CWDM Single-Fiber Connectivity for Satellite Uplinks

This military fiber network application diagram shows how to add new data channels to an existing single-fiber link that connects a communications room and a satellite uplink antenna without installing new fiber.  At the communications room at the left of the diagram, four Gigabit fiber links from Ethernet switches are connected to an iConverter 4-Channel Single-Fiber CWDM Multiplexer installed in an iConverter 1-Module Passive Chassis.  CWDM Small Form Pluggable (SFP) transceivers are installed in the switches, and each of the four CWDM SFPs are connected to the corresponding wavelength Channel Ports on the CWDM Mux using fiber patch cables (as shown in different colors to represent the different wavelengths).  All four wavelengths are transported over the CWDM Common Line, or the single-fiber link, and each wavelength is an independent data channel.  With single-fiber, each two-way data channel is two wavelengths, so with CWDM over single-fiber, each CWDM Channel is also two wavelengths; one transmit and one receive.

At the other end of the CWDM Common Line, another iConverter Single-Fiber CWDM Mux is installed in an iConverter 5-Module Chassis with four iConverter GX/T2 Gigabit copper to fiber media converters. This configuration enables connectivity between the fiber channel ports on the CWDM Mux, and the copper RJ-45 ports on the satellite uplink.  CWDM Small Form Pluggable (SFP) transceivers are installed in the fiber ports of the GX/T2 media converters and are connected with fiber patch cables to the Channel Ports on the Single-Fiber CWDM Mux. Each GX/T2 media converts the CWDM wavelength fiber to Gigabit copper, and UTP cables connect to the satellite uplink. 

iConverter CWDM Multiplexers support up to 16 channels, and each channel can transport up to 10G per channel.

Fiber Connectivity for Missile Systems

This application example shows how to connect a single fiber link to a copper RJ-45 port on a missile system.  Fiber is run from a fiber switch in a control room to missile system, where a miConverter Miniature Media Converter provides copper to fiber conversion.  The miConverter has a compact form factor that can easily be integrated into other systems, and is temperature hardened for outdoor deployments.

Extend Serial Communications Distances to Radar Installations

The iConverter X21 serial to fiber converter enables controlling radar installations from remote distances by extending X21 and serial 530 Crypto Circuits over Fiber to SATCOM Antennas and Radar Installations. The iConverter X21 supports fiber links of up to 120km over single-mode fiber, and is wide temperature hardened for extreme environments.

Extend Distances to Targets in Digital Training Ranges

This application example illustrates how Omnitron Copper-to-Fiber Media Converters enable fiber connectivity to targets in a digital training range. The network can be Fast or Gigabit Ethernet, the fiber can be dual or single-fiber.

A high-density chassis of media converters enables up to 18 fiber runs from an Ethernet switch with RJ-45 ports in the control tower to digital target sensors on a training range.

At the end of each fiber run a standalone media converter converts the fiber to copper for connectivity to the digital target. The NEMA enclosure provides weather-proof durability, and Omnitron media converters are hardened with an operating temperature range of -40 to +85^oC for deployments in severe environments.

Omnitron’s iConverter Managed Media Converters, FlexPoint Unmanaged Media Converters, or miConverter Miniature Media Converters can be deployed in this application.
