Wavelength is an unstructured Optical Capacity service (zero layer) based on a Dense Wavelength Division Multiplexing (DWDM) technology that has been implemented on our network.

It is designed to facilitate singular or complex optical point-to-point connections and utilize the most appropriate structure solution determined by the given capacity needs. The service is contracted with the associated optical transmission elements based on the design, planning and control of the complementary elements of the customer’s network. Depending on the exact requirements and based on a feasibility study, this capability can be configured as a self-protected lambda on various routes, with delivery via interface 1 + 0 at the extremes, or as independent linear lambdas. In the latter case, the customer must provide the protection plan for the lambdas.

DWDM is an optical communications technology that uses multiplexer diverse wavelengths (lambdas) on the same fibre optic. Each wavelength travels in a way that is modified according to the information it carries (voice, video, data, etc).

  • Availability of bandwidth supporting large zero layer capacity.
  • Transparent Wavelength channels
  • Flexible usage applications combined with sharing options across multiple devices
  • The Wavelength service is customizable and requires dedicated resource to leverage the full capabilities. In contrast, our Private Line service, which is more structured in terms of service specifications and delivery, allows customers to focus on their core business.

Telxius, leader in capacity services in Latin America, is backed by Telefonica Group’s reliability and strength. It is also the first fixed and mobile operator in its markets and one of the top 10 international carriers worldwide.

  • More than 45,000 kilometers of fibre-optics providing connectivity between Latin America, the USA and Europe.
  • From initial Capacity 1.92 Tbps currently expanded to 19,2 Tbps.
  • Automatically restored
  • Open Access and no restrictions end-to-end
  • State-of-the-art technology in the SDH and SONET standard and in DWDM wavelengths 40 Gbps and 100 Gbps.
  • Personalised customer service with two in house network operation centres that operate continuously 24 hours per day, 365 days per year.
  • Flexibility in hiring arrangements.
  • First looped network in Latin America. Operational since April 2001.

Service modalities:

There are two ways of contracting this service:

  • Wavelength backbone (services between POP’s)

Wavelengths format transparent 10Gbps SDH / SONET and Ethernet LAN PHY and WAN-PHY in linear configuration and delivery are geographically redundant by 1 +0 in between the POPs distributed via the Telxius network, based on DWDM lines technology with recommendations from the ITU-T.

Special solutions based on wavelengths of 40 Gbps and 100 Gbps are redundant linear and geographically.

  • Wavelength City to City

Point to Point Connectivity (client interconnection dependencies) between cities in the United States, Central America, South America, Spain, Portugal and the UK, with transmission speeds of 10 Gbps, 40 Gbps and 100 Gbps redundant linear and geographically.

This service is made up of the following basic components:

  • Wavelength backbone Network (10Gbps, 40Gbps and 100 Gbps)
  • Network access (backhaul), connecting Landing stations Telefonica Global Solutions with major cities at levels of 10Gbps, 40Gbps and 100 Gbps lambdas
  • Colocation: Space necessary for that client to install their transmission equipment in Telxius’ Points of Presence.


  • Unstructured circuits with equipment and interfaces compatible with multiplexor equipment and interfaces from a great variety of suppliers in the industry.


  • Establishing point to point connections between locations
  • Private Networks developed by the customer
  • Offers the ability to restore customer’s network

Sales modalities:

The options, for the two modes of service are:

  • IRU (indefeasible Right of use)

IRU offers an effective method of securing a long term lease on a portion Telxius’ network. The IRU is granted for 10 or 15 years.

  • Leasing

In order to serve those customers not willing to commit to long-term investments, Telxius also provides short-term arrangements. To meet their needs, Telxius offers capacity leases with terms ranging from 1, 2, 3, 4 and 5 years. Plus, to increase the customer’s ability to adapt to a constantly changing environment, it also offers a Lease to Buy Option

Price and Payment Terms

  • IRU (indefeasible Right of use)
  • Installation: Once with the activation notice (NRC Non Recurring Charge)
  • IRU fee payment (advance payment only after activation).
  • O&M (Operation and Maintenance): Must be paid quarterly on an annual basis
  • Rental
  • -Installation: Pay only after notification of activation (NRC Non recurring cost).
  • Pay monthly recurring fee (MRC Monthly Recurring Cost).


Service quality parameters on net:

  • Service Availability: 99.95% (between POP’s of Telxius)
  • Round trip delay: Example Boca Raton-Sao Paulo less than 110ms (round-trip time).
  • Troubleshooting: maximum 4 hours
  • Service Repair Times (Dry plant): 8 hours
  • Service Repair Times (Wet plant).: 15 hours
  • Installation Time: less than 30 days


  • Compliance with international standards ITU-T G.691 for optical interfaces, at the interconnection points with third party networks and clients.
  • Restoration: restoration of the Operator Client’s Network by connecting to the Telxius network
  • Access Network (*): Connects the Telxius’ Points of Presence with the main cities and the Clients’ Points of Presence
  • Co-location (*): provides space in the Telxius installations for clients that want to install their communications and network equipment in Telxius’ land station, or in the Points of presence (POPs).
  • Unified Management (*): Complete management of the client’s network, including equipment co-located in Telxius’ Installations.

(*) The Access Network, Co-location and Unified Management products are not available separately subject to the corresponding regulatory approvals.

Wavelength and Collocation Telxius’ services can be packaged in a competitive bid optimizing network resources, segments of the local loops and minimizing the activation times with local access circuit.
