Description
The LST range of products
includes a wide variety of
connectorized ELED emitters for
both single mode and multimode
operation. The products have
been developed for low cost and
wide operating temperature
applications such as telecom FITL
and datacom FDDI LANS. Vari-
ants are available in industry
standard connector types with a
selection of mounting flange
options.
The product range features a high
reliability ridge waveguide ELED
manufactured using our MOVPE
process. The construction of the
products includes a hermetically
sealed ELED and is designed to be
compatible with the environmen-
tal requirements of the Bellcore
TA-TSY-000983 document.
Applications
• Optical Data Communication
Transmitters
• E-O Convertors
• LANS
• FDDI Networks
• FITL
• Single Mode: LST0400
Multimode: LST0500

Absolute Maximum Ratings
Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided each
limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting
values of more than one parameter can be applied to the product at the same time.
