ST UPC Duplex OS2 Fiber Adapter with Flange, 10pcs/Pack

For procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. ST UPC Duplex OS2 Fiber Adapter with Flange couples two fiber connectors into one continuous optical route. Inside the housing, a zirconia ceramic sleeve holds the two ferrules on a common axis, keeping insertion loss low and stable across hundreds of mating cycles. The flanged housing screws directly to this adapter panel cutout for a permanent, vibration-proof mounting.

Product Highlights

• ≤0.2dB (Typical) Low Insertion Loss
• ST Guarantees for Long-term Stable Mechanical Properties and Repeated Matching
• Zirconia Ceramic Sleeve with High Precision Alignment
• Protective Dust Cover Keeps the Inside of The Adapter Clean From Dust
• Threaded Adapter for Easy Installation and Removal

Each optical adapter is, at heart, a sleeve alignment problem: two connector ferrules must meet on one axis with their end faces touching, and any eccentricity shows up directly as insertion loss. Zirconia ceramic is the standard sleeve material since it machines to sub-micron tolerance, resists wear across repeated matings and holds its dimensions through temperature swings. The adapters in this range use zirconia sleeves rated for insertion loss of 0.2 dB or better, which keeps an adapter pair well inside any optical loss calculation.

Panel work consumes adapters in dozens, not singles: a frame reload takes a full pack, and the spares kit must hold more against breakage, contamination and the adapter housing that vanishes during a hurried re-entry. The ten-piece pack format matches that reality - one pack per panel location covers the load-out with spares, and the unit cost drops well below single-piece pricing. Bulk packs further guarantee that each adapter on this adapter panel is the identical revision, the identical color and the identical sleeve quality.

A disciplined panel installation kit counts everything before the van leaves: adapters at one pack per panel plus a spare, caps for each unused port, the screws or clips this adapter panel needs, and the cleaning supplies that keep end faces serviceable. Adapters are the cheapest line on that list and the one whose absence stops the job outright. The bulk pack format makes the counting simple - two packs per location and the location is covered, current and spared.

A flanged adapter fastens to this adapter panel with two screws through the mounting ears: the joint is rigid, resists vibration and stays put for years, which suits frames and enclosures that move or ship. A flangeless adapter snaps into the cutout on spring latches: unit is faster, density is higher, and a failed adapter swaps out in seconds without tools. Most panel families accept one style or the other, and therefore the option follows this adapter panel hardware already in the plant.

An adapter contributes no signal of its own, and therefore its test is a mating test: reference connectors mate through the adapter housing, and the inserted loss is recorded. A zirconia-sleeve adapter ought to add no more than 0.2 dB, and the mating must repeat that figure across cycles. Durability testing runs the mating hundreds of times and re-measures - a sleeve that wears loose announces itself as creeping loss. These figures, not the housing color, are what separates an adapter that serves for years from one that becomes the mystery fault.

Five decisions define the adapter housing order: the optical interface pairing must be aligned with the two sides of the mating, the mounting style must fit this adapter panel cutout, the polish color code must be aligned with the plant, the sleeve material must suit the behavior grade, and the count must cover the load-out plus spares. Getting all five right at order time is what turns a bag of couplers into a dependable panel. Where the pairing crosses connector families, the hybrid range covers the common conversions.

Each adapter is inspected before packing: the sleeve bore is checked for alignment and surface finish, the housing latches are cycled for positive engagement, and sample matings from every production lot are measured for insertion loss. Accessories are checked for fit against the adapters they serve.

Refer to this adapter by connector pairing, mounting style, polish grade and pack number of units when specifying a quotation. For configurations outside the listed options - mixed packs, panel hardware kits or project packing - send the specification with the request and the factory will make certain of the manufacturable specification. A clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
