Manufactured using the same technique as the Model 954P fixed ratio coupler, but with SM non-PM fiber.

These very low loss couplers allow CW power approaching that of the fiber itself.
The only restrictions we have noted is very high peak power, picosecond and femtosecond pulses that cause non-linear changes in the fiber that increases loss due to reduced guidance.
