Optical Multiplexing

Wavelength Division Multiplexing (WDM) allows two or more signals to be combined (multiplexed) on a single fiber by using different wavelengths for each signal. It can be uni or bi-directional and is particularly useful when minimizing the fiber count is advantageous e.g. when the fiber is being leased. It utilizes 1310 and 1550 nm lasers and high isolation is achieved between channels (90 dB RF) to maintain excellent signal integrity. Read more »

Performing software updates on all ViaLite M&C Products

ViaLite continually works to improve its products and software. Several ViaLite products can be updated upon the release of new Monitoring and Control (M&C) software. As part of this, software updates are regularly issued for the Horizons HRC and site controller products, which are used to fully monitor and control ViaLiteHD RF over fiber systems. This guide details how to perform these updates. Read more »

How to Extend an Antenna Cable with GPS over Fiber Technology

In the context of providing indoor GPS, the length of a coaxial cable generally is limited to around 100 meters, due to the effects of attenuation and increased noise. Even a well-screened, low loss coaxial cable can be affected by EMI, causing delays and data packet corruption. By comparison, the distance from antenna to receiver can be up to 10 km over single mode fiber. Read more »

GPS / GNSS Antenna Loading – Alarm States

All ViaLiteHD GPS RF over Fiber products come with a GPS mode that senses and mimics the operation of an active GPS antenna as standard. This allows the GPS antenna to be current sensed by the RF over fiber transmitter. If there is no current loading on the RF connector port, either due to no connection or a fault with the amplifier in the antenna, the transmitter switches off its laser, forcing an alarm condition at the receiver end. This allows the user to know there is a fault in the system. Read more »

ViaLite Monitoring & Control Module Features

The ViaLite Monitoring and Control (M&C) modules can be used to fully manage ViaLiteHD RF over fiber systems. The HRC-1 was our first generation product for local and remote monitoring of RF over fiber systems. The HRC-3 was designed as an upgrade to provide additional features. The Site Controller offers an embedded option for several of ViaLite’s outdoor enclosures. Read more »

Automatic Gain Control

Automatic Gain Control (AGC) mode is a feature available in both ViaLite Transmitter and Receiver modules (including Dual Transmitter modules, Transceiver modules, etc.). In order to set the AGC control on the module, and specifically for the transmitter module, it’s important to understand how RF signal power is measured and reported. Read more »
