Product overview
The flashlink
®
HD-EO is a multi bit-rate electrical to optical converter module
providing high performance media conversion for various signal formats from
19.4Mbps up to 1485Mbps. This state of the art unit offers Fabry-Perot (F-P)
or “Distributed Feedback” (DFB) laser technology with long wavelength on
single mode fiber. Unmatched signal accuracy, even in critical applications
with pathological signal patterns makes the HD-EO the first choice for all
optical transport demands.
The HD-EO can transport all HD and SD signal formats in addition to DVB-ASI
and SMPTE 310. It can also perform signal reclocking, which is selectable on
application. The optical output comes with a sophisticated 1310nm F-P laser
covering the demands of short and medium haul applications, optionally a
DFB laser for medium and long haul applications, with 16 CWDM
wavelengths available. The open system platform of Network Electronics
flashlink
®
system allows easy interoperability with third party fiber optical
systems.
The electrical input(s) are equipped with a multi rate cable equaliser(s)
providing an equalisation of typically 100m of high quality coax cable at
1485Mbps. A distribution amplifier with 2 outputs reduces the need for
additional DA’s (on HW version 1, only one can be used for DVB-ASI).
Optionally, a built-in change-over can switch to the standby input if the main
input experiences a loss of signal (version 2 hardware only).
