Elcom designs, manufactures and markets key microwave products, used in ultra-high-capacity fiber optic networks, typically for undersea cables with capacities of 10 Gbps to 40 Gbps, but increasingly with terrestrial lines as well. The modules employ a proprietary technology to generate phase-stable, low jitter clock signals. These features allow operation with minimal error seconds. We are able to customize a variety of other products for this market according to customer's needs, such as DRO based clock recovery modules. Highlights:

The
COS-192 clock oscillator is designed to meet the requirements of most
critical timing application such as SONET/SDH systems operating from 10
Gbit/s to 40 Gbit/s. Elcom COS-192 consumes less than 1 watt of DC power
(50% less than competing units). This low power dissipation significantly
improves unit MTBF due to lower junction temperature of active devices.
The fundamental bipolar oscillator design that is utilized in these units,
assures the lowest jitter and phase noise performance. Elcom's innovative
Zero Phase Hits Technology assures a stable signal over the lifetime of
the oscillator.
Elcom Technologies' Clock Translators employ proprietary technology to
ensure a phase stable output clock and a smooth transition between Master
and Slave operation. In the Slave mode the output frequency phase locks
to the input clock, while in the Master mode the output signal is derived
from an internally stable OCXO. The unit is designed for low power dissipation
thus decreasing semiconductors junction temperatures and improving system
reliability.
Elcom
technologies' miniature Variable Speed Clock Recovery Module (VSCR-192),
operate from 9.95 to 12.5 Gbps. The unit employs Elcom's proprietary low
phase noise VCO that spans the full frequency band and digital phase lock
loop, that enables reliable phase/frequency acquisition.
The
SCDR-192 clock and data recovery module is designed to meet the requirements
of the most critical applications, such as long haul SONET/SDH fiber optic
networks. Elcom's proprietary design emphasizes the high reliability and
low power consumption of this product series.
