Description
The HFBR-5800 family of
transceivers from Agilent
provide the system designer
with products to implement a
range of solutions for
multimode fiber SONET OC-3
(SDH STM-1) physical layers
for ATM and other services.
The transceivers are all
supplied in the industry
standard 1 x 9 SIP package
style with either a duplex SC
or a duplex ST* connector
interface.
ATM 2 km Backbone Links
The HFBR-5805/-5805T are
1300 nm products with optical
performance compliant with
the SONET STS-3c (OC-3)
Physical Layer Interface
Specification. This physical
layer is defined in the ATM
Forum User-Network Interface
(UNI) Specification Version 3.0.
This document references the
ANSI T1E1.2 specification for
the details of the interface for
2 km multimode fiber
backbone links.
The ATM 100 Mb/s-125 MBd
Physical Layer interface is best
implemented with the HFBR-
5803 family of Fast Ethernet
and FDDI Transceivers which
are specified for use in this
4B/5B encoded physical layer
per the FDDI PMD standard.
Transmitter Sections
The transmitter section of the
HFBR-5803 and HFBR-5805
series utilize 1300 nm InGaAsP
LEDs. These LEDs are
packaged in the optical
subassembly portion of the
transmitter section. They are
driven by a custom silicon IC
which converts differential
PECL logic signals, ECL
referenced (shifted) to a +3.3 V
or +5.0 V supply, into an
analog LED drive current.
Receiver Sections
The receiver section of the
HFBR-5803 and HFBR-5805
series utilize InGaAs PIN
photodiodes coupled to a
custom silicon transimpedance
preamplifier IC. These are
packaged in the optical
subassembly portion of the
receiver.
These PIN/preamplifier
combinations are 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 dif-
ferential. The signal detect
output is single-ended. Both
data and signal detect outputs
are PECL compatible, ECL
referenced (shifted) to a 3.3 V
or +5.0 V power supply.
