Which statement about Planar splitters for 1x16 configurations is accurate?

• A. Planar splitters are more precise for 1x16
• B. Planar splitters are more precise for 1x8
• C. Planar splitters cannot be used for 1x16
• D. Planar splitters are up to 1x32

Answer: (A)

Planar splitters distribute light through an integrated network on a single chip, so every output path is created with the same fabrication process, leading to very tight channel-to-channel uniformity. In a 1-by-16 configuration, that uniformity across 16 outputs is particularly well controlled, giving you a more precise and balanced split across all ports than you typically get with fewer outputs. Planar splitters do support a 1-by-16 arrangement and are also available in larger sizes (up to 1-by-32), so the statement about higher precision specifically for 1-by-16 reflects the strong uniformity these devices can achieve in that configuration.
