This Lightwave Transmitter is a high performance digital lightwave transmitter designed for optical communications up to 12.5 Gb/s bandwdiths. It has an internal L-band 10mW DFB laser, a 13.5GHz Lithium Niobate (LN) Mach-Zhender Modulator, and an ultra-broadband RF driver. Instead of the built-in DFB, users can also use an external tunable laser with the transmitter. It is compliant with standards such as OC-192, STM-64, and 10G Enet. Optical links can be established quickly with this product.
