The transmitter module features a V-connector for the electrical input signal. A 50/125-micron multimode fiber handles the optical output; a standard FC/PC connector terminates the fiber.
The VM64-850M transmitter module has a footprint of 62.5×16.7 mm. The height of the module is specified as 8 mm. The fiber cable length is typically 1 m.
The maximum optical output power is specified at 4 mW. The typical operating voltage is 2.4 V.
VI Systems will present the module at OFC 2016 this month in Anaheim, CA.
