2.2	PRoduct DESCRIPTION
A.	The Tetra 4300 series of multiplexers shall simultaneously transmit four camera signals with two audio, four data, and two contact closure signals, and one 10/100Base-TX Fast Ethernet interface over one single-mode or multimode optical fiber. An extended distance (ED) unit shall be available for long distance applications.
B.	The multiplexer shall provide:
1.	Uncompressed 10-bit digitizing, oversampling, and digital filtering, which shall exceed requirements of EIA RS-250C medium-haul specifications. 
2.	A 10/100 Mb/s Fast Ethernet (IEEE 802.3) interface with autonegotiation, autosensing, and auto-MDI/MDI-X for a fast, reliable connection.
3.	Four full-duplex data channels
4.	Two CD-quality, full-duplex audio channels
5.	Two full-duplex contact closures for isolated alarm input and output contacts.
6.	Compatibility with Smart Network Management (SNM™), to provide information on all transmission parameters.
7.	Bidirectional RS-232, RS-485/422 data interface which shall support serial data such as PTZ data from all types of cameras. Supported interfaces shall include RS-485, TTY, Manchester, Bi-phase, and SensorNet. 
8.	LED indicators to provide an instant overview of the system status, including power and system faults.
C.	The system shall be highly suited for use in situations such as:
1.	In a wide range of operating temperature and in harsh weather conditions, such as in traffic monitoring, incident management, video surveillance in city centers, and airport security.
2.	The need for a compact and versatile combination of video, audio, data, contact closures, and Ethernet, can be deployed effectively in almost any CCTV application.

D.	These units shall be available for rack-mounting or as stand-alone units.
1.	Rack-mount units shall occupy one card slot each in a MC-10 or MC-11 power supply cabinet.
2.	Stand-alone units shall be compatible with a PSA-12 DC/25 or PSR-12 DC power supply unit.
2.3	DESIgn and Performance Criteria
A.	This series of digital-optical multiplexer/demultiplexer systems shall transmit signals through four unidirectional, independent composite video channels and two audio, two contact closure, four data channels, and Fast Ethernet.
1. 	All transmissions shall be bidirectional, independent and transparent, using one single-mode optical fiber per system.
2.	The 4310 versions of this multiplexer shall use multimode fiber. The 4350 versions shall use single-mode fiber.
3.	The video and data/audio input signals shall be sampled at a rate of 15 MHz and digitized with 10-bit accuracy. 
B.	The -TX model transceivers shall:
1.	Convert and combine composite video, audio, data, contact closure, and Ethernet signals into one digital stream, which shall then be converted into an optical wavelength of 1310 nm. 
2.	Convert and decode an incoming 1550 nm optical signal carrying a digital stream of data, audio and contact closure signals. 
C.	The -RX model transceivers shall:
1.	Receive, convert and decode video and other signals arriving through the optical fiber.
2.	Convert and combine audio/data/contact closure, and Ethernet inputs, then transmit this information optically towards the complementary TX, using an optical wavelength of 1550 nm. 
E.	The composite video channels shall be capable of being all individually set to transparent mode (by setting video clamping to off).
F.	The video channel operation mode and several switching functions shall be accessible through software, using the SmartNet management system (SNM). 
G.	Several aspects of data and audio interfacing shall be controllable by means of circuit board dip switches and jumpers. 
H.	The data port D1 and D3 interfaces shall be set up for compatibility with RS-422, RS-485 2W, RS-485 4W, and Manchester PTZ (bi-phase) data.
1.	With modified cabling, the RS-422 interface shall be configurable for digital current loop/TTY applications. 
I.	Data ports D2 and D4 shall be set up for adjustment free RS-232 operation. 
1.	The inputs of the 4-wire audio interfaces can be set to high or low impedance, balanced or unbalanced. 
J.	The data channel I/O compatibility (RS-232, RS-422, RS-485-4W and RS-485-2W) and termination configuration shall be selectable via an on board 10 position dip-switch. 
K.	These units shall come as double-width (14TE), Eurocard-sized modules.
1.	They shall be compatible with MC 11 or similar power supply cabinets. 
2.	To use SNM management, the EB-2 versions of the MC 11 cabinets are recommended.
3.	Stand-alone models shall require separate 12VDC power supply (such as a PSA 12 DC-25). 
L.	These units shall consume <12W (2A inrush) power.
M.	These units shall operate through a wide temperate range (-40° to +74° C / -40° to +165° F).
N.	The system shall hold safety certifications including UL/IEC/EN 60950 and IEC/EN 60825. They shall meet CE immunity and emissions requirements to include IEC/EN 61000, EN 50130-4, EN 50081-1, EN 55022, FCC Part 15 and RoHS compliance.
