# SAM #80NSSC27948034Q NASA sole-source procurement of 60 custom Thorlabs hermetically sealed fiber-optic assemblies **Buyer:** NASA Shared Services Center **Posted:** October 28, 2026 **Respond By:** November 02, 2026 **Identifier:** 80NSSC27948034Q **NAICS:** 334516, 335921 NASA is pursuing a proposed sole-source purchase from Thorlabs for custom hermetically sealed fiber-optic assemblies supporting the SCALPSS 2.0 project. - **Agency and approach:** NASA Shared Services Center (NASA/NSSC) is the procuring center; delivery/performance is associated with NASA Langley Research Center. The notice seeks capability statements only, and quotes will not be considered. - **OEM:** THORLABS, INC. is the named source. The justification cites specialized manufacturing and performance requirements, and schedule risk from other vendors’ lead times. - **Specified order:** 60 custom assemblies, part number FFH05026-CUSTOM: 20 assemblies at 5 m and 40 at 1 m. Each uses FFH05026 fiber, a hermetically sealed stainless-steel microtube with internal structure FT052SSB-SABR, vacuum-compatible epoxy equivalent to MFV1L1, and special-order hermetic SMA connectors at both ends. Length tolerance is ±20 cm, and a generic certificate of conformance is required. - **Additional attachment detail:** A separate justification description identifies a 20 cm configuration but does not give a quantity; the order specification separately lists the 1 m and 5 m configurations. - **Delivery and schedule:** Delivery is to NASA Langley Research Center. The stated lead-time plan is 10 weeks after receipt of order (ARO) for the first five units of either configuration, followed by five units per week, with all 60 units completed within 22 weeks ARO. An attachment estimates performance from October 30, 2026, through March 30, 2027. - **Mission context:** The justification warns that schedule delays could jeopardize SCALPSS pre-flight integration and its planned lunar mission. ### Description
