Name: Santec OTF-350 파장가변 필터 Tunable Filter
Brand: 01. Spectroscopy

Description

The OTF-350 is a manual tunable optical filter covering 1530 to 1610 nm with selectable bandwidth options (0.1–15 nm wide type, 0.2–10 nm normal type). With low insertion loss, high return loss (> 40 dB) and low PDL (< 0.25 dB), it is a cost-effective passive filtering solution for fiber optic applications.

OTF-350은 1530~1610 nm를 가변 대역폭 옵션(와이드 타입 0.1~15 nm, 일반 타입 0.2~10 nm)으로 커버하는 수동 파장가변 광 필터입니다. 낮은 삽입 손실, 높은 반사 손실(> 40 dB), 낮은 PDL(< 0.25 dB)로 광섬유 응용을 위한 경제적인 수동 필터링 솔루션입니다.
