Chapter 5 Connecting Optical Cables

Connecting Optical Isolators

Caution When connecting Cisco Metro 1500 series systems, you must adhere to the minimum remote link budget, as called out in Table A-9 on page A-15. If you do not adhere to this minimum budget, you might damage the receivers of the channel cards. This damage can only be repaired at the factory and is not covered by the warranty.

Connecting Optical Isolators

The Cisco Metro 1500 series optical isolator allows direct transmission from a WCM over a remote (or trunk) fiber. The optical isolator enables a WCM to bypass the multiplexer/demultiplexer (MUX/DMX) module in the system chassis. By connecting the WCM to the optical isolator through fiber jumpers, you can transmit directly over the remote fiber and obtain an additional 3 dB to 5 dB for use in your optical budget.

The optical isolator minimizes optical back reflection. Optical back reflection is common in fiber-based transmissions. Back reflection is a small amount of light that is reflected back towards the transmitting optical component. The optical isolator absorbs this reflected light so that the transmitting optical component operates with minimal interference.

Installation Notes

The optical isolator is connected directly to a jumper that extends from the remote connection of the WCM. The optical isolator sits between the WCM and the remote (or trunk) fiber. (See Figure 5-10.)

1500 specifications

Cisco Systems, a leader in networking and IT solutions, has a long history of providing innovative technologies for businesses of all sizes. One of their notable offerings is the Cisco Systems 1500 series, a robust and flexible networking solution designed to meet the demands of modern enterprises. The Cisco 1500 series is particularly recognized for its capabilities in delivering high-performance routing and switching services, ensuring reliable connectivity across various environments.

One of the main features of the Cisco 1500 series is its ability to operate in diverse environments, including branch offices and remote locations. Backed by Cisco's proprietary software, the 1500 series includes advanced routing protocols that enhance performance while optimizing bandwidth usage. This is crucial for businesses that rely on real-time data transmission for applications like voice over IP (VoIP) and video conferencing.

In addition to routing capabilities, the Cisco 1500 series is designed with enhanced security features. Integrated firewalls, intrusion prevention systems (IPS), and secure VPN options ensure that data remains protected from potential threats. The ability to implement rich security policies at branch locations is essential for organizations looking to safeguard sensitive information while maintaining regulatory compliance.

Another key characteristic of the Cisco 1500 series is its support for Cisco's Software-Defined Wide Area Network (SD-WAN) technology. This feature allows businesses to manage their WAN connections more efficiently, increasing agility and reducing costs. By utilizing software-based controls, organizations can optimize traffic flows and respond to changing network conditions in real-time.

Scalability is an essential aspect of the Cisco 1500 series, providing businesses the flexibility to grow without major overhauls of their infrastructure. The ability to support multiple connections and integrate seamlessly with cloud services makes the 1500 series an ideal choice for hybrid environments.

Additionally, the Cisco 1500 series is equipped with management and monitoring tools that enhance visibility into network performance. This includes Cisco DNA Center and other network management platforms that deliver insights, automate processes, and streamline operations.

In summary, the Cisco Systems 1500 series combines high-performance routing, robust security, support for SD-WAN, and scalability to meet the challenges of contemporary networking. As companies increasingly adopt digital transformation strategies, solutions like the Cisco 1500 series are vital for ensuring seamless connectivity, security, and adaptability in an ever-evolving technological landscape.
