The 3905 is a compact and rugged Ethernet service delivery platform purpose-built to support small cell mobile backhaul applications. It supports all of the necessary features that mobile network operators and wholesale mobile backhaul service providers require to guarantee strict and differentiated SLAs.

Features

Provides high-capacity, next-generation GbE service delivery purpose-built for outdoor small cell mobile backhaul networks

Includes environmentally hardened and physically secure enclosure and electronics (-40°C to +65°C), providing flexible deployment options

Zero-Touch Provisioning for rapid, secure, and error-free turn-up of small cell packet-based services

Supports 2 UNI ports with dual connectors: RJ-45 10/100/1000Base-TX and Small Form-factor Pluggable (SFP) optical 100/1000BaseX

Supports 2 GbE NNI ports via SFP optics

Features state-of-the-art hardware design and field-proven, modular, Service-Aware Operating System (SAOS) for reliability and resiliency
