The Zhone MXK-190 provides next generation 1U GPON OLT features in a compact, hardened form-factor that makes it easy and cost-effective to deliver uncompromising triple play services throughout the serving area. Models are available with 4 or 8 GPON Ports. The ITU-T standard GPON technology provides 2.5Gbps downstream and 1.25 Gbps upstream bandwidth over a passive optical network on each of the 4 or 8 ports per unit. GPON provides one of the most cost-effective ways for operators to deploy fiber-based services to the home, business, or node. With GPON splitters that can be co-located with at the CO or installed remotely in the network, the service provider can choose the network architecture that finds the right balance between capital cost optimization and scalability.
