DESCRIPTION
NEC's NX7314UA is a 1310 nm Multiple Quantum Well (MQW) structured Fabry-Perot (FP) laser diode transmitter optical subassembly (TOSA) with InGaAs monitor in a receptacle type package designed for LC type SFF/SFP transceiver modules. This device is ideal for Synchronous Digital Hierarchy (SDH) systems, STM-1 LONG HAUL L-1.1, ITU-T recommendations, and SONET OC-3(LR).

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.
