Kaiam Releases QSFP Modules for Telecom and Datacom Applications

Kaiam, optical component developer and manufacturer, will demonstrate its 40 Gb/s Transmitter and Receiver Optical Subassemblies designed for LR4 Applications at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) 2011 in Los Angeles.

Kaiam’s 4 x 10 Gb/s TOSA and ROSA are capable of receiving and delivering a cumulative 40 Gb/s with a 10 km reach in a single mode fiber. The company’s hybrid integration technology is capable of achieving high densities required for small form transceivers. The subassemblies are designed for use in QSFP modules for high bandwidth routers and switches in enterprise datacenters and networks. The subassemblies can also be used for telecommunications equipment. Opnext’s uncooled 1310 nm lasers helped develop the QSFP package with open RF characteristics.

Alignment issues are usually encountered in hybrid packages. Kaiam utilizes silicon micromechanics to address such issues and develops photonic integrated circuits (PICs) for various applications. The low-cost PICs can be tested before assembly and therefore deliver high yield in manufacturing.
