CA16-Type 2.5 Gbits/s DWDM Transponder with
16-Channel 155 Mbits/s Multiplexer/Demultiplexer
Description
(continued)
Figure 1 shows a simplified block diagram of the CA16-
Type transponder. This device is a bidirectional module
designed to provide a SONET or SDH compliant elec-
tro-optical interface between the SONET/SDH photonic
physical layer and the electrical section layer. The mod-
ule contains a wavelength-tunable (two channels at
100 GHz) 2.5 Gbits/s optical transmitter and a
2.5 Gbits/s optical receiver in the same physical pack-
age along with the electronics necessary to multiplex
and demultiplex sixteen 155 Mbits/s electrical channels.
Clock synthesis, clock recovery, and SONET/SDH
frame detection circuits are also included within the
module.
In the transmit direction, the transponder module multi-
plexes sixteen 155 Mbits/s PECL electrical data signals
into an optical signal at 2488.32 Mbits/s for launching
into optical fiber. An internal 2.488 GHz reference oscil-
lator is phase-locked to an external 155.52 MHz data
timing reference.
The optical transmitter is available at any ITU grid
wavelength with a 1.55 μm cooled DFB laser for long-
reach applications. The optical output signal is SONET
and ITU compliant for OC-48/STM-16 applications as
shown in Table 4, OC-48/STM-16 Transmitter Optical
Characteristics.
In the receive direction, the transponder module
receives a 2488.32 Mbits/s optical signal and converts
it to an electrical signal, and then extracts a clock sig-
nal and demultiplexes the data into sixteen 155 Mbits/s
differential LVPECL data signals. When enabled, the
module can also detect SONET/SDH frame bound-
aries. The optical receiver is available with an APD
photodetector. The receiver operates over the wave-
length range of 1.1 μm to 1.6 μm and is fully compliant
to SONET/SDH OC-48/STM-16 physical layer specifi-
cations as shown in Table 5, OC-48/STM-16 Receiver
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.
