WTIH1514-S0080 Datasheet, PDF (1/2 Pages) OPLINK Communications Inc. – 1480/1550(1585)nm WDM/ Tap Couper/ Isolator Hybrid Combination

1480/1550(1585)nm WDM/ Tap Couper/
Isolator Hybrid Combination
WTIH1514 Series
Product Description
Oplink’s WTIH is a combination of a wavelength division multiplexer, tap cou-
pler and an isolator in a compact package.This product has an extremely low
insertion loss, and a very stable tap-coupling ratio. Fiber optic amplification is
the ideal application for this product.
Oplink can provide customized designs to meet specialized feature applica-
tions. Also, Oplink offers modular assemblies that integrate other compo-
nents to form a full function module or subsystem.
