COAT optical amplifier card as part of CATS product family, is a
smart and plug-in card for CATS1000/3000, max output is able
to be 20dBm. The amplifier can be custom built to meet the
specific requirement, for single wavelength or multi-wave (WDM)
applications.Via CATS system controller card, COAT can be managed
by GUI based network management, command line interface(CCLI)
and SNMP. also via serial port COAT card can be managed locally.
Application Example - Fiber Extension
Combining COAT and other line cards, CATS provides a simple and
elegant soution for fiber extension, including for 1300 nm client
signals. As illustrated below, using CATS 1000, a 1300 nm signal can
be converted to 1550 nm wavelength using CLCT (up to 4G) or CLXT
(10G), then fed to COAT. COAT boosts the output to 13 or 17 dBm,
allowing a long distance transmission of up to 180 km at 2.5G (45
dB loss budget). For 10G signal, dispersion compensation must be
taken into account for transmission distance beyond 80 km. Contact
Dowslake for detailed 10G fiber extension solutions..

Note:
1) Customer specified output power shall be less or equal than the above specification.
2) Gain for single channel amplifier is used as reference only for optimization purpose.
Customer can set gain within the amplifier control limit, taking into account gain and noise
figure trade-offs.
