UTEL 903 OTDR
The UTEL 903 OTDR (Optical Time Domain Reflectometer) is at the heart of our centralised testing system. It can be used to test Passive Optical Networks (PONs), point-to-point and dark and lit fibre, using a single test head.
The UTEL 903 OTDR works with our cloud-based monitoring and analysis software. The OTDR’s sophisticated event analysis capabilities are combined with the comprehensive management and reporting functions available in in our planning software, for a complete solution.

Remote Optical Switch Controller (ROSC)
Our remote optical switch controller (ROSC) is part of the UTEL testing system designed to facilitate economic monitoring and validation of rural PONs. The ROSC extends the range of our centralised testing system by enabling the optical switches to be located up to 20km from the UTEL 903 OTDR test head.

Optical Switch with Wavelength Division Multiplexing (WDM)
UTEL’s range of optical switches, with integrated WDMs, are optimised for limited space installations, such as fibre street cabinets. They are also suitable for central office applications and remote exchanges. The switches are used in conjunction with the UTEL 903 OTDR and ROSC as part of UTEL’s centralised planning and testing system.
Wavelength Division Multiplexing (WDM) Tray
UTEL’s WDM trays allow the UTEL 903 OTDR 1650nm test signal to be effectively injected into the network. The ITU-standard 1650nm signal is outside the transmission wavelengths of 1310nm and 1550nm. Thus, the WDM tray allows the test system to be used from the early build stages to in-service, without any change of equipment or interruption to service traffic.

Power Monitoring Optical Bypass Switch
The Optical ByPass Switch monitors the state of the fibre and takes one optical path when it is powered and a secondary path when the power is removed. Each unit manages two fibres and can bypass equipment using transmit and receive channels.

Remote Battery Power Switch
The UTEL Remote Battery Power Switch enables operators to prioritise backup power to different services when the mains power supply is cut. In areas with frequent power outages, this switch provides control over how battery backup power is deployed. A typical application is to disconnect high power consuming services as battery power diminishes, so as to maintain essential services for as long as possible.
