This simplex single-mode pigtail combines a compact LC/APC connector with a semi-tight 0.9 mm buffer that strips long sections in a single cut. The 8-degree angled polish keeps reflections low for PON and RF video links. Bend-insensitive G.657.A1 fiber handles the tight paths inside splitter modules and FTTH boxes.
Its yellow OFNR riser-rated buffer flags it as single-mode fiber. It comes in 1 m and 3 m lengths. It's a quick, clean way to bring a single APC strand online in high-density PON hardware. FTTH crews keep it on hand for fast, low-reflection single-strand turn-ups.
Quick Prep for Single Turn-Ups
FTTH crews often terminate one fiber at a time as customers sign up. The semi-tight buffer strips 10 cm or more in one cut, with no gel or powder. That speeds up each turn-up and limits handling of bare glass.
Measuring Return Loss
Return loss tells you how much light reflects back toward the source. Many OTDRs and dedicated return loss meters can measure it at 1310 and 1550 nm. An APC connection in good condition typically reads 60 dB or better. A noticeably lower reading usually points to a dirty or damaged end face.
LC/APC Density
The LC body's 1.25 mm ferrule takes half the space of SC. Many modern splitter modules and ODF panels use LC/APC to fit more customers in the same rack space.
Bend-Insensitive Glass
G.657.A1 supports a 10 mm minimum bend radius. It matches the mode field of G.652.D drop and feeder cable, so splices stay low-loss.
Choosing 1 m or 3 m
Pick 1 m for compact customer boxes and small splitter enclosures. Choose 3 m for hub cabinets and OLT frames, where the fiber needs room to reach a splice tray.
Fitting Into Splitter Modules
Many compact splitter modules accept LC/APC connections on the front panel. This pigtail can land a feeder or distribution fiber directly on those ports. That keeps the hub layout neat and saves rack space.

Inspect Every Time
The angled face collects dust as easily as any other. Scope and clean before each connection, following IEC 61300-3-35 criteria. Replace the dust cap whenever the port sits empty, even briefly.
