.

Reference excerpt

The GLO-1 (Globacom-1) submarine communications cable is a cable system along the west coast of Africa between Nigeria and the UK, owned by Nigerian telecoms operator Globacom. The submarine cable system is 9,800 km long, and became operational in 2011 with a minimum capacity of 640 Gbit/s. A project of Globacom, Nigeria's 2nd largest telecoms provider, total capacity of the system is now advertised as 2.5 Tbit/s. The cable's link To Ghana was turned up in April, 2011.

Landing points The main cable landing points are:

Lagos, Lagos State, Nigeria. Accra, Ghana Dakar, Senegal Nouakchott, Mauritania Casablanca, Morocco Sesimbra, Portugal Vigo, Spain Bude, UK

Security breach In February 2018, The Sunday Times reported that the infrastructure for the UK landing site of the Apollo, GLO-1 and Europe India Gateway cables had been found almost entirely unprotected. Their reporter was able to reach the premises without being challenged, and found the door to the generator room unlocked and left ajar. Vodafone, who manage the facility, said that he had not reached critical equipment and "would not have been able to interrupt the operation of the facility."

Worked examples

Example 1 — a first encounter with GLO-1

Start with the simplest possible case. Write down what GLO-1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GLO-1 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GLO-1 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GLO-1

In research: GLO-1 appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses GLO-1 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: GLO-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2011 establishments in Africa, 2011 establishments in Europe, Infrastructure in Africa, so understanding it makes those chapters shorter.
In everyday life: Look for GLO-1 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GLO-1 in simple terms?

Why does GLO-1 matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GLO-1?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
