2.2	Product Description
A. 	The 9421D series of transmitters/receivers shall digitize and transport two video channels, one duplex High-Speed port data channel, and two Option Module channels over one optical fiber, with the Option Module channels operating in both directions.
B.	These transmitters/receivers shall also provide:
1.	High quality video ≥63 dBw SNR.
2.	Uncompressed 9-bit digitizing, oversampling, and digital filtering for a very high transmission performance, exceeding the requirements of the EIA RS-250C medium haul specification.
3.	A high-speed port that shall support 1.5 Mbps RS-422 or connection to optional Option Module host cards, for transport of four or eight duplex audio, data, contact closure, or 10 Mb/s Ethernet signals. 
4.	Two Option Module channels, which shall provide additional transport for any combination of two data, audio, contact closure, or intercom channels on the same fiber as the video and High-Speed port channels. 
5.	LED indicators to provide an instant overview of the system status.
6.	Compatibility with Network Management System (NMS).
C.	The system shall operate 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.
D.	These units shall be built for rack-mounting. 
1.	They shall be compatible with a 9002, 9008, or equivalent, power supply cabinet.
2.	They shall be configurable to stand-alone by using a model 9003-2 min-chassis or equivalent.
2.3	DESign and Performance Criteria
A.	The 9421D transmitter/receiver modules shall transporting two NTSC, PAL, or SECAM video signals, two duplex user-selectable Option Module Port signals, and a high-speed duplex RS-422 data port signal over one optical fiber. 
B.	The video shall be encoded using a 9-bit uncompressed digital technology combined with the data and transmitted on the fiber digitally.
C.	The 9421DT transmitter shall accept two composite video signals in NTSC, PAL, or SECAM format via two BNC video input ports. 
1.	The baseband video signals shall each be sampled at a 16 MHz rate by an analog-to-digital converter operating with 9 bits of precision. 
2.	The signals shall be multiplexed, serialized along with the serial data from the option modules and the high-speed port, and converted to an optical signal for transmission over the fiber. 
3.	For the reverse direction, data shall come into the transmitter via an optical receiver operating at a different wavelength than the transmitter. The received data stream shall be demultiplexed into data for output via the Option Modules and high-speed port.
D.	The 9421DR receiver shall accept the optical signal and demultiplex it into bit streams for the video and the data. 
1.	The video stream signal shall be deserialized and converted back into the video signals, which are output at the BNC connectors. 
2.	The data stream shall be demultiplexed and sent to the Option Modules and high-speed port. 
3.	For the reverse direction, outputs from the Option Modules and high-speed port shall be multiplexed together and converted to an optical signal for transmission to the transmitter on the second wavelength.
E.	The system shall support two Data/Audio Option Modules, each of which shall operate bi-directionally. 
F.	The high-speed port shall operate in both directions and provide a simplex 16 MB synchronous RS-422 port, for the primary purpose of supporting these optional accessory cards: 
1.	9961-C or 9962-C Option Module Host cards, which shall add data, audio, and contact closure channels
2.	9971-C high-speed port to 10 Base T Ethernet card, which shall have two user-programmable serial data ports and one full or half duplex 10 Base T Ethernet link.
G.	 The high-speed port shall be able to serve as a 1.5 Mbps asynchronous RS-422 port.
H.	These transmitter/receiver units shall come as rack-mount, plug-in cards that occupy one card slot in any compatible card chassis (such as a Series 9000). 
1. 	The rack-mount units shall be optically compatible with the standalone models.
2.	The units shall operate on 6VDC from the chassis power supply.
I.	The units shall operate through a wide temperate range (-40° to +74° C / -40° to +165° F).
J.	The units shall meet UL/cUL, CE, and FCC part 15 regulatory requirements and be RoHS compliant.
