ASFOM Point-to-Point Transmission
The KBC ASFOM range allows you to effectively design your own product to meet your own specification. ASFOM products support: analog video, data, analog audio, contact closure, telephone and Ethernet in various permutations to meet your exact requirements. All signals are digitized 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 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. Depending on system requirements, units are available in wall-mount, 1U or 2U 19” rack or 4U chassis card for integration within the FR4 chassis.
