• Manufacturer Part Number: HFBR-5106T
• Description: 100VG-AnyLAN Multimode Fiber Transceivers in Low Cost 1x9 Package Style
• Manufacturer: Agilent(Hewlett-Packard)

The HP 1300 nm transmitters are
allowed to generate the worst
case Active Output jitter shown in
Table 27 of section 18.9 when
driven by circuits optimized for
these link applications. The
Active Output Specifications of
the 100VG-AnyLAN standard are
met by the HFBR-5106.
The HP 1300 nm receivers
tolerate the worst case input
optical response time and
systematic jitter shown in
Table 27 of Section 18.9. The
Active Input Specification of the
IEEE 802.12 100VG-AnyLAN
standard are met by the
HBFR-5106.
The jitter specifications stated in
the 1300 nm transceiver
specification tables are derived
from the values in Table 27 of
section 18.9 of the IEEE 802.12
specification. They represent the
worst case jitter contributions
from the transceiver meeting the
overall system jitter in Annex E.
In practice the typical jitter
contribution of the HP transceiv-
ers is well below these maximum
allowed values.
Recommended Handling
Precautions
It is advised that normal static
precautions be taken in the
handling and assembly of these
transceivers to prevent damage
which may be induced by
electrostatic discharge (ESD).
The HFBR-510X series of
transceivers are certified as
Mil-Std-883C Method 3015.4
Class 1 products.
Care should be used to avoid
shorting the receiver data or
signal detect outputs directly to

ground without proper current
limiting impedance.
Solder and Wash Process
Compatibility
The transceivers are delivered
with a protective process plug
inserted into the duplex SC
connector receptacle. This
process plug protects the optical
subassemblies during wave solder
and aqueous wash processing and
acts as a dust cover during
shipping. These transceivers are
compatible with either industry
standard wave or hand soldering
processes.

Shipping Container
The transceiver is packaged in a
shipping container designed to
protect it from mechanical and
ESD damage during shipment or
storage.
Board Layout –
Decoupling Circuit and
Ground Planes
It is important to take care in the
layout of your circuit board to
achieve optimum performance
from these transceivers. Figure 7
provides a good example of a
schematic for a power supply
decoupling circuit that works
