Although the most rugged types of telecom equipment can operate without heating and cooling, most outdoor telecom cabinets are designed to comply with the GR-3108-CORE Class 1 specification, which requires that the internal temperature of the cabinet is maintained between 41°F (5°C) and 104°F (40°C).
The heat load of modern telecom cabinets is often high, and it’s usually necessary to install enclosure cooling equipment to maintain the internal temperature below the higher limit specified by GR-3108-CORE. Enclosure heating may also be required in colder regions.
Telcordia specifications GR-487 and GR-3108: The telecom industry has a long history of outdoor plant cabinets and has developed detailed specifications such as the Telcordia Requirements for Electronic Equipment Cabinets (GR-487) and the GR-3108, which specifies equipment testing criteria.
Enclosure heating may also be required in colder regions. Apart from the need to ensure telecom equipment conforms to the required specifications, the industry must ensure that solutions devised are such that overall costs are minimized while reliability is enhanced.
