12-Strand SC/UPC Single-Mode Fiber Pigtail, No Jacket, 2 Meter (PGUSC12-SM)

This is a 12-fiber single-mode SC/UPC pigtail, 2 meters long, with no outer jacket. Each of the 12 OS2 fibers has a factory-terminated and tested SC/UPC connector on one end and bare fiber on the other for fusion or mechanical splicing. Because there's no jacket, the 12 strands fan out loose from the connector end, which makes them easy to route to a splice tray and lets them bend tighter inside a crowded enclosure than a jacketed fan-out would. The SC end plugs straight into an adapter panel, so a 12-fiber cable spliced to this pigtail becomes 12 SC ports in one tray. It's sold individually, as one 12-strand pigtail. For the APC version, the PGUSC12-SMA; for LC/UPC, the PGULC12-SM; for the enclosure, the RMFP rack-mount panels and the WMFP wall-mount boxes; for the SC adapters and the fusion splicer, see the fiber collections.

Features

• 12 fibers, SC/UPC. Single-mode OS2, 9/125 µm, with a UPC connector on each strand.
• Unjacketed fan-out. The 12 strands route loose to a splice tray and bend tighter than a jacketed cable.
• 250 µm buffer. No outer jacket.
• Factory-tested. Low insertion loss and return loss.
• For fusion or mechanical splicing. Bare fiber at the splice end.
• 2 meter length.
• Sold individually. One 12-strand pigtail.

Where It Fits

It suits enterprise and campus backbones terminating single-mode fiber in a rack panel, where SC is the port on the panel and on the older equipment. It suits fiber distribution units and optical distribution frames in a telecom room, and splice trays in a wall-mount box. Crews splicing a 12-fiber cable out to SC ports in one tray use it, and so do installers extending an existing SC plant rather than converting it to LC. A fiber distribution box in a riser closet is a candidate. It goes with the single-mode bulk fiber, the SC adapters, the splice trays and sleeves, and the fusion splicer from the fiber collections. For a PON or an RF-over-glass plant that specifies APC, the PGUSC12-SMA. For LC/UPC instead, the PGULC12-SM. For a jacketed LC version, the PGTLC12-SM. For rack-mount splice panels, the RMFP-016 and RMFP-018. For a wall-mount box, the WMFP-011. For the SC patch cords on the other side of the panel, the SCSCSM, and for SC to LC, the LCSCSM.

Good to Know

UPC is the flat-polish connector, usually blue, and it mates with UPC adapters and UPC cords; don't put it against an APC adapter or an APC cord, since the angled face meets the flat one with an air gap and the loss goes up. If the plant is a PON or an RF-over-glass system that calls for APC, the green PGUSC12-SMA is the right pigtail. The strands are 250 µm, which is the bare coated fiber with no 900 µm tight buffer over it, so handle them as you would the fibers inside a loose-tube cable: they belong in a splice tray with 250 µm holders or in a tray that takes a protection sleeve, and they need to be dressed carefully, since a 250 µm fiber has no extra padding against a sharp edge. Strip the coating back to bare glass, cleave, splice to the incoming cable, and seat the sleeve in the tray. With no jacket there's no strength member, so the pigtail is for inside an enclosure only, never for a run between boxes, and the bundle wants to be tied loosely to the tray so the connectors aren't carrying the fibers' weight. Keep the bend radius generous even though the bare strands will tolerate tighter curves than a jacketed cable; the splice point is where a hard bend shows up as loss. Splice in the standard color sequence and match it to the incoming cable's buffer tubes so the as-built is honest. Clean and inspect every SC connector before it goes into an adapter, and keep the dust caps on until then. If 2 meters is more than the tray needs, coil the excess in the slack ring rather than cutting it short.
