Data Sheet
Description
The HFBR-57E0 Small Form Factor Pluggable LC trans-
ceivers provide the system designer with a product to
implement a range of solutions for multimode fiber Fast
Ethernet and SONET OC-3 (SDH STM-1) physical layers for
ATM and other services.
This transceiver operates at a nominal wavelength of
1300 nm with an LC fiber connector interface with an
external connector shield (HFBR-57E0).
Transmitter Section
The transmitter section of the HFBR-57E0 utilizes a 1300
nm InGaAsP LED. This LED is packaged in the optical
subassembly portion of the transmitter section. It is
driven by a custom silicon IC which converts differential
PECL logic signals, ECL referenced (shifted) to a +3.3 V
supply, into an analog LED drive current.
Receiver Section
The receiver section of the HFBR-57E0 utilizes an InGaAs
PIN photodiode coupled to a custom silicon transimped-
ance preamplifier IC. It is packaged in the optical subas-
sembly portion of the receiver.
This PIN/preamplifier combination is coupled to a custom
quantizer IC which provides the final pulse shaping for
the logic output and the Loss of Signal (LOS) function.
The data output is differential. The data output is PECL
compatible, ECL referenced (shifted) to a +3.3 V power
supply. This circuit also includes a loss of signal (LOS)
detection circuit which provides an open collector logic
high output in the absence of a usable input optical sig-
nal. The LOS output is +3.3 V TTL.
