High-speed data communications
The TA16 transponder performs the parallel-to-serialto-
optical transport and optical transport-to-serial-toparallel
function of the SONET/SDH protocol. The
TA16 transmitter performs the bit serialization and
optical transmission of SONET/SDH OC-48/STM-16
data that has been formatted into standard SONET/
SDH compliant, 16-bit parallel format. The TA16
receiver performs the optical-to-electrical conversion
function and is then able to detect frame and byte
boundaries and demultiplex the serial data into 16-bit
Note: The TA16 transponder does not perform bytelevel
Figure 1 shows a simplified block diagram of the
module designed to provide a SONET or SDH compliant
electro-optical interface between the SONET/
SDH photonic physical layer and the electrical section
layer. The module contains a 2.5 Gbits/s optical
transmitter and a 2.5 Gbits/s optical receiver in the
same physical package along with the electronics
necessary to multiplex and demultiplex sixteen
155 Mbits/s electrical channels. Clock synthesis and
clock recovery circuits are also included within the
In the transmit direction, the transponder module
multiplexes sixteen 155 Mbits/s LVPECL electrical
data signals into an optical signal at 2488.32 Mbits/s
for launching into optical fiber. An internal 2.488 GHz
reference oscillator is phase-locked to an external
