Optical Clock Multipliers


 


PriTel’s OCM Series of Optical Clock Multipliers
are designed for applications in high-capacity
fiberoptic communications research at 1550 nm.
 Based on OTDM (optical time-delay multiplexing),
these passive multiplexers increase the pulse
rate of input signals by factors of 2, 4, 8, or 16 for
RZ input-pulse frequencies of 10 GHz to 40 GHz.

Output frequencies up to 320 GHz have
been achieved with PriTel's OCM.  For
example, see S. Nakamura, Y. Ueno,
and K. Tajima, "Error-free all-optical
demultiplexing at 336 GB/s with a hybrid-
Integrated Symmetric-Mach-Zehnder
Switch," Optical Fiber Communication
Conference (OFC 2002), March 17-22,
2002, Anaheim, Postdeadline Paper FD3.

PriTel's OCM is often used in Bit Error Rate
Testing of 27-1 bits at 40 GHz with a 10 GHz input.
For other bit patterns and input repetition rates,
the reconfigurable version of the OCM is
available.

Model OCM-4
RF Spectrum of Output Signal
Input = 10 GHz, Output = 40 GHz




In OTDM applications, it is important to suppress the
input repetition rate in the output signal.  PriTel's OCM
maintains an output-to-input signal ratio >35 dB, as
shown in the RF spectrum on the left.  This high
performance is achieved through PriTel's design and
construction techniques.
