    Compramos 5 S5720-36C-EI-28S-AC de telecomate.com y solo nos tomó 5 días entregarlos en Argentina. Su agente de carga es excelente.

    Los productos son nuevos y los módulos ópticos también son originales de Huawei. Hemos probado dos de ellos y estamos muy satisfechos con las capacidades de forwarding y switching.

    Se lo recomendaré a mi amigo operador.
