Safety precautions
Please read the manual first before installing and using this product. The manufacturer is not responsible for any
equipment damage, personal injury, or property damage caused by improper operation.
The laser output is a high-power invisible laser. The laser radiation can seriously damage
your eyes or skin.
Avoid vibration and collision. The device contains precision optical components
that can be damaged.
Please handle carefully and ensure the device is properly grounded.
The device is sensitive to static electricity.
Do not open the device. If there are any issues contact a Technetix
representative immediately.
Special notice for the optical fibre interface:
1. The optical fibre interface must be clean.
2. When setting up the device insert the output fibre first, then insert the input fibre.
When removing optical cables, remove the input first and then the output cable.

1 Description of the high power EDFA-R
1.1 Overview
The EDFA-R occupies 1RU or 2RU in a 19" sub-rack. The key component of this product is a very reliable multimode
pump laser. A unique Automatic Power Control (APC) and Automatic Temperature Control (ATC) circuit ensures stable and
reliable output power. The unique optical circuit design ensures excellent optical performance.
The optical circuit is designed specifically for CATV systems. It features a low noise profile to ensure an excellent CNR
for analogue systems sensitive to noise. The device also has a high level of spectral flatness across the entire C-band to
ensure better CSO. The design includes dual hot-swappable redundant power supplies to reduce the MTBF.
The EDFA-R has an intelligent temperature control system that can reduce power consumption by up to 30%. When the
case temperature is over 45 degrees Celsius, a fan will start and continue to operate until the temperature is under 40
degrees Celsius. The technology ensures the thermal stability of the system and increase the fan’s lifespan.
It has an intelligent network management system. The device can be controlled through the Ethernet interface, the RS-485
interface, and RS-232 interface. In addition, it can be controlled through SNMP MIB to integrate it with a variety of network
management systems.
1.2 Features
■ Low noise profile: typically less than 4.5 dB (0 dBm input)
■ Extremely low CSO distortion: <-70 dBc
■ Dual power supplies supporting 220V mixed interpolation with 48V
■ High stability and reliability: MTBF 100,000 hours
■ Multiple management interfaces: Ethernet, RS-485, and RS-232
■ Supports Telnet and standard SNMP network management
■ High precision AGC/APC circuit: precision is ± 0.05 dB
■ Intelligent temperature control system: power consumption reduced by up to 30% compared to similar products
■ 1RU or 2RU in a 19” sub-rack
■ Bellcore GR-1312-CORE compatible
