In Detail

The ASFOM enables application specific product configuration and build. Using ‘configurator’ software, you choose the mix of signal types as well as the exact number of channels per signal type. ASFOM products support: analogue video, data, analogue audio, contact closure, telephone and Ethernet in various permutations to meet your exact requirements. All signals are digitised providing excellent quality and guaranteed performance throughout the system. Video is offered with either 8 or 10 bit digital resolution without compression, providing real-time video images across the link.

ASFOM products can be configured for multimode or singlemode operation and are available in either two or single fibre formats. Based on the channel requirements and signal mix, the ASFOM will utilise single wavelength, WDM or CWDM (Course Wave Division Multiplexing) technology. The CWDM optics enable up to 128 real-time video signals in a single fibre or various mixtures of signal type in large quantities.

The ASFOM range encompasses both point-to-point and Bus transmission system options. The Bus Transmission System allows optical bus systems to be configured simply and easily. Using CWM technology up to 16 optical wavelengths can be combined in a single fibre to create an additional add/drop bus arrangement. In effect the system is 16 individual point-to-point links integrated via the CWDM.

Depending on system requirements, units are available in wall mount, 1U or 2U 19” rack or 4U chassis cards.
