# Service description

***

An optical distribution frame (ODF) is designed to provide cable interconnections between communication facilities. It integrates fiber splicing, fiber termination, fiber optic adapters, connectors, and cable connections in a single unit. Additionally, it functions as a protective device, safeguarding fiber optic connections from damage.

### Technical specification

The ODF service offers solutions for pre-cabling and termination of optical services in a colocation rack. We typically pre-install our racks with an ODF that meets the specifications below. Each rack is supplied with six pairs by default.
