SERIES

FEATURES

• SMALL DARK CURRENT:

ID = 5 nA

• HIGH QUANTUM EFFICIENCY:

η = 90% at λ = 1300 nm, M = 1

η = 77% at λ = 1550 nm, M = 1

• HIGH SPEED RESPONSE:

fc = 2.5 GHz at M = 10

• DETECTING AREA SIZE:

φ50 µm

• COAXIAL MODULE WITH MULTIMODE FIBER

(GI-50/125)

• NDL5521P1 AND NDL5521P2 HAVE A FLANGE

The NDL5521P Series are InGaAs avalanche photo diode

modules with multimode fiber.They are designed for 2.5 Gb/s

optical fiber communication systems and cover the wave-

length range between 1000 and 1600 nm with high efficiency.

These modules are also available with FC-PC connector and

SC-PC connector.
