Cabling Transponder Modules

Chapter 2 Quick Installation Procedures

Installing Cisco ONS 15540 ESP Hardware

Step 3 Lift the latch handle on the extended range transponder module and insert the module carefully into the motherboard slot while guiding the upper and lower edges of the module in the tracks until its connectors come into contact with the backplane connectors. You hear a click when it is connected.

Step 4 Push the latch on the module down to secure the module in place.

Table 2-5lists the LEDs for the extended range transponder module.

LED	Status	Description

CLIENT RX	Green	Data is received on the client side.

TRUNK RX	Green	Data is received on the trunk side.

CLIENT TX	Green	Client side transmit laser is enabled.

TRUNK TX	Green	Trunk side transmit laser is enabled.

To install fiber-optic cables in the Cisco ONS 15540 ESP, a fiber cable with the corresponding connector type must be connected to the transmit and receive ports on the modules. On Cisco ONS 15540 optical ports, the top connector is Transmit and the bottom connector is Receive. Label the transmit and receive and the working and protection fibers at each end of the fiber span to avoid confusion with cables that are similar in appearance.

Step 1 Place the connector in front of the connection point on the transponder module faceplate. Each transponder module has at least one transmit and one receive connector to create an optical carrier port.

Step 2 Align the keyed ridge of the cable connector with the receiving slot on the faceplate connection point. Gently push the cable connector into the faceplate connection point until the connector snaps into place.

Step 3 Route fiber cables through the cable retaining clips on the optical card faceplate into the cable management tray on the bottom of the shelf assembly.

Step 4 Route the fiber cables from the cable management tray out of the right side of the shelf assembly through cutout holes from the cable management tray.

Cabling Mux/Demux Modules

This section describes the connections between pairs of mux/demux modules and between mux/demux modules and mux/demux motherboards in the Cisco ONS 15540 ESP. The assumption is made that the motherboard and modules are already installed and checked.

ONS 15540 specifications

Cisco Systems ONS 15540 is a high-capacity Optical Network System that plays a vital role in modern telecommunications by providing scalable and reliable transport solutions for service providers. Designed to accommodate the rapidly increasing demand for bandwidth, the ONS 15540 allows for seamless integration of voice, video, and data services over a single network infrastructure.

One of the standout features of the ONS 15540 is its ability to support both SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) protocols, enabling interoperability between different equipment and networks. This compatibility makes it an attractive solution for carriers looking to optimize their existing infrastructure while also preparing for future growth. The system is capable of delivering line rates of up to 40 Gbps, making it suitable for high-traffic environments.

The ONS 15540 employs advanced wavelength division multiplexing (WDM) technology, which allows multiple data streams to be transmitted simultaneously over a single optical fiber. This capability maximizes the utilization of existing fiber resources and significantly increases bandwidth availability. The system supports both CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) configurations, offering flexibility to meet diverse network needs.

Another significant characteristic of the ONS 15540 is its modular architecture. This design enables service providers to easily upgrade and expand their systems by adding new line cards or service modules without significant disruption. The ONS 15540 accommodates various types of interfaces, including Ethernet, TDM, and video, ensuring the system can support a wide range of applications.

In addition to its hardware features, the ONS 15540 includes sophisticated management capabilities through Cisco's comprehensive management tools. These tools allow network operators to monitor performance, provision new services, and perform troubleshooting efficiently. With built-in redundancy and fault-tolerant features, the system ensures high availability and reliability, critical for service providers that require 24/7 operation.

In summary, the Cisco Systems ONS 15540 optical networking system provides a robust solution for carriers seeking to enhance their network capacity and flexibility. With its support for multiple protocols, advanced WDM technology, modular architecture, and management capabilities, the ONS 15540 stands out as a powerful asset for meeting the demands of today’s communication landscape.
