Cisco NCS 1001 Overview
Cisco NCS 1001 (NCS1001-K9) is 1 RU chassis that addresses the growing bandwidth needs of data center
DWDM applications. It provides a DWDM line system that is optimized for data center environments and is
optimized for point-to-point applications at maximum capacity. NCS 1001 supports up to three optical modules.
The modules can be amplifiers or protection switching modules.
NCS 1001 has the following components:
•Removable control card
•Four removable fans
•Two removable 600W AC/DC or DC/DC power supply modules (PSU)
•Three slots for optical modules. Two Optical Amplifier Modules ( NCS1K-EDFA) and a Protection
Switching Module (NCS1K-PSM) can be inserted in these slots.
The optical modules can be inserted in slots 1 to 3 as shown in the following figure. The optical modules
can be inserted and removed from the slots while the system is operational. In amplified configuration,
the Optical Amplifier module can be inserted in any slot. In (section) protected configuration, the protect
Optical Amplifier module is inserted in slot 1, Protection Switching Module in slot 2, and working
Optical Amplifier module in slot 3.
Hardware Installation Guide for Cisco NCS 1001
1
Each optical module must be inserted in a slot only when the module in the adjacent slot is completely
inserted and seated or the adjacent slot is empty. If an optical module is inserted in a slot without seating
the adjacent module, the ejector might interfere with the adjacent module.
Caution
The empty slots must be inserted with the filler optical modules or filler PSUs as appropriate to guarantee
safety and system cooling compliance. See Figure 1: Cisco NCS 1001 Front View, on page 2 and Figure
3: Cisco NCS 1001 Rear View, on page 3 to identify the slots for optical modules and PSUs respectively.

Benefits
NCS 1001 provides the following benefits.
•Up to 23dBm output power to allow for +3dBm per channel fiber launch power and maximum optical
performance for high baud rate and higher order modulation format transponders.
•Switchable gain pre-amplifier up to 34db.
•Embedded Optical Channel Monitoring (OCM) module to monitor per channel power at all the input
and output ports.
•Integrated pluggable optics based OSC and OTDR support.
•OSC supports user data channel transport as well as remote node management.
•Supports 96 channels of C-Band in 1 RU.
•Supports flex grid on OCM module.

Optical Amplifier Module
The optical amplifier module (NCS1K-EDFA) has pre-amplifier and booster amplifier.
The optical amplifier module provides the following functionality.
•Preamplifier (LINE-RX to COM-TX) - Single preamplifier variant, with switchable gain ranges, according
to link loss:
◦Range # 1: 0 to 24 dB gain, Tilt control: 24 to 27 gain, with tilt uncontrolled
◦Range # 2: 20 to 34 dB gain, Tilt control: 34 to 37 dB gain, with tilt uncontrolled
◦23dBm output power @ COM-TX port
•Booster amplifier (COM-RX to LINE-TX) - True variable gain booster amplifier
◦Gain range: 1 to 20. 20 to 25 uncontrolled tilt.
◦23dBm output power @ LINE-TX port
•ADD/DROP OSC channel supports both 1510nm and 1610nm +/-10nm
•OCM assesses channel presence and Gain regulation and per channel power monitoring.

Protection Switching Module
The protection switching module (NCS1K-PSM) provides the following functionality.
•In TX section:
◦Splits input optical channels to both working and protection lines.
◦Forces the switch in the remote site by opening one of the two line paths (by putting the related
VOA in AVS).
•In RX section:
◦Selects the signals from working or protection line. Each line is monitored through a PD.

◦Balances the two line losses by changing the VOA attenuation value at the same time of the switch
change of state.
