FM Video Fiber Optic Link, Single or Multimode
- Model 2768
The
Model 2768 FM Video Fiber Optic Link provides a high-quality system
for transferring baseband video signals with complete EMI immunity
via fiber optics. The FM technique employed results in a plug-and-play
system that requires no user adjustments. While optimum performance
is achieved with an RS-250C video input, the output level tracks the
input level over the entire optical loss range. Available for use
with either single-mode or multimode fiber, the link uses 850 nm,
1310 nm, or 1550 nm optics for high reliability. Each unit is built
in a rugged enclosure that offers excellent EMI and RFI shielding.
The adaptability of the Model 2768 makes it an excellent choice for
a contribution video link or for tunnel monitoring, radar remoting,
and shipboard applications.
RS-232 or RS-422 Fiber Optic Daisy-Chain Transceiver
- Model 2769
The
Model 2769 RS-232 or RS-422 Fiber Optic Daisy-chain Transceiver increases
the transmission range (compared to copper) of RS-232 or RS-422 data
signals in a linear bus topology. Each unit is a complete daisy-chain
transceiver capable of full-duplex data transmission. Operating over
an optical loss range of 21 dB, the link is DC coupled and will handle
bursty data or long periods of time between data bits. A backup power
source, NiCd batteries, allow continuous operation for up to 24 hours
after a loss of primary, +12 Volt DC power to the unit. Single-mode
1310 nm optics and STTM optical connectors ensure reliable
performance. The unit is available in a 4RU rack-mount configuration
in addition to the rugged stand-alone module. These units are ideal
for polled security systems, computer LAN, process control, and I.T.S.
applications.
RS-232/RS422 Fiber Optic Self-Healing Ring
Transceiver - Model 2869
The
Model 2869 RS-232/RS422 Fiber Optic Self-healing Ring Transceiver
is designed to support full-duplex, asynchronous RS-232 or RS-422
type data communications in a multidrop, counter-rotating ring topology
over multimode or single-mode optical fiber. Proper implementation
of the Model 2869 allows for totally redundant, fault-tolerant, self-healing
operations, providing uninterrupted communications between network
nodes, even if a fiber break occurs or one or more transceivers in
the ring fails. Each transceiver can be configured as a master, a
local, or a submaster unit. State-of-the-art electro-optics are deployed
for maximum unit reliability. All optical signals are fully regenerated
at each transceiver, ensuring transparent, error-free data transmission
throughout the network. The unit is available in a 4RU rack-mount
configuration in addition to the rugged stand-alone module. These
units are ideal for polled security systems, computer LAN, process
control, and I.T.S. applications.
