See datasheet at 1st pdf link below. 250um-coating bare fiber pigtail without connector. Fiber looks very long. For this Oclaro model: LC95ZKH74P-20R, kink-free output power would be much larger than 270mW in most cases. The 2nd page of 1st attached pdf specification shows: "Operating power assumes a 10% ageing margin", so you can use at operating power = kink free power / 1.1 For this Oclaro model: LC95ZKH74P-20R, kink-free output power of actual test data would be much larger than 270mW mostly, so customers can use them at much higher than 245mW in their actual system products. This thumb of rule is quite accepted by EDFA makers, especially for Oclaro pump lasers. Kink-free power test data are at 746mA, so max operating power could be chosen around 700mA(also about 10% margin for current). These lasers are designed as pump sources for erbium doped fiber amplifier (EDFA) applications. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilize the wavelength. The LC95 series pump module utilizes a fiber Bragg grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes.
