Multimode Small Form Factor (SFF) Transceivers for ATM, FDDI,
Fast Ethernet and SONET OC-3/SDH STM-1 with LC connector
Data Sheet
Description
The HFBR-5961xxZ transceiver from Avago provides 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 is supplied in the industry standard 2 x
5 DIP style with an LC fiber connector interface with an
external connector shield.
Transmitter Section
The transmitter section of the HFBR-5961xxZ 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 differ-
ential 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-5961xxZ utilizes an
InGaAs PIN photodiode coupled to a custom silicon
transimpedance preamplifier IC.It is packaged in the
optical subassembly 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 Signal Detect
function. The Data output is differential. The Signal
Detect output is single ended. Both Data and Signal
Detect outputs are PECL compatible, ECL referenced
(shifted) to a +3.3 V power supply.The receiver
outputs, Data Output and Data Out Bar, are squelched
at Signal Detect deassert.That is, when the light input
power decreases to a typical -38 dBm or less, the Signal
Detect deasserts, ie. the Signal Detect output goes to a
PECL low state. This forces the receiver outputs, Data
Out and Data Out Bar to go steady PECL levels high and
low respectively.
