- Description
- Responses to three questions from potential Bidder: 1.The specification does not explicitly state if the RF input power of 10 mWatts is max non-damage, or as I assume, a input P1dB minimum value. Correct, the input power is the P1dB minimum value. There is not a max non-damage specification for this solicitation. 2.In our experience of delivering high performance C-Band systems, there should be a corresponding phase noise specification. Does the end user have a specification, or is industry standard acceptable. The noise figure specification is less than < 20 dB corresponding phase noise was not originally specified but typical -40 dBc/Hz minimum -100 dBc at 100 Hz offset. Which is pretty much industry standard for such systems up to 6 GHz. 3.The specification for 1310 UL / 1550 nm DL implies that there is a downlink channel. Or, is this reference the desire is to have the remote monitor capability to utilize 1550nm? Please provide any clarifications For this procurement, the vendor only need be concerned with the uplink channel (UL). But for information and clarification; There are two down link channels one in the S band and another in a lower C band that we are handling independent of the uplink system (DL system already supplied with the existing antenna). The questioned specification reference is for fiber and connector compatibility with other parts of our system in the event that vendor provides fiber in pairs. If so, then we have option to use the vendor supplied fibers as spares for our other channels and vice versa our other channel paired spares would be compatible with vendor UL system.
