Description
General
The HFBR-5208M (multimode
transceiver) and HFCT-5208M
(single-mode transceiver) from
Agilent allow the system designer
to implement a range of solutions
for ATM/SONET STS-12/SDH
STM-4 applications.
The overall Agilent transceiver
consists of three sections: the
transmitter and receiver optical
subassemblies, an electrical
subassembly and the mezzanine
package housing which
incorporates a duplex SC
connector receptacle.
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
PECL logic signals (ECL
referenced to a +5 V supply) into
an analog LED/laser drive current.
Applications
HFBR-5208M:
• General purpose low-cost MMF
links at 155 to 650 Mb/s
