NX5521

LASER DIODE NX5521 Series 1 550 nm FOR FTTH InGaAsP MQW-FP LASER DIODE DESCRIPTION The NX5521 Series is a 1 550 nm Multiple Quantum Well (MQW) structured Fabry-Perot (FP) laser diodes with InGaAs monitor PIN-PD. These devices are designed and ideal for Fiber To The Home (FTTH). APPLICATION 155 Mbps FTTH P2P (Fiber To The Home Point to Point) system FEATURES Optical output power Low threshold current Differential efficiency InGaAs monitor PIN-PD CAN package Fiber coupling point Po = 5.0 mW lth = 8 mA ηd = 0.25 W/A Wide operating temperature range TC = −40 to +85°C φ 5.6 mm 5.8 mm Document No. PL10754EJ01V0DS (1st edition) Date Published April 2009 NS NX5521 Series PACKAGE DIMENSIONS (UNIT: mm) φ 5.6+0.00 –0.03 (φ 4.2)*2 (φ 3.55)*2 1.0±0.1 BOTTOM VIEW 1 2 3 4 (0.4)*2 φ1.5 110°±2° (0.4) *2 Fiber Coupling Point *1 5.80±0.05 ∆ x = ±300 µ m ∆ y = ±300 µ m 15.0±1.0 1.2±0.1 3.90±0.2 PIN CONNECTIONS NX5521EH 1 (Case) NX5521EK 1 (Case) LD 2 4 4 PD 3 Reference Plane 2 4– φ 0.45 PD 3 LD φ 2.0 *1 Recommendation of Fiber Coupling Conditions Fiber : SMF with 8 degree angle-polished ferrule Fiber coupling distance : 5.80±0.05 mm from reference plane.
