The compact transceiver is designed using advanced ASIC and high-speed DSP
technologies. This series employs multiplexing and de-multiplexing techniques to transmit
and receive video, data, and contact closure over a single-mode or multi-mode optical fiber
in all digital signaling with no compression; making it ideal for applications where input
signal integrity and quality must be maintained and no loss should be induced. Because the
series utilizes all-digital, non-compression technology, it is able to transmit signals without
distortion; whereas the analog technology inherently noisy, low quality, long term instability
and susceptible to electromagnetically and environmental interference. This series accepts
a variety of video inputs, such as analog or digital video recorder, DVD/VCD, digital camera,
and CCTV. PAL, NTSC and SECAM standards are supported. It supports standard
RS232/RS422/2 wires RS485/4 wires RS485 pan-tilt-zoom control signaling. Contact
closure can be used to control remote I/O switch such as power supply switch or alarm/alert
indicators. Plug-and-Play design ensures ease of installation and no electrical or optical
adjustment is required. LED indicators are provided for showing operating status.
The compact transceiver is fully assembled using SMT components for stability and
reliability.

The Contact Closure state, Open or Close, of the contact closure on the
receiver end follows the state of the contact closure on the transmitter end. I.e.
if the contact on the transmitter end is Close, the contact on the receiver end
is made to be Close. If the contact on the transmitter end is Open, the contact
on the receiver end is made to be Open.

① The 2 wires RS485/4 wires RS485 output bus pull-up and pull-down resistance usually should be
switched on. But if there are several fiber transmitters or receivers, 2 wires RS485/4 wires RS485
output interfaces are connected together, only one of the 2 wires RS485/4 wires RS485 output Pull-up
and Pull-down resistance should be switched on, the others should be switched off.
