TA16-Type 2.5 Gbits/s Transponder with
16-Channel 155 Mbits/s Multiplexer/Demulitplexer
In the receive direction, the transponder module
receives a 2488.32 Mbits/s optical signal and converts
it to an electrical signal, extracts a clock signal, and
then demultiplexes the data into sixteen 155 Mbits/s
differential LVPECL data signals. The optical receiver is
available with either a PIN photodetector or with an
APD photodetector. The receiver operates over the
wavelength range of 1.1 µm to 1.6 µm and is fully com-
pliant to SONET/SDH OC-48/STM-16 physical layer
specifications as shown in Table 5, Optical Characteris-
tics.
Description
(continued)
The optical transmitter is available with either a 1.31 µm
Fabry-Perot laser for short-reach applications or
1.31 µm and 1.55 µm DFB lasers for intermediate- to
long-reach applications. The optical output signal is
SONET and ITU compliant for OC-48/STM-16 applica-
tions as shown in Table 4, Optical Characteristics.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect reliability.
