Fiber Optic Modular Switch

PROJECT TITLE: Fiber Optic Switch LOCATION OF WORK: Supplies to be delivered to: Radar Operations Center 1313 Halley Circle Norman, OK 73069 THIS IS A REQUEST FOR INFORMATION. The Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA) is seeking sources capable of providing ABB Switzerland Pulse Power Switch Assemblies and associated Light Distribution Boxes or equal. NOAA is not seeking vendors to design, develop, and ten produce this requirement; we are seeking vendors already capable of providing a working solution. DESCRIPTION: The purpose of this requirement is to replace the High Energy semiconductor switches used in the Line Modulator circuitry of the transmitter within the NEXRAD Weather Surveillance Radar WSR-88D. The switch, when triggered to the "On" state, discharges the Pulse Forming Network within the modulator which has previously been charged to 5200 Volts maximum. The large current which results brings a Klystron into conduction. The existing switch is made with Reverse Biased Diode Thyristors (RBDT's) which are becoming obsolete. NOAA's Acquisition & Grants Office, Western Acquisition Division-Boulder, in support of the NWS Radar Operations Center (ROC), seeks potential vendors to provide 245 High Speed Fiber Optic Switches with an accompanying Light Box. This "Brand Name or Equal" procurement (FAR 6.302-1(c)) is of sufficient quantities of ABB Switzerland Pulse Power Switch Assemblies and associated Light Distribution Boxes to support the WSR-88D radar fleet. Specific part numbers include: ABB Switzerland LTD Part Number 5SVC 032708E130 Pulse Power Switch Assembly OR EQUAL ABB Switzerland LTD Part Number 5SVB 020408T130 Light Distribution Box OR EQUAL The salient characteristics of the existing RBDT switches are ten RBDT's stacked in series with suitable compression clamp hardware. Each switch has a minimum forward biased hold off voltage of 1100 volts giving the entire stack a hold off voltage of 11000 volts minimum. The normal forward biased stack voltage is 5200 volts maximum with an over voltage protection threshold of 5600 volts nominal. Provisions are made for proper operation with one RBDT shorted accompanied by the setting of a "Maintenance Required" alarm which alerts the operator of the problem. Due to the stringent availability requirements (96%) and unmanned nature of the NEXRAD transmitter, this feature is essential, especially in storm season. The Modulator is designed to operate with a maximum duty cycle of 0.004. The Modulator is capable of operation in two modes: Short pulse (1304 pulses per second maximum with a Pulse Width of 3 usec) and Long pulse (452 pulses per sec maximum with a pulse width of 6 usec). The switch must support this operation. The peak current per pulse is 896 amps maximum during the entire pulse width. Cooling air is supplied to the Modulator. Cooling requirements of the switch shall be stated in any responses to this request. The space available for the switch assembly is approximately 8 inches X 8 inches X 8 inches. Specifically, NOAA requires the following units; CLIN 0001 1EA High Speed Fiber Optic Switch with accompanying Light Distribution Box - First Article CLIN 1001 4EA High Speed Fiber Optic Switch with accompanying Light Distribution Box - Limited Rate Initial Production CLIN 1002 240EA High Speed Fiber Optic Switch with accompanying Light Optional Item - Full Production DELIVERY SCHEDULE: First article units will be delivered to the ROC in Norman, OK 60 days after receipt of order. Developmental support units are due in 60 days of an approved First Article and full production is due within 6 months of LRIP. The Government anticipates awarding a fixed-price supply contract for the cables. This request for information does not constitute a commitment, implied or otherwise, that a procurement action will be issued. No entitlement to payment of direct or indirect costs or charges by the Government will arise as a result of the submission of contractor's information. The Government shall not be liable for or suffer any consequential damages for proprietary information not properly identified. Proprietary information will be safeguarded in accordance with the applicable Government regulations. Please submit information to include: 1) Your firm's DUNS number & CAGE code; 2) Your firm's SBA certified small business concern status. Specifically identify if your firm is HUBZone-certified, Service Disabled Veteran Owned, or SBA 8(a) program certified; 3) A brief description of your firm's ability to provide a fiber optic switch ABB Switzerland LTD Part Number 5SVC 032708E130 and 5SVB 020408T130 or equal. 4) Identify any major work components that your firm would likely subcontract out. Information must be received by the Contract Specialist, Ms. Sue Bratton (Affiliate), at contact@example.gov by close-of-business on Friday, March 6, 2015. Do not call regarding this sources sought notice. Any questions or responses regarding this notice must be submitted in writing via e-mail to the above e-mail address.
