Juniper BTI7802

Product Overview

Legacy wavelength-division multiplexing (WDM) systems can’t meet the capacity and price/ performance demands of today’s metro networks. Today’s content providers, colocation providers, and service providers require a new generation of extremely compact and simple-to-manage 100/200 Gbps optical platforms to interconnect data centers and support contemporary applications.

The BTI7802 Packet Optical Transport System provides largescale 10 Gbps, 100 Gbps, and 200 Gbps wavelength capacities with industry-leading density and performance.

Product Description

The Juniper Networks® BTI7802 Packet Optical Transport System is specifically designed to meet the unique power, space, and manageability requirements of access networks and small sites with limited space. Ideal for end-customer deployments and edge aggregation applications, this compact platform supports up to eighty 10 Gbps, eight 100 Gbps, or four 200 Gbps interfaces in a cost-effective 3 U footprint. The BTI7802 leverages a modular, flexible, pay-as-you-grow architecture.

Architecture and Key Components

At the heart of the BTI7802 are flexible Universal Forwarding Modules (UFMs), each capable of switching up to 400 Gbps. UFMs can be equipped with 10 Gbps, 100 Gbps, or 200 Gbps interfaces, providing the flexibility to support a wide variety of muxponder and transponder connectivity. Optimized for metro and regional networks, the BTI7802 supports a wide range of interfaces, including 10 Gbps, 100 Gbps, 200 Gbps, OTU2, OTU4, and OC-192/STM-64.

The BTI7802 provides a seamless upgrade path from 10 Gbps to 200 Gbps, as well as an easy migration to future higher bandwidth interfaces. Integrated reconfigurable optical add-drop multiplexer (ROADM)-on-a-blade modules, optional amplifiers, and protection switches satisfy diverse capacity, span and reach requirements. The BTI7802 costeffectively optimizes equipment expenses to enable increases in the capacity of existing networks and support new service deployments.

The SDN-enabled BTI7802 is supported by the comprehensive Juniper Networks proNX software product line that streamlines network operations, as well as open APIs that simplify integration with external operations and business support systems (OSS/BSS). The proNX software enables easy integration with back-office systems and applications through open RESTful APIs. It provides point-and-click service provisioning, fault and performance monitoring, and troubleshooting for the BTI7802. It also delivers a concise view of the health and performance of all BTI7800 networking platforms, enabling more proactive and efficient network management.

A carrier-grade solution, the BTI7802 supports redundant processors, power supplies, and service modules. The BTI7802 features a multi-slot, multichassis architecture for ultimate flexibility and scalability. Ideal for small site and end-customer deployments, the platform also supports AC and DC power options and in-band monitoring.
