The Olson Technology, Inc. Model OTEA-CL series 1550nm Erbium Doped Fiber Amplifier (EDFA) is a rackmount 1RU or
2RU EDFA package providing 4 to 24 optical outputs at +18 to +22dBm each. It is engineered to meet the requirements
for a high-density solution for the very large-scale distribution of broadband CATV video and/or wideband multi-channel L­Band video. The OTEA-CL series has a number of versatile features. For instance, the optical output power can be
adjusted from 0 to 3dB below the rated power by the user via the RS-232 serial port.

The Model OTEA-CL-Series eliminates the traditional requirement of converting the optical signal to 1310nm for “last
mile” distribution, facilitating the design of robust end-to-end optical transport networks directly from the head-end to large
numbers of remote node or premise locations without O-E-O conversions. The combination of this EDFA and a 1550nm
transmitter, such as an externally modulated (EM) 1550nm transmitter (i.e. the Olson Model OTOT-EM55X or XL) or
directly modulated (DM) 1550nm transmitter (i.e. the Olson Model OTOT-870-FF or FQ) can costeffectively replace large
quantities of standard 1310nm DFB transmitters without compromising system performance.

This rugged, low-profile, high-efficiency EDFA design provides up to eight optical outputs in the 1RU chassis and 24 opti­cal outputs in the 2RU package over a wide operating temperature range, with low power consumption. The Model
OTEA-CL-Series also incorporates P-controlled electrical control circuitry, and is stabilized with APC. This includes photo­diodes for monitoring the optical input and output power through tap couplers. The pump laser diode input current is
determined by a feedback circuit in order to minimize the difference between the detected output power level and preset
output power level. The 1RU package can deliver a total of 800mW/+29dBm. The 2RU package is used for total power
levels above 800mW/+29dBm.

The LaserLite Model OTEA-CL-Series erbium doped fiber amplifier is the perfect companion to Olson’s LaserPlus,
LaserLite and SATELLitePlus families of 1550nm EM and DM transmitters and the MetroNode, PremiseNode and
SATELLitePlus families of receiver/nodes. It is also designed to operate seamlessly with optical transmitters, receivers
and nodes from most leading manufacturers.

Features

• Single channel booster EDFA with 4 to 24 optical out­puts @+18 to +22dBm each

• Specifically for distribution of 1550nm video/data in
HFC, PON or FTTH systems

• Takes direct input from a 1550nm transmitter (EM or
DM) without an intermediate driver

• Coolerless pump lasers reduce overall power con­sumption and increase reliablity

• Optical output can be adjusted up to 3dB below rated
power via RS-232 port

• Front-Panel and RS-232 serial interface for monitoring
and control of EDFA
