THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

FINAL DRAFT - CISCO CONFIDENTIAL

Applications

This manual describes how to install and operate the Cisco Optical Network System (ONS) 15216 Erbium-Doped Fiber Amplifier 2 (EDFA2). The ONS 15216 EDFA2 is an optical amplifier that enables the migration to next-generation all-optical networks. It features bandwidth-on-demand and wavelength protection switching that extend dense wavelength division multiplexing (DWDM) links by hundreds of kilometers.

With the ONS 15216 EDFA2, optical signals from a span in a DWDM network can be added or dropped without negatively affecting (degrading) other optical signals on the same span.

1.1 Bandwidth On Demand

The ONS 15216 EDFA2 is a technology for bandwidth-on-demand wavelength services. Depending on the settings and the input power, every wavelength in a ONS 15216 EDFA2 is guaranteed to be amplified by 13 to 22 dB. With the ONS 15216 EDFA2’s gain control technology, amplification for each wavelength remains constant at all times as wavelengths are added or dropped from an optical fiber. As long as the total (composite) input power of all wavelengths is between 4 dBm and –27 dBm, any number of wavelengths can be amplified.

CHAPTER

1.2 Wavelength Protection Switching

The ONS 15216 EDFA2 uses wavelength protection switching to restore wavelengths that are lost in the event of a fiber cut or other loss of signal. Figure 1-1 on page 1-2 shows an example of wavelength protection switching. In this example, two wavelengths are routed clockwise around a metro ring, and two wavelengths are routed counter-clockwise around the same ring. Of the two counter-clockwise wavelengths, only one transits the span linking locations D and C. If a fiber cut occurred on this span, the affected wavelength could be restored by rerouting it (clockwise) around the ring to location D. Wavelength protection switching minimizes the amount of bandwidth allocated for restoration because only the affected wavelength is restored, not the entire fiber.

Chapter 1 Applications

FINAL DRAFT - CISCO CONFIDENTIAL

The ONS 15216 EDFA2 has the following key features:

• Adjustable constant gain of 13 to 22 dB

• Gain flattening < 2 dB (peak to valley)

• Transient suppression

• Low noise figure of < 7 dB at –5 dBm input

• Simple Network Management Protocol (SNMP) MIBs

• Transaction Language 1 (TL1)

1.3.1 Constant Gain

Constant amplification (gain) per wavelength is important for ensuring that variations in power between channels at the receivers is minimized. 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. The ONS 15216 EDFA2 enables bandwidth-on-demand services by guaranteeing that every wavelength is amplified by a value that can be set between 13 and 22 dB, no matter how many wavelengths are being amplified.

Constant gain is achieved using an automatic control circuit that adjusts pump power when changes in input power are detected. The ONS 15216 EDFA2 operates in Constant Gain Temperature Compensated mode by default, but since there may be applications where other operating modes may be required, the ONS 15216 EDFA2 can be set to operate in any one the following pump control modes:

Key Features

• Constant Gain Temperature Compensated mode

• Constant Output Power mode

• Constant Pump Current mode

• Constant Pump Power mode

1.3.2 Gain Flattening

Figure 1-3 illustrates the effect of the gain flattening filter in the ONS 15216 EDFA2. Fiber (a) in the

figure shows a set of channels with equal powers being input to a cascaded network of amplifiers that produce vastly different power levels and optical signal-to-noise ratios (OSNR) at the output. In contrast, fiber (b) shows how the EDFAs effectively reduce this effect by introducing a gain flattening filter within each amplifier.

1.3.3 Transient Suppression

Transients in the performance of optical amplifiers are inevitable whenever the number of signals, or the relative power of signals, changes. The ONS 15216 EDFA2 uses transient suppression to reduce the amount of time required by an amplifier to recover from a change. This indicates the suitability of the amplifier for add/drop applications like those described earlier.

1.3.4 Low Noise

Whenever there is gain in an optical system, noise also occurs. The predominant source of noise in EDFAs is amplified spontaneous emission (ASE). The ONS 15216 EDFA2 has a low noise figure of less than 7 dB at –5 dBm input.

1.3.5 SNMP MIBs

The ONS 15216 EDFA2 SNMP MIBs contain definitions of management information that allows network systems to be remotely monitored, configured, and controlled.

1.3.6 TL1

The ONS 15216 EDFA2 has a TL1 interface available to the network operator and craftsperson.

Technical Specifications

This chapter discusses the technical specifications for the Cisco ONS 15216 EDFA2.

2.1 Optical Specifications

ONS 15216 EDFA2 optical specifications are listed and described in Tabl e 2-1.

Table 2-1 ONS 15216 EDFA2 Optical Specifications

Requirement Specification

Input signal wavelength 1530 nm to 1563 nm Input power (channel total) –27 dBm to 4 dBm (total all channels)

CHAPTER

See the “Maximum Input Power” section on page 2-2 and

“Channel Loading” section on page 2-2 for more information.

Note In the event of a fiber cut or loss of connection, and

there is no input power, the ONS 15216 EDFA2 has –3.5 dBm of output power. For additional safety information, see the “Safety Requirements” section on

page 3-3.

Mode of operation Unidirectional (two common fibers: one transmit, one receive) Maximum output power 17 ± 0.6 dBm Signal gain per channel 13 dB to 22 dB Channel gain deviation from setpoint ± 1.25 dB Gain flattened < 2 dB (peak to valley) Maximum noise figure < 7 dB at –5 dBm input power Polarization mode dispersion (PMD) < 0.6 ps Input/output optical return loss > 27 dB Backward ASE power –30 dBm maximum Polarization sensitivity < 0.5 dB Automatic gain control (AGC) The ONS 15216 EDFA2 contains an active gain block with an

automatic gain control loop to minimize the effects of output power variations per wavelength upon adding or deleting wavelengths on the same DWDM ring.

Optical Specifications

FINAL DRAFT - CISCO CONFIDENTIAL

2.1.1 Maximum Input Power

The ONS 15216 EDFA2 operates at a gain setting between 13 and 22 dB. Each gain setting has a maximum input power. The maximum input power is defined as 17 dBm (the maximum output power) minus the gain setting. For example, at a gain setting of 22 dB, the maximum input power is –5 dBm. At a gain setting of 13 dB, the maximum input power is 4 dBm. Prolonged operation beyond the maximum input power can shorten the life of the ONS 15216 EDFA2.

External optical attenuators are required to reduce the total input power to less than or equal to 4 dBm.

2.1.2 Channel Loading

You can ensure a smooth upgrade path from a single channel to the maximum numbers of channels with a minimum disruption of service if the per-channel power of the single channel is properly set from the start. The per-channel power should be set so that at full channel loading, the total input power is less than the maximum power indicated in Table 2- 2. For example, if the maximum number of channels at full loading is 18 and the gain is set to 22 dB, the maximum per channel power is –17.6 dBm.

Use Tabl e 2-2 to calculate per-channel power as a function of the maximum total number of channels at full loading. Contact Cisco TAC with any questions or concerns regarding maximum input power or setting the upgrade path.
