Transmitter Section
•
The transmitter section of the
HFBR-5208M consists of a 1300 nm
LED in an optical subassembly
(OSA) which mates to the multi-
mode fiber cable. The HFCT-5208M
incorporates a 1300 nm Fabry
Perot (FP) laser in the optical
subassembly. In addition, this
package has been designed to be
compliant with IEC 825 eye-safety
requirements under any single
fault condition. The OSA’s are
driven by a custom, silicon bipolar
IC which converts differential
