Noise Bandwidth 4.2 MHz

(1). Broadband Forward Path

(2). Return Path. Guaranteed by design, not to test in production.

In order to prevent reflection-induced distortion, the laser must be connected to an optical cable having a return loss of at

least 55 dB for discrete reflections and 30 dB for distributed reflections.
