Multi-Mode CCTV Transceivers

The Courier Systems™ is a fiber optic transmission systems designed for unique applications requiring pick up and delivery of video transmission along with associated Ethernet, P/T/Z data and audio or auxiliary communication signals such as contact closures or alarm signals. The Courier System™ uses Nitek's unique Universal-Mode™ optics allowing the same unit to be used with either single-mode or multi-mode fiber optic cabling types. The systems are designed to offer broadcast quality video transmission without compromise. The video is transmitted in a real time full bandwidth digital format. This ensures the highest quality regardless of distance, and by transmitting the video in an uncompressed format, there is no latency or loss of video quality. The Courier System™ can be configured to collect individual or multiple video signals along a given route or perimeter in a daisy chain and transmit them all back to one or more control rooms. This allows for significant savings on fiber optic infrastructure when compared to traditional methods of video collection. The architecture allows for configuration in either a "spur" or a "ring". The Courier System™ has an option to be set up in a dual redundant configuration which helps to ensure against loss in a catastrophic fiber failure. Using Coarse Wavelength Division Multiplexing (CWDM) up to 16 wavelength channels can be used providing a transmission capability of up to 128 video channels on a single optical fiber together with the associated data/audio and Ethernet. When configured as a fiber ring using eight strands of fiber the system has a capacity of up to 512 video channels, 1,024 data/audio channels and 6.4Gb of Ethernet. The Courier System™ can be delivered with a dedicated Network Management System (NMS), providing alarms associated with breaks in optical fiber and video loss notification.

→ Real time digital transmission eliminates signal degradation associated with distance.
→ Universal-Mode allows the same unit to be used with multi-mode or single-mode fiber without any set up or field configuration.
→ Simultaneously transmits multiple video, Ethernet, control, audio and auxiliary communications all in one set of equipment.
→ Directly supports all NTSC, PAL or SECAM video formats.
→ Dual redundant option eliminates system downtime due to fiber failure.
→ SNMP compliant network management option for remote fault monitoring and reporting.
