Hewlett-Packard can offer a ruggedized fiber pigtail for this product range if extreme mechanical strength is required. The pigtail length can be

customized to your specific length, with a connector, to a tolerance of

±25 mm.

Note:

1. Fiber output power change for constant monitor output current.
