Optical Switch Tray
OST
Optical Switch Tray
The Polatis OST family of products set the industry
benchmark for performance in a compact, fully non-blocking
optical switch.
The OST is an ideal platform for network-level switching,
given its ultra-low loss, fast switch speed, and high reliability
for fiber routing, IP over optical, and client-side switching.
The ability to manage bi-directional traffic
and switch dark fiber provides network operators
with an ideal tool for fiber-layer monitoring.
The OST also excels in test environments, providing
physical-layer connectivity for sharing of high value
equipment and for automation of test sequences in design,
verification, and manufacturing systems. Its instrument-
grade performance ensures the maximum signal fidelity,
with ultra-high stability and repeatability.
The OST is available in both symmetric (NxN) and
asymmetric (MxN) port configurations, provided in
a standard 19" rack mount enclosure.
DirectLight
®
Technology
All Polatis products are based on the patented DirectLight
beam-steering technology, setting the benchmark for
reliable, high performance switching.
Polatis also offers multimode OST and Reconfigurable single
mode OST products, as well as a range of optical switch
modules and standard backplane optical cards.

Ordering Information
The part numbering scheme for Polatis products is as
follows:
OST -
x
-
1-
All parameters are measured excluding connectors at 1550nm and 20°C with an unpolarized
source after thermal equalization unless stated.
1. Measured using a 3 patch-cord method as defined in TIA/EIA-526-14A
2. With APC connectors return loss >70dB without connectors
3. Switch will operate on dark fiber
The performance characteristics of the switch trays vary
according to the fiber count.
