In order to avoid breaking the fiber and/or optical coupling degradation, NEC recommends the following handling precautions: 1. Do not make the fiber bend radius less than 30 mm (*3). 2. Do not bend the fiber within the 18 mm section from the module body (*4). 3. Do not stress the ferrule with a lateral force exceeding 500 g (*5). fiber 30 mm MIN (*3) (*1) 18 mm MIN (*4) ferrule (*5) (*2) module body EXCLUSIVE NORTH AMERICAN AGENT FOR RF, MICROWAVE & OPTOELECTRONIC SEMICONDUCTORS CALIFORNIA EASTERN LABORATORIES • Headquarters • 4590 Patrick Henry Drive • Santa Clara, CA 95054-1817 • (408) 988-3500 • Telex 34-6393 • FAX (408) 988-0279 24-Hour Fax-On-Demand: 800-390-3232 (U.S. and Canada only) • Internet: http://WWW.CEL.COM 9/99 DATA SUBJECT TO CHANGE WITHOUT NOTICE
