The Olson Technology, Inc. Model OTEA-CM Series 1550nm Erbium Doped Fiber Amplifier (EDFA) is a rackmount EDFA
package providing up to 20 optical outputs at +18, +20 & +21dBm, and is optimized to work with Direct Modulation
1550nm transmitters. 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 multichannel L-Band video.

The Model OTEA-CM 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 Super
Mod (Direct Mod) 1550nm transmitter, such as Olson's Model OT-1000-HH, can cost effectively replace large quantities of
standard 1310nm DFB transmitters without compromising system performance.

This rugged, low-profile, high-efficiency EDFA design provides eight (8) to 20 optical outputs in the 2RU package over a
wide operating temperature range, with low power consumption. The Model OTEA-CM Series also incorporates μP-con-
trolled 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 LaserLite Model OTEA-CM Series Erbium Doped Fiber Amplifier is the perfect companion to Olson’s LaserPlus,
LaserLite and SATELLitePlus families of 1550nm 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 up to 20 optical out­puts at +18, +20 & +21dBm each

• Optimized for use with Olson’s SuperMod (DirectMod)
1550nm transmitters.

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

• Takes direct input from a 1550nm Direct Mod transmit­ter without an intermediate driver

• Coolerless pump lasers reduce overall power con­sumption and increase reliablity

• Low optical input level requirements with excellent low
noise performance at high output

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

• Powering options for 110/220 Volts AC and -48 Volts
DC
