Signal light sources
We have a lineup of InP-based semiconductor lasers that we have developed over many years, mainly for use in intensity modulation/direct detection (IMDD) communications, where the transmission distance is short.
Intensity-Modulation and Direct-Detection (IMDD)
Chip-type LD products that can be integrated into silicon photonics devices.
Pump light sources
FITEL brand has been top class supplier of 1480nm band pump light sources since 1999, and has a high level of reliability.
Raman amplifier applications
Lower power consumption lasers with FBGs of 400 mW or more.
Higher output power lasers with FBGs of 600 mW or more.
EDFA applications
Fabry-Perot (FP) lasers with built-in isolators of 400 mW or higher.
