FEATURES
DESCRIPTION
• OPTICAL OUTPUT POWER:
Pf = 0.6 mW
NEC's NX7315UA is a 1310 nm Multiple Quantum Well
(MQW) structured Fabry-Perot (FP) laser diode transmitter
optical subassembly (TOSA) with InGaAs monitor PIN-PD in
a receptacle type package designed for LC type SFF/SFP
transceiver modules. These devices are ideal for Synchronous
Digital Hierarchy (SDH) systems, STM-16 Intraoffice I-16 ITU-T
recommendations, and SONET OC-48(SR).
• LOW THRESHOLD CURRENT
Ith = 8 mA TYP @ TC = 25°C
• WIDE OPERATING TEMPERATURE RANGE:
-40 to +85°C
• InGaAs MONITOR PIN-PD
• SMALL PACKAGE
ø3.8 mm (Total length 12.0 mm MAX
• BASED ON Telcordia Reliability GR-468-CORE

Subject: Compliance with EU Directives
CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant
with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous
Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive
2003/11/EC Restriction on Penta and Octa BDE.
CEL Pb-free products have the same base part number with a suffix added. The suffix –A indicates
that the device is Pb-free. The –AZ suffix is used to designate devices containing Pb which are
exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals.
All devices with these suffixes meet the requirements of the RoHS directive.
This status is based on CEL’s understanding of the EU Directives and knowledge of the materials that
go into its products as of the date of disclosure of this information.
