PON typically operates as point-to-point but can support a 1x16 split; which PON type matches this description?

Explanation:
The key idea here is how a PON divides a single fiber among multiple subscribers using a splitter, and which technology is commonly described in that context. A 1x16 split means one optical signal from the central office is divided to serve 16 different user units, sharing the same fiber component. The Ethernet PON (EPON) is the straightest fit for this scenario because it is the widely adopted, Ethernet-based PON approach that is routinely deployed with passive splitters in configurations like 1x16 (and larger) to provide multi-user access over a single fiber. EPON uses standard Ethernet framing and a simple MAC-layer sharing mechanism that works well with such a splitter arrangement, making it the most typical match for a range of split ratios including 1x16. The other options describe different PON flavors that either emphasize higher split ratios or different paradigms. GPON can also use splitters but is commonly associated with larger splits up to 1:128 and more complex provisioning. APON is an older ATM-based PON, and WDM-PON tends toward point-to-point channels using wavelength-division multiplexing rather than shared splitting.
