Applications & Compatibility
Why Choose PGS & FAQs
Why does APC matter for FTTH specifically?
PON networks require 55 dB or better return loss to perform correctly — the angled polish is what achieves that. UPC's flat polish won't meet this spec.
What tools are needed to install it?
A fibre stripper and a fibre cleaver only — no fusion splicer, polishing equipment, or epoxy.
Can it be reused?
Most are single-use. Some models are re-openable, but optical performance after reopening isn't guaranteed — treat as single-use for permanent installations.
Is this sold individually or in bulk?
Both — buy a single connector for a small job, or a box of 10 at a discounted per-unit price for larger orders.
