SC Fast Connectors KW-01 — SC/APC & SC/UPC Field Assembly
Field assembly SC connectors in APC and UPC — a whole family of housings from 45 to 60 mm, terminated with the length-setting jig in about a minute.
Typical work: FTTH drop termination at the ONT — GPON (APC) and general single-mode (UPC); Field repairs and re-terminations without a fusion splicer; Installer standardisation — one housing family across every crew.

KW-01 key features
- Not one connector but the family: SC fast connectors in lengths from 45 to 60 mm, in standard, nut-type, gland-type and drawer-type housings
- SC/APC in green for GPON and CATV drops, SC/UPC in blue for general single-mode work
- Pre-polished ceramic ferrule with a mechanical splice inside — strip, cleave, insert, lock; no epoxy, no polishing, no splicer
- Every version works with the length-setting jig: it fixes the strip length, peels the coating and opens the cover, so field results stop depending on the installer's hand
- Insertion loss typical ≤0.3 dB (max ≤0.5 dB); return loss ≥50 dB UPC and ≥55 dB APC; re-terminable when a cleave goes wrong

How It Works — pick the housing, the optics stay the same
Inside each KW-01 sits a factory-polished fiber stub waiting in a precision V-groove with index-matching gel. The installer strips and cleaves the drop cable, slides it in until the ends meet, and locks the clamp. What changes across the family is the housing around that joint: short 45 mm bodies for tight closures, 60 mm bodies for gloved hands, nut-type tails that screw down on round cable, gland types, drawer types whose inner carrier slides out for assembly, and versions that take the flat drop cable horizontally or vertically.
The shared jig is the quiet professional detail. It sets the exact strip and cleave length for the housing, helps peel the 0.9 mm coating, and its corner opens the connector's flip cover — the three places field terminations usually go wrong, handled by one small tool that ships with the connectors.
Ordering note: tell us the polish (APC or UPC), the cable — flat drop 2×3.0 mm or 1.6×2.0 mm, or round Ø0.9 / 2.0 / 3.0 mm — and the housing style or length you standardise on, and the connectors arrive matched, in bulk or in your packaging.

Questions about the KW-01
Can the KW-01 carry our own brand?
Private labeling is made to your requirements and confirmed per order — labels with your logo, part numbers and barcodes on the tools, the inner boxes and the outer cartons, ready for your warehouse. The products most often labeled are the K-35 cleaver, the KS-1 Kevlar shears and the K-870 stripper.
Can we order a small lot, unbranded?
Yes. Neutral stock is held for the core range: small lots are welcome, you can mix models in one shipment, and restock as you sell. Prices are on request — EXW factory pricing.
