Technical Data
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.
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.
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.
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 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.
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.
The HFBR-5200 family of trans-
ceivers from Hewlett-Packard
provide the system designer with
products to implement a range of
solutions for multimode fiber
SONET OC-3 (SDH STM-1)
The transmitter sections of the
HFBR-5204 and HFBR-5205
series utilize 1300 nm InGaAsP
LEDs and the HFBR-5203 series
