Installing the Cisco ONS 15216-MD-40-ODD and 15216-MD-40-EVEN Mux/Demux Patch Panels
Introduction
This document explains how to install and operate the Cisco ONS 15216 100 GHz 40-channel mux/demux patch panel.
The Cisco ONS 15216 40-channel mux/demux patch panel is a new ONS 15216 FlexLayer unit that allows 40-channels of ITU wavelengths to be placed onto a single fiber, and removes 40-channels of ITU wavelengths from a single fiber.
The ONS 15216 40-channel mux/demux patch panel can be odd or even patch panels:
•
15216-MD-40-ODD=: 40-channels spaced at 100 GHz on the Odd ITU grid
•
The only difference between the 15216-MD-40-ODD and 15216-MD-40-EVEN is the operating 100 GHz ITU grid. See "Channel Wavelength Allocation" section for C-band channel wavelength plan for the odd and even patch panels.
The patch panel can combine 40-channels of ITU wavelengths spaced at 100 GHz to a denser DWDM signal and separate the combined signal to 40-channels of ITU wavelengths spaced at 100 GHz. To increase the network capacity, the patch panel is plugged with an interleaver and deinterleaver module and is used along with another patch panel of a different grid. The interleaver module combines the signals from the 15216-MD-40-ODD and 15216-MD-40-EVEN patch panels spaced at 100 GHz to a denser DWDM signal spaced at 50 GHz and the deinterleaver module splits the combined signal (80 channel signal) to the 15216-MD-40-ODD and 15216-MD-40-EVEN patch panels in the opposite direction.
For installing the interleaver and deinterleaver module, refer to the "Installing Cisco ONS 15216-MD-ID-50 Optical Interleaver and Deinterleaver Pluggable" guide.
Safety Information
Before you install, operate, or service the Cisco ONS 15216 100 GHz 40-channel mux/demux odd and even patch panels, you must read the Regulatory Compliance and Safety Information for Cisco Optical Transport Products document for important safety information and warning translations.
The Cisco ONS 15216-MD-40-ODD and Cisco ONS 15216-MD-40-EVEN patch panels are compliant with the GR 1089, UL60950 /CSA 22.2 No. 60950-00, and IEC 60950 standards.
Laser Radiation Emission Restrictions
The Class 1M Laser safety and warning label is affixed to the Cisco ONS 15216-MD-40-ODD and Cisco ONS 15216-MD-40-EVEN patch panels and indicates that the product should never be used or installed in an optical network with emissions higher than Class 1M.
WarningLaser Safety During Operation
WarningElectrical Safety
The Cisco ONS 15216-MD-40-ODD and Cisco ONS 15216-MD-40-EVEN patch panels are optically and electrically passive and require no electrical connections. No electrostatic discharge (ESD) or other electrical safety considerations apply.
Product Description
The Cisco ONS 15216 40-channel mux/demux patch panel is a new ONS 15216 FlexLayer unit that allows 40-channels of ITU wavelengths to be placed onto a single fiber, and removes 40-channels of ITU wavelengths from a single fiber.
The patch panel works with 100 GHz WXC cards. When the patch panel works with 50 GHz WXC cards, the patch panel must be used with a pluggable interleaver and deinterleaver module along with another patch panel of a different grid.
The patch panel can be used in:
•
•

Features
The patch panel provides signal multiplexing and demultiplexing in 100 GHz channel spacing DWDM systems. It is optically and electrically passive and requires no temperature control. It uses fused fiber coupler technologies and a birefringent crystal technology platform. The ultra-low dispersion of the patch panel coupled with the wide bandwidth reduces the concerns of dispersion accumulation and bandwidth narrowing, making the patch panel ideal for Multi-OADM Metro ring or mesh-based architectures.
Some of the operating features of the patch panel include:
•

Functional Description
The functional unit of the ONS 15216 odd and even patch panel is the passive A-Thermal AWG (arrayed waveguide grating) optical module. The AWG optical module comprises of the mux and demux module as shown in Figure 1.
Figure 1 Mux and Demux AWG Modules
The multiplexer (mux) module combines signals from Chi-RX ports (40-channels) into the aggregated COM-TX port. An integrated tap-coupler combines the aggregated signals with the additional external sources injected at AUX-MUX port. An integrated tap-coupler splits 1% of the aggregated signals towards MON-MUX port that is used for monitoring purpose.
The demultiplexer (DMX) module separates the aggregated signals into individual Chi-TX ports. An integrated tap-coupler splits 1% of the aggregated signals coming from COM-RX port towards MON-DMX port that is used for monitoring purpose.

