The Optical Internetworking Forum (OIF) is developing a specification for a micro-integrable tunable laser assembly (uITLA). This new form factor for tunable lasers is needed as the industry moves to an XFP form factor with reduced power dissipation.
The new uITLA project will propose changes to the assembly electrical interfaces, optical specifications, and mechanical specifications and provide an alternative laser solution for ITLA customers contemplating the integration of a specific vendor “gold box” laser on the host PCB due to space constraints. The aim is to cut the real eastate used on the base plate area by half compared to today's ITLA-MSA-1.2 modules.
