• Full Compliance with ATM
Forum UNI SONET OC-3
Multimode Fiber Physical
Layer Specification
• Multisourced 1 x 9 Package
Style with Choice of Duplex
SC or Duplex ST* Receptacle
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.
• Wave Solder and Aqueous
Wash Process Compatibility
• Manufactured in an ISO 9002
Certified Facility
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.
Applications
• Multimode Fiber ATM
Backbone Links
• Multimode Fiber ATM Wiring
Closet to Desktop Links
• ATM 155 Mbps/194 MBd
Encoded Links (available
upon special request)
Selected versions of these
transceivers may be used to
implement the ATM Forum UNI
Physical Layer Interface at the
155 Mbps/194 MBd rate.
Transmitter Sections
The transmitter sections of the
HFBR-5204 and HFBR-5205
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 +5 Volt supply, into
an analog LED drive current.
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
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.
SONET OC-3 (SDH STM-1) physical
layers for ATM and other services.
