C H A P T E R 1 Applications The Cisco ONS 15216 EDFA1 provides bandwidth-on-demand to extend DWDM links by hundreds of kilometers. This manual describes how to install and operate the ONS 15216 EDFA1, which is a DWDM-enabling technology for multiservice ring DWDM networks.
Chapter 1 Applications ONS 15216 EDFA1 Operation Extending ONS 15454 Reach Distance The Cisco ONS 15216 EDFA1 can be used in conjunction with the ONS 15454 to increase reach distance if the link loss between nodes in a metro network is greater than 15 dB. The ONS 15216 EDFA1 can be used as a booster amplifier immediately following the transmitter, as an in-line amplifier at an intermediate site, or as a pre amplifier just before the receiver.
Chapter 1 Applications ONS 15216 EDFA1 Operation • Low-noise figure of < 6.0 dB Constant Gain Mode Constant amplification per wavelength is important for bandwidth-on-demand wavelength services. As wavelengths are added/dropped from an optical fiber, small variations in gain between channels in a span can cause large variations in the power difference between channels at the receivers.
Chapter 1 Applications ONS 15216 EDFA1 Operation Low Noise Noise increases whenever a gain occurs in an optical system. The predominant source of noise in EDFAs is Amplified Spontaneous Emission (ASE). The ONS 15216 EDFA1 has a low-noise figure of < 6.0 dB.
C H A P T E R 2 Technical Specifications This chapter discusses the technical specifications of the ONS 15216 EDFA1. See Chapter 3, “Installation” to set up and install the ONS 15216 EDFA1. See Chapter 4, “Provisioning and Monitoring” for information about a local serial port or remote connection. ONS 15216 EDFA1 Optical Specifications Table 2-1 lists the ONS 15216 optical specifications.
Chapter 2 Technical Specifications ONS 15216 EDFA1 Optical Specifications Table 2-1 ONS 15216 Optical Specifications (continued) Requirement Specifications Backward amplified spontaneous emission (ASE) power < -20 dBm Polarization Sensitivity <0.5 dB Automatic Gain Control (AGC) The ONS 15216 EDFA1 contains active-gain block with automatic-gain control loop to minimize the effects of output power variations per wavelength when adding/deleting wavelengths on the same DWDM ring.

The LED and alarm will automatically reset when the condition clears (see the “Alarm Contact Closures” section on page 4-8 for additional alarm contact closure information).
C H A P T E R 3 Installation This chapter discusses the ONS 15216 EDFA1 installation procedure, which includes power installation, optical cabling, alarm contacts, and installation commands. The ONS 15216 EDFA1 is logically divided into the following three sections: • Power section (-48V A, RET A, -48V A, RET B, and chassis ground) • Optical section (fiber input and output ports) • Communication section (RS-232 and Alarm Out) Each section (Figure 3-1) has an installation procedure in this chapter.
Chapter 3 Installation Optical Connections Procedure: Install the ONS 15216 in a Rack Step 1 Mount the ONS 15216 EDFA1 in the rack (19” and 23” reversible ears). Empty rack space is not required above or below the EDFA. Step 2 Connect the –48VDC cable to the office fuse panel. Note that 1.0A fusing is required and that 18AWG stranded wire or larger must be used. Connect wire lugs as appropriate to ends of wire (not provided).

C H A P T E R 4 Provisioning and Monitoring Each ONS 15216 EDFA1 is equipped with a microcontroller that allows you to provision and monitor several operating parameters. The microcontroller generates an alarm in event of failure. For example, if the performance of one of several operating parameters is out of range, an alarm is generated. Alarms are recorded and stored in the microcontroller’s memory and can be retrieved for review.

Chapter 5 Command Line Reference Maintenance Commands Explanation: Enter the LOAD START command to download new firmware. During the download process, feedback consisting of an increasing page count appears every second on the terminal screen (Example 5-19). Each page represents one loaded 128 byte flash page; there are two cyclic redundancy checks (CRCs)at the end of the load procedure. For a successful load, the CRC will match the Cisco-provided CRC (Cisco provides the CRC with its firmware upgrade).
Chapter 5 Command Line Reference Maintenance Commands SETADDR Command: SETADDR Syntax: SETADDR xx, where xx is decimal number Password: N/A Configuration: Yes Brief Description: Sets the address of the ONS 15216 EDFA1. This command enables a unique address to be assigned to each EDFA in systems where two or more ONS 15216 EDFA1s are used within one networking platform. Explanation: Enter SETADDR to assign an address to the EDFA module (Example 5-21).
Chapter 5 Command Line Reference Maintenance Commands Example 5-22 SRESET Command: 0-0>SRESET LD 1: Temp Compensated LD 2: Temp Compensated Caution Only use this command if the EDFA has entered an inconsistent state. After bootup, the current control mode of the EDFA is broadcast. In Example 5-22, the EDFA has the temperature-compensated constant gain mode as the default mode of operation. Note Alarms are not valid during the booting period (12 seconds). This command does not affect service.

C H A P T E R 6 Troubleshooting This chapter discusses basic fault investigation and diagnosis (troubleshooting) procedures for the ONS 15216 EDFA1.
Chapter 6 Troubleshooting Basic Diagnosis Basic Diagnosis When a problem occurs over the network, the following three basic diagnostic procedures are designed to help you determine if the ONS 15216 EDFA1 is the source of the problem. If the ONS 15216 EDFA1 is the source of the problem, follow the directions in the “Troubleshooting Commands” section on page 6-3 to clear the alarms and if necessary reprovision the ONS 15216 EDFA1 for proper operation.
Chapter 6 Troubleshooting Troubleshooting Commands Troubleshooting Commands Use the following troubleshooting commands to review alarms and the overall status of the ONS 15216 EDFA1 and, if necessary, to reprovision the amplifier. For additional detailed information regarding each of the following commands, see Chapter 5, “Command Line Reference.
Chapter 6 Troubleshooting Troubleshooting Commands CTMP 0-0> Major xxxxx yyy Case temp out-of-range The ALARM C command cleas the alarm after you determine and correct the problem, or you can use it to test a solution to a problem with the ONS 15216 EDFA1. Clearing active alarms resets alarm-monitoring circuitry within the ONS 15216 EDFA1 and is useful in verifying whether alarm conditions are present. Alarm Enable/Disable Commands Use the ALMDSBL command to disable a specific alarm.
Chapter 6 Troubleshooting Technical Support See SET_LOSTH, page 5-16 for additional information about this command.
