INTRODUCTION
The HD 6-Pack series of fiber optic transmitters and receivers makes possible the media
conversion and combining of up to 6, 12, or 18 digital signals onto one fiber (HD6000-ONE,
HD12000-ONE or HD18000-ONE, respectively) using CWDM techniques or onto 6,12, or 18
fibers (HD6000, HD12000 or HD18000) for transport up to 20km The units accept and output
75 ohm digital signals with data rates ranging from 125MBPS up to 2970 MBPS. Although
designed for SMPTE 424,292, or 259 SDI and DVB-ASI, the HDx000/x000-ONE can be used
with other protocols within this range. Each of the 6,12 or 18 channels has a reclocker that is
bypassable for non-SMPTE signals, and can support up to 120m of coax cable using its built
in equalizer.
It is also possible, upon special order, to have a mixture of transmit and receive channels at
each end to support bidirectionality. For example in a HD6000 you could have 3 transmit and
3 receive channels at each end, or any other combination.
Applications include transmission links for high definition or digital television studio to
transmitter, studio-to-studio, or any other similar long-range situations. It can also combine
and transport the outputs of other Multidyne products that fall within its 19 to 2970 MBPS
operating range..
FEATURES and OPERATION
The following discussion assumes that we have a HD6000 standard configuration consisting
of 6 transmit channels at one end and 6 receive at the other end. The HD12000 and 18000
are just 2 or 3 HD6000s in one case with common power and common optical I/O for the
‘ONE versions.
Each FTX channel consists of a cable receiver and a reclocker. The cable receiver can EQ
up to 120m of cable at 3 GBPS. In the case of the HD6000-ONE, each channel has a CWDM
SFP transmitter. In the HD6000, each has a standard 1310 nm SFP transmitter. The
reclocking function can be bypassed. The HD6000-ONE also contains a CWDM cassette to
combine the 6 CWDM channels onto a single fiber. The HD6000 does not have the cassette
as it will use 6 individual fibers.
Each HD6000/6000-ONE FRX channel consists of a standard SFP receiver that can accept
wavelengths of 1100 to 1600 nm, a bypassable reclocker, and a cable driver. In the case of
the HD6000-ONE, a CWDM cassette is included to route
the single fiber’s 6 wavelengths to
the SFP optical inputs of the 6 channels. The HD6000 has no cassette and its SFPs receive
their inputs directly from 6 individual fibers.
It is possible to order the HD6000/6000-ONE with a mixture of transmit and receive channels
at each end to support bidirectionality. For example on end could have 4 TX and 2 RX and
the other 4 RX and 2 TX, or any other combination.
The following discussion of the front and rear panels assumes the 6 channel versions. The
12 or 18 channel versions would have the HD6000 panel features replicated into 2 or 3
groups of 6 channels each In order to accommodate 12 or 18 channels instead of just 6.
