On the Matter of Ongoing Universities Strike in Nigeria {Re: USA Africa Dialogue Series - Ekiti State and Fiber-Optics

Boloaji, my broda,

Again, I  want to express my appreciation for the positive contribution folks like you and Fayemi and Fashola, Obi, Oshiomhole, and others seem to be making. I also appreciate your sharing the good news with your networks including those of us on this side of the pond. How is your university doing? Hope it is not affected much by the current strike. Take care.

-Okey

ADO-EKITI, EKITI: in the bid to actualise the Ekiti Digital Transformation Programme of
the Governor Kayode Fayemi administration, the state government would commence the laying of fibre optic cables in designated areas of the state this week.

Governor Fayemi will be performing the ground-breaking ceremony of the Phase 1 of the optical fibre cable laying project for Ado-Ekiti, the state capital, on Tuesday (September 3, 2013). The project, which is an outcome of the MOU signed between the Ekiti State Government and IPNX Nigeria Limited in June 2013, is in linewith government's initiative of transforming Ekiti State into a digital state.

The laying of the fibre optic cable, which is expected to enhance effective internet connectivity in the state, is expected to last for eight weeks.

Fibre optics cable is the fastest means of transmitting data. A single strand of fibre cable can transmit up to 100 gigabits per sec, making it possible to simultaneously carry video, internet and telephone calls.

Due to its capacity for almost limitless data speed, fibre-optics is the true enabler of broadband services. With the infrastructure of fibre optics based broadband being available in Ekiti State, the foundation is being laid for a transformation in the way Ekiti residents live, work, do business and
play.

Fayemi: digital networking'll improve businesses

Posted by: Sulaiman Salawudeen, Ado-Ekiti in News 1 hour ago 

Ekiti State Governor Kayode Fayemi has said the fibre optics cables laid in the state will ease internet transactions and improve the quality of life. 

The governor spoke with reporters yesterday on the commencement of the Phase I of the Optical Fibre-Laying Project in Ado-Ekiti, the state capital. 

Fayemi said the project, which will last eight weeks, was the outcome of a Memorandum of Understanding (MoU) signed by the state and ipNX Nigeria Ltd in June. 

He said the project would help Ekiti to actualise its digital transformation programme. 

The governor said: "Fibre optics cable is the fastest means of transmitting data. A single strand of fibre cable can transmit up to 100 gigabytes per second, making it possible to simultaneously carry video, Internet and telephone calls. 

"Due to its capacity for almost limitless data speed, fibre optics is the true enabler of broadband services. With the infrastructure of fibre optics based broadband available in Ekiti State, the foundation is being laid for a transformation in the way Ekiti residents live, work, do business and play. 

"The first phase will cover about 8km from the Government Data Centre to Tantaliser, Fajuyi Park, Bank Road, State Secretariat, GRA/Onigari and Christ's School axis. 

"Essential services to be provided via the fibre cables include: high speed Internet access to home and offices at an affordable price; Wi-fi hotspot at Fajuyi Park; telephone call services; video conferencing; Cable TV on demand (with many channels); safe city security cameras; e-Education and e-Health." 

Special Adviser to the Governor on Infrastructure Kayode Jegede said the project was being done on a Public-Private-Partnership (PPP) basis. 

Jegede said it would curb crime and create jobs. 

The firm's Managing Director and Chief Executive Officer, Ejovi Aror, said Ado-Ekiti would be the fourth city in Nigeria to have the fibre optics technology. 

He said improved Information and Communication Technology (ICT) would improve socio-economic activities.

On Copper and Fiber Optics Network Transmissions  A Primer

 

LANS

These can still use  (1) copper cables (unshielded-twisted-pair cable (UTP) ), including CAT 5/5e/6 cabling for Gigabit Ethernet usage; or  (2) coax cabling  as different from (3) optical fibers.  [Optical fibers are increasingly replacing coax in network transmissions, but UTP will be around for the foreseeable future, even as fiber becomes more and more used for higher bandwidths (50Mb/s, 150 Mb/s and above).]

LAN	Bandwidth
Ethernet	10 Mb/s
FDDI	100 Mb/s
Fast Ethernet	100 Mb/s
ATM	55, 155 Mb/s
Gigabit Ethernet	1,000 Mb/s (1 gigabit/s)
10 Gigabit Ethernet	10 Gb/s

 

 

Fiber-Optics Transmission

SONET - Synchronous Optical Networking  (Uses OC (Optical Carrier) Levels to describe bandwidths). Used Mainly in the USA and Canada

SDH - Synchronous Digital Hierarchy  (Uses STM (Synchronous Transport Module) Levels to describe bandwidths (Used Mainly in the rest of the world apart from USA and Canada)

SONET and SDH two standardized protocols that transfer multiple digital bit streams over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs)
