• The Cisco ONS 15216 DWDM system supports up to 32 wavelengths and offers transport flexibility with optical filtering, optical add/drop multiplexing (OADM), optical performance monitoring, and amplification.

• The Cisco ONS 15216 metro DWDM platform includes the following components chassis configurations:

• Cisco ONS 15216 DWDM Filter• Cisco ONS 15216 Optical Add/Drop Multiplexer (OADM)• Cisco ONS 15216 Erbium Doped Fiber Amplifier (EDFA)• Cisco ONS 15216 Optical Performance Monitor (OPM)• Cisco ONS 15216 Flex Layer• Cisco ONS 15216 System Dispersion Compensation Unit (DCU)• Cisco ONS 15216 Optical Supervisor Channel (OSC-1510)

Cisco ONS 15216 DWDM System Application

• The Cisco ONS 15216 can be configured differently based on various modules installed. In this ONS 15200 ring configuration example, wavelength channels exist between an ONS 15252 and one or several ONS 15201 through an ONS 15216 MUX/DEMUX (also known as a filter) and an ONS 15216 OADM. A device installed in the ONS 15252 exchanges data with an associated device installed in an ONS 15201 using one of the wavelength in the ONS 15216. Devices are connected to an ONS 15216 with SC connectors.

• The 1:x Splitter/x:1 Coupler (x being 2, 3, or 4), are completely passive components that can be used as splitters or couplers. These modules can be used to couple the composite outputs (ADD-COM-TX ports) of the Optical Add or Drop Flex Layer modules or split their input signal to the composite input (DROP-COM-RX) of the Optical Add or Drop Flex Layer modules.

• Figure 1, Figure 2 and Figure 3 show the unit block diagrams of the 1:2 Splitter/2:1 Coupler, 1:3 Splitter/3:1 Coupler, and the 1:4 Splitter/4:1 Coupler respectively. With reference to the Figure 1, Figure 2, and Figure 3, the signal flows from bottom to right when the component is used as a coupler and from right to bottom when the component is used as splitter.

• When the module is used as a coupler, the individual signals enter the card from the CPL-RX ports and are coupled together through a passive coupler to the CPL-TX port.

• When the module is used as a splitter, the composite signal enters the card from the SPL-RX port and is split through a passive splitter to individual signals to the SPL-TX ports.

Cisco ONS 15216 Flex Layer –Y-Cable Protection Flex Layer Modules

• The Y-cable protection module is a bidirectional module that is equipped with a passive splitter and passive coupler.

• The purpose of this module is to provide Y-Cable protection for transponder cards such as the ONS15454 multirate and 10G transponders. This allows a path for the working client transmit interface to connect to the network in the event the opposite interface in the protection pair should fail.

• There are two versions of this unit, one for multimode applications (CS-MM-Y) and one for single mode applications (CS-SM-Y).

• Figure 1 shows the unit block diagram of the Y-cable protection module.• When the module is used in the coupler direction, the individual signals enter the module

from the CPL-RX ports and pass through a passive coupler to the CPL-TX port. • When the module is used in the splitter direction, the signal enters the module from the

SPL-RX port and is split through a passive splitter to individual signals to the SPL-TX ports.

• Figure 2 show the physical appearance of the ONS15216 Y-Cable Protection Flex Layer Module.

• Figure 3 shows how the module front panel ports are mapped and labeled. The multimode unit is mapped and labeled the same as the single mode unit.

Cisco ONS 15216 Flex Layer –Four Channel VOA Flex Layer Module

• The four-channel Optical Variable Attenuator (VOA) module is a completely passive unidirectional component that allows equalizing the optical power of up to 4 channel groups.

• Figure 1 shows the physical appearance of the ONS15216 four channel VOA Flex Layer Module. VOA adjustment access is identified by VOA adjustment ports VOA 1 to 4 Adjust.

• Figure 2 shows the unit functional block diagram. The input signals always flow from the VOA#-RX ports to the VOA#-TX ports. The pound (#) in the previous name convention identifies the number of ports and is limited from 1 to 4. The input signals are attenuated by the manual adjustment of the VOAs that are placed between the input and output ports.

• Figure 3 shows how the module front panel ports are mapped and labeled. The VOA#-TX ports are mapped with the even ports from 2 to 8 and the VOA#-RX ports are mapped with the odd ports from 1 to 7.

OSC Add/Drop ports: West and East directionsMonitor ports: West and East directionsSC-type connectors

• The Cisco ONS 15216 Optical Supervisory Channel (OSC) 1510 allows communication to any site without the need for a functioning OADM, EDFA, or mux/demux at that site. This type of communication is established by removing the OSC signal from the composite DWDM signal before the composite signal passes through any other ONS 15216 equipment. The OSC signal is then added into the composite signal enabling Ethernet connectivity from the network operations center (NOC) to each device on the ring.

• The ONS 15216 OSC-1510 is a 1-RU 19- or 23-inch rack-mounted shelf assembly. To help with port identification and cabling, there is a retractable tray located under the front panel that contains a port layout diagram.

• The front panel of the OSC-1510 is shown in Figure 1. The OSC Add/Drop ports are used to pass through the OSC signals in West and East directions. Monitor ports in West and East directions are also provided so a user can check for the presence of the OSC channel in the composite DWDM signal. The ONS 15216 OSC-1510 uses SC-type optical connectors.
