Description
The HFBR-5200 family of trans-
ceivers from Agilent Technologies
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.
These transceivers are all
supplied in the new industry
standard 1x9 SIP package style
with either a duplex SC or a
duplex ST* connector interface.
ATM 2000 m Backbone Links
The HFBR-5205/-5205T 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 Inter-
face (UNI) Specification Version
3.0. This document references the
ANSI T1E1.2 specification for the
details of the interface for 2000
meter multimode fiber backbone
links.
Selected versions of these
transceivers may be used to
implement the ATM Forum UNI
Physical Layer Interface at the
155 Mbps/194 MBd rate.
The ATM 100 Mbps/125 MBd
Physical Layer interface is best
implemented with the HFBR-5100
family of FDDI Transceivers
which are specified for use in this
4B/5B encoded physical layer per
the FDDI PMD standard.
ATM 500 m Backbone and
Desktop Links
The HFBR-5204/-5204T are 1300
nm products which are similar to
the HFBR-5205/5205T except
that they are intended to provide
a lower cost SONET OC-3 link to
distances up to 500 meters in
62.5/125 µm multimode fiber
optic cables.
Very Low Cost ATM 300 m
Desktop Links
The HFBR-5203/-5203T are very
low cost 800 nm alternatives to
the HFBR-5204/-5204T for
SONET OC-3 links to distances up
to 300 meters in 62.5/125 µm
multimode fiber optic cables.
Transmitter Sections
The transmitter sections of the
HFBR-5204 and HFBR-5205
series utilize 1300 nm InGaAsP
LEDs and the HFBR-5203 series
