35XX Series, 280 μs Max
Fiber Optic Delay Lines
DATASHEET | NOVEMBER 2013
MICROWAVE
The 35XX Series Fiber Optic Delay Lines deliver unmatched perfor-
mance for radar testing, signal processing, phased array antennas
and phase noise testing. When used in conjunction with either
the 5016A/B/C/D fiber optic transceiver, System 10000 rack-mount
transmitters and receivers, or EMCORE flange-mount transmitters
and receivers, these rugged devices eliminate many of the problems
that are inherent in alternative delay line technologies including acoustic wave
devices and coaxial delay lines.
EMCORE’s fiber optic delay lines provides bandwidth and insertion loss that are

essentially independent of delay and triple transit signals that are immeasurable.
In addition to enhancing electrical performance, the delay lines provide several
mechanical advantages. EMCORE’s technology takes advantage of the rigid, yet
flexible properties of fiber optic cable to provide repeatable enhanced phase and
group delay characteristics.
EMCORE’s 35XX Series Fiber Optic Delay Lines consist of three unique
versions:
355A - Flange-Mount
Features
Delays Up to 280 microseconds
356A/B - Double-Wide Plug-In, compatible with the System 10000 chassis
357A/B/C/D/E - Rack-Mount, which is integrated into the System 10000 chassis
The small size of these components allows for long delays in a compact package
with the superior temperature stability of fiber.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given
in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely
affect device reliability.
