EMCORE’s Medallion 8000 is a directly-modulated DWDM optical transmitter specifically
designed for wideband applications that require both CATV and DBS signals to be
transmitted over up to
a
30 km length of fiber. This facilitates networks designs that use a
single transmitter to carry multiple signals.
Applications
High Power Distribution Networks
Redundant Ring Architectures
FTTx Networks
RFOG Applications
SAT-IF Transport
The Medallion 8000 supports full 79-channel NTSC analog signal and/or a combination of
QAM, DBS with reduced channel analog CATV. The Medallion 8000 can be selected as a
fixed fiber length option to support a fixed length from 0 – 10 km, 5 – 15 km, 10 – 20 km
and 15 – 25 km with 18 dBm SBS suppression maximum, or it can be ordered as a fiber
length selectable option. This option allows the user to set the Medallion 8000 for best
optimized CSO at any fiber length from 0 – 30 km with 1 km increments. At the selected
fiber length, the unit can perform within specification with a fiber length of ± 3 km. The
selectable fiber length option has a maximum SBS suppression of 20 dBm.
The Medallion 8000 family of transmitter products is designed to support various CATV
transmitter applications with a common platform. A 75 CATV RF video input supports
frequencies up to 1002 MHz. Integrated within the transmitter design are EMCORE’S low
chirp control, noise suppression circuitry, and patented predistortion technology to provide
outstanding performance with any of EMCORE’S wide range of cooled broadband lasers. A
second 75 RF input supports frequencies up to 2700 MHz for FTTP, SAT-IF, and
wireless applications.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those
given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can
adversely affect device reliability.

RF Characteristic
The following specifications are reference at 25°C. The CATV test receiver is the EMCORE receiver, model 7820A, with responsivity of
0.95 A/W (at 1550 nm). Test fiber is single mode, Corning SMF-28 (or equivalent) with 0.25 dB/km maximum loss (at 1550 nm). In order
to prevent reflection-induced distortion, the transmitter subassembly must be connected to an optical cable with discrete reflections < -55
dB and distributed reflections < -30 dB.