Fiber-Optic Connector Cleaning and Maintenance
Connector cleaning is required to maintain the performance of fiber-optic circuits. It is important that both the LC/UPC connector at the end of the fiber-optic cable and the mating bulkhead adapter on the front panel of the patch panel are clean before the connection is made.
WarningThe following warning applies to disposal of chemicals and other materials used to clean connectors and adapters:

Note
Customer Supplied Cleaning Materials
The Type A fiber optic connector cleaners (for example, CLETOP reel) are recommended to clean the cable connectors, but are not supplied with the patch panel.
When cleaning a paired cable connector (bulkhead mating adapter), always clean the mating adapter first.
If properly maintained (only used with clean, defect-free fiber connectors and capped when not in use), the mating adapter would not require cleaning. However, if you suspect the adapter is dirty, clean it by using the CLETOP stick swab.

Mounting Cable Guide
This section contains figures that indicate the position of the cable guide for various rack configurations of the patch panel.
Diagram 1 in Figure 12 indicates mounting cable guides for a single drawer configuration when fiber routes upward. 19-inch (482.6-mm) rack is shown for reference.
Diagram 2 in Figure 12 indicates mounting cable guides when fiber routes upward. When all fibers and USB cables come out from the same side, and space is available on the frame to mount the cable guide above the drawer, the cable guide must be positioned as shown in Figure 12. Single drawer configuration is shown for reference. 19 inch rack is shown for reference.
Diagram 3 in Figure 12 indicates mounting cable guides when fiber routes downward. Each drawer will have a cable guide mounted when fiber routes downward as shown. 19-inch (482.6-mm) rack is shown for reference.
Figure 12 Single Drawer Configuration
Diagram 1 in Figure 13 indicates mounting cable guides for a two drawer configuration, when fiber routes upward from both drawers. 19-inch (482.6-mm) rack is shown for reference.
Diagram 2 in Figure 13 indicates mounting cable guides when fiber routes upward. This is only used for 5", 6", and 6.5" recess mounting. Use a 40 mm recess on the drawer to mount the cable guide. 23-inch (584.2-mm) rack is shown for reference.
Figure 13 Two Drawer Configuration
Fiber Protection
This section contains figures that indicate cable guide protection for fibers routing upward and downward and also the protection provided by velcro and cable tie.
Diagram 1 in Figure 14 shows the fiber protection for upper most drawer or in a single drawer configuration.
Diagram 2 in Figure 14 shows fiber protection for fibers routing downward.
Diagram 3 in Figure 14 shows fiber protection provided by the upper cable guide for fibers routing upward.
Figure 14 Fiber Protection
After the patch panel drawer is closed, velcro is wrapped around the fibers. When the fiber routes upward, the cable tie is tied around the fiber through the cable guide. When the fiber routes downward, no velcro or cable tie is needed.
Diagram 1 of Figure 15 shows velcro and cable guide tied for a single drawer configuration.
Diagram 2 of Figure 15 shows velcro and cable guide tied for a double drawer configuration.
Figure 15 Velcro and Cable Tie
Performance Monitoring
The patch panel uses Optical Test Access Port (TAP) devices to enable passive access and monitoring in the fiber-optic network. The TAPs enable network-based intrusion detection system sensors to operate efficiently without interruption. They send traffic data to a monitoring device by splitting the network signal, without introducing delay or changing the content or structure of the information contained in the packets. An OSA (Optical Spectrum Analyzer) or PM (Power Meter) can be used for optical power monitoring and optical analysis.
Table 3 shows the manufacturer-specified TAP split ratios for the TAP coupler optical power in the patch panel. The split ratio denotes the ratio of the TAP input signal to the output signal.
Table 3 Manufacturer-Specified TAP Split Ratio
