Fiber optic cable linking Cuba to Jamaica active
By Juan O. Tamayo
Cuba has activated a branch of its submarine fiber optic cable that
connects to Jamaica, giving it greater bandwidth and a backup in case
the main leg to Venezuela is not available, according to a U.S. company
that monitors global Internet traffic.
Doug Madory, senior analyst at Renesys in Maine, said that on May 13 the
company noticed that ETECSA, the Cuban government's telecommunications
monopoly, had started to receive international Internet service through
Cable & Wireless Jamaica.
That shows Havana is now using the Jamaica branch of the ALBA-1
submarine cable that connects Venezuela and Cuba, Madory noted. Cuba
just started carrying Internet traffic on the main Venezuela leg in
January, although the cable was finished two years ago.
Madory said the Jamaica link gives Havana greater bandwidth for its
international Internet connections, as well as a backup in case the leg
of ALBA-1 to Venezuela is interrupted.
Until January, ETECSA was routing all Internet traffic through three
satellites, which have much slower and expensive Internet connections.
U.S. traffic to Cuba, for instance, had to travel about 43,000 miles —
up to the satellites and then back down.
The 1,000-mile-long Cuba-Venezuela cable began carrying voice traffic
for international calls last August, according to a Jan. 24 note by
ETECSA, officially the Cuban Telecommunications Enterprise.
But on Jan. 10, ETECSA technicians "began to carry out quality tests on
Internet traffic," the note added. "These are being carried out using
real traffic from and to Cuba, with the goal of normalizing this
The note added that even after the cable is fully operational, Cubans
will not get increased or cheaper access to the Internet because the
overall network on the island still requires improvements.
Cuba has one of the lowest Internet connectivity rates in the Western
