LYNX Technik has expanded its yellobriks product line with two new fiber-optic CWDM (Coarse Wavelength Division Multiplexing) multiplexers/demultiplexers, the OCM 1892 and the OCM 1891. The company will launch the new CWDM multiplexers/demultiplexers at IBC 2010.
The yellobrik Fiber Optic Transmitter now features the CWDM capabilities. These fiber interfaces are suitable for studio broadcast, and fixed and mobile production applications. The OCM 1891 and the OCM 1891 are also used in professional AV installations such as medical imaging, distance learning, digital signage, and the applications that need transmission of broadcast quality video over long distances.
The bi-directional fiber-optic CWDM demultiplexers/multiplexers can transport multiple SD SDI/HD/3G video signals through a single optical cable. These multiplexers combine a maximum of nine CWDM channels into one fiber link, to multiply the existing single mode fiber’s capacity. The OCM 1891 multiplexer can be utilized along with the OCM 1892 for increasing the optical channels number from 9 to 18, which can be transported through a single fiber cable.
Both the fiber-optic modules can be fitted in a yellobrik half RU rack mount, offering maximum of 18 optical demultiplexing/multiplexing channels. The OCM 1892 multiplexer supports transmitter frequencies of 1450 – 1610 nm, while the OCM 1891 supports 1270 - 1430 nm. These multiplexers are passive devices, hence, do not need power.
