Gr 3108 Core is a standard that specifies the generic requirements for network equipment in the outside plant (OSP) of a telecom network. OSP refers to the physical infrastructure that connects the central office to the customer premises, such as cables, poles, cabinets, vaults, huts, and towers. OSP equipment must be able to withstand various environmental conditions, such as temperature, humidity, salt fog, wind, rain, snow, ice, lightning, and vandalism. Gr 3108 Core defines four classes of OSP equipment based on the degree of protection and exposure to the elements:
Class 1: Equipment in controlled or protected environments, such as controlled environmental vaults, huts, cabinets, telecom closets, or residential locations. These environments have active heating and cooling systems that maintain the temperature between -5C (23F) and 50C (122F) and the humidity between 5% and 85%. The equipment must be able to perform initial, cold, or hot startup throughout the entire temperature range and continue operation if a single fan fails.
Class 2: Protected equipment in outside environments, such as outdoor enclosures, customer premise locations, garages, attics, or uncontrolled warehouses. These environments have extended temperature range of -40C (-40F) to 65C (149F) and the same humidity range as Class 1. The equipment must be able to perform initial startup at -40C (-40F) and hot startup at 65C (149F). The equipment must also be able to withstand salt fog exposure for up to 30 days.
Class 3: Protected equipment in severe outside environments, such as pole-mounted or pad-mounted enclosures. These environments have extreme temperature range of -40C (-40F) to 75C (167F) and the same humidity range as Class 1. The equipment must be able to perform initial startup at -40C (-40F) and hot startup at 75C (167F). The equipment must also be able to withstand salt fog exposure for up to 90 days.
Class 4: Products in unprotected environment directly exposed to the weather, such as tower-mounted or rooftop-mounted equipment. These environments have the most severe temperature range of -40C (-40F) to 85C (185F) and the same humidity range as Class 1. The equipment must be able to perform initial startup at -40C (-40F) and hot startup at 85C (185F). The equipment must also be able to withstand salt fog exposure for up to 180 days.
The Gr 3108 Core standard also defines the mechanical and electrical testing criteria for OSP equipment, such as vibration, shock, drop, earthquake, wind loading, fire resistance, surge immunity, electromagnetic compatibility, grounding and bonding, safety, and reliability. The standard helps ensure that the OSP equipment will operate reliably over its expected lifetime and provide high-quality service to the customers.
