The output spectrum of the green LED is produced by a Gallium Nitride die which peaks at a wavelength of 530 nm, ideally mapping to the lowest attenuation window of PMMA plastic core optical fiber. The device package features an internal LED micro-lens, and the PBT plastic housing ensures efficient optical coupling into standard 1000 µm core plastic fiber cable.

When coupled to PMMA plastic optical fiber, attenuation is less than .1 dB/m, as compared to .16 dB/m with commonly used 650 nm LEDs. Using standard 1 mm core plastic fiber, the IF-E93 LED is capable of distances in excess of 150 meters at data rates of 5 Mbps. The fast rise and fall times of the IF-E93 permit data rates up to 30 Mbps. The drive circuit design is simpler than required for laser diodes, making the IF-E93 a good, low-cost alternative in a variety of analog and digital applications.
