the mains power without a protective ground conductor.
◦If this equipment is equipped with an external grounding terminal, attach one end of an 18-gauge
wire (or larger) to the grounding terminal; then, attach the other end of the wire to a ground, such as a
grounded equipment rack.
1.2 Installation Site
When selecting the installation site, comply with the following:
• Maintain a Protective Ground - The protective ground lead of the building’s electrical installation should comply with
national and local electrical and safety requirements.
• Environmental Condition - The installation site should be dry, clean, and ventilated. Do not use this equipment where
it could be at risk of contact with water. Ensure that this equipment is operated in an environment that meets the
requirements as stated in this equipment’s environmental specications.
1.3 Installation Requirements
WARNING: Allow only qualied service personnel to install this equipment. The installation must
conform to all local codes and regulations.
1.4 Equipment Placement
WARNING: Avoid personal injury and damage to this equipment. An unstable mounting surface
may cause this equipment to fall.
• Install this equipment in a restricted access location.
• Place this equipment close enough to a mains AC outlet to accommodate the length of this equipment’s power cord.
CHAPTER 1:
SAFETY
1-2 Chromadigm CHS/CHQ Transmitter – Quick Start Guide
• Route all power cords so that people cannot walk on, place objects on, or lean objects against them.
• Make sure the mounting surface or rack is stable and can support the size and weight of this equipment.
• Make sure that the rack is placed on a stable surface. If the rack has stabilizing devices, install these stabilizing
devices before mounting any equipment in the rack. The mounting surface or rack should be appropriately anchored
according to manufacturer’s specications.
• Ensure this equipment is securely fastened to the mounting surface or rack to protect against damage.
• This equipment has openings for ventilation to protect it from overheating. To ensure equipment reliability and safe
operation, do not block or cover any of the ventilation openings.
WARNING: Avoid personal injury and damage to this equipment. Mounting this equipment in the
rack should be such that a hazardous condition is not caused due to uneven mechanical loading.
CAUTION: Installation of this equipment in a rack should be such that the amount of airow
required for safe operation of this equipment is not compromised.
1.5 Power Connections
1.5.1 Connection to AC Power Source
IMPORTANT: If this equipment is a Class I equipment, it must be grounded.
• Connect this equipment only to the power sources that are identied on the equipment-rating label.
• Overcurrent protection breakers or fuses must be sized appropriately for the total current rating of the modules and
accessories contained within a system chassis or multiple chassis that are connected to a common mains circuit.
• This equipment may have two power sources. Be sure to disconnect all power sources before working on this
equipment.
• If this equipment does not have a main power switch, the power cord connector serves as the disconnect device.
1.5.2 Connection to -48 VDC Power Source
• Use at least #16 AWG wire for all DC power wiring.
• Overcurrent protection breakers or fuses must be sized appropriately for the total current rating of the modules and
accessories contained within a system chassis.
• Follow the recommended practices of the DC power system manufacturer.
CAUTION: Consider the connection of this equipment to the supply circuit and the effect that
overloading of circuits might have on overcurrent protection and supply wiring.
1.6 Fuse Replacement
To replace a fuse, comply with the following:
• Disconnect the power before changing fuses.
• Identify and clear the condition that caused the original fuse failure.
• Always use a fuse of the correct type and rating. The correct type and rating are indicated on this equipment.
1.7 Laser Safety
This equipment may be connected to an infrared laser source that transmits intensity-modulated light and emits invisible
radiation.
CHAPTER 1:
SAFETY
Chromadigm CHS/CHQ Transmitter – Quick Start Guide 1-3
WARNING: Avoid Personal Injury. The laser light source on this equipment or the ber cables
connected to this equipment emit invisible laser radiation. Avoid direct exposure to the laser light
source.
Viewing the laser output (if a transmitter) or ber cable with optical instruments may pose an eye
hazard.
This equipment may only be installed, operated and serviced by authorized personnel trained in
the safe handling and operation of ber optic cables and laser sources.
• Do not apply power to this equipment if the ber is unmated or unterminated.
• Do not look into an activated ber with optical instruments such as magniers, or microscopes.
1.8 Laser Power & Warning Labels
This equipment may contain or be connected to other equipment containing Class 1M laser sources. The following labels
adhered to each product will indicate the type of laser source utilized along with general laser radiation labels.

PRODUCT INTRODUCTION
2. Product Introduction
The Chromadigm CHS/CHQ transmitter is a full 1002 MHz RF spectrum transmitter with four ITU DWDM lasers multiplexed
onto a single optical output port in a 1RU chassis. The CHS/CHQ incorporates ATX’s Chromadigm chirp cancellation and
clipping mitigation technology, signicantly advancing the performance of analog optical DWDM systems. The technology
allows up to 44 consecutive, 100 GHz spaced ITU channels, while delivering exceptional MER and error-free, pre-FEC BER
performance. Being void of distance tuning provides the exibility to simply split the optical output into route diverse ber
rings without performance degradation or having to retune the transmitter when switched between different lengths of ber.
The CHS/CHQ transmitter with its innovative technology sets the performance standard in DWDM full band systems offering
a unique set of benets:
• Chirp cancellation for distance independent performance.
• Adaptive clipping mitigation for error-free QAM performance.
• High OMI for superior CNR/MER performance.
• Full utilization of the ITU DWDM spectrum.
• Extended reach to eliminate remote hubs.
• Four integrated DWDM transmitters multiplexed on a single output.
• Reduced network complexity for decreased operating expense.
• Drop-in upgrade for node segmentation and hub eliminations.
• Increased network reliability.
The Chromadigm CHS/CHQ is available with +6 dBm, +9 dBm or +12 dBm output power to support a wide variety of
applications. Integrated, optical express ports can be added for extracting return path wavelengths or multiplexing additional
forward path CHS/CHQ chassis together.
