Specifically, of the 6.95 million fiber optic connections installed in Spain, 2.71 million were in the province of Madrid, while 1.59 million were in Barcelona, ​​totaling 4.3 million connections, or 62% of the total.
The CNMC report indicates that Madrid, with 33 lines per 100 inhabitants, Barcelona (31.3), and Gipuzkoa (29.5) are the three provinces with the highest fixed broadband penetration, while the national average is 26.2 lines. Conversely, the provinces with the fewest broadband connections were Jaén (17.9), Murcia (18.1), and Huelva (18.2).
Esther Gómez, General Manager of FiberNet, a Spanish company dedicated to the development and manufacture of fiber optic communications products, explains that "Madrid and Barcelona, ​​not forgetting the Basque Country, are where most of the fiber optic business is concentrated, both at the consumer and business levels."
At the end of 2012, Madrid and Barcelona accounted for 73.4% of the fiber optic connections installed in Spain. Furthermore, last July, fiber-to-the-home (FTTH) lines surpassed one million connections for the first time, reaching 1,025,056 lines. Fiber optic lines were the most subscribed and increased by 91,237 new connections, 118.6% more than the previous year. In contrast, ADSL and coaxial cable (HFC) connections registered losses (-67,951 and -12,203 lines respectively), which demonstrates the shift towards fiber, according to data from the CNMC (National Commission for Markets and Competition).
According to Esther Gómez, General Manager of FiberNet: “The CNMC data is very positive and reflects how more and more users and companies are demanding cutting-edge technology that can offer them greater benefits such as speed and security.”

FiberNet has more than 25,000 optical channels installed in Spain and a presence in 85% of the country's main data centers.
