Compatibility with Fibre

Channel FC-0/1 Chip Sets

The HFBR-5301 and HFBR-5302

transceivers are compatible with

various manufacturers FC-0 and

FC-1 integrated circuits. Evalua-

tion boards, which include the

Hewlett-Packard transceivers, are

available from these manufactur-

ers. The Applications Engineering

group in the Hewlett- Packard

Optical Communication Division

is available to assist you with

implementation details.

Transceiver Optical Power

Budget vs. Link Length

Optical Power Budget (OPB) is

the available optical power for a

fiber optic link to accommodate

fiber cable losses plus losses due

to in-line connectors, splices,

optical switches, and to provide

margin for link aging and

unplanned losses due to cable

plant reconfiguration or repair.

Figure 4 illustrates the predicted

OPB associated with the two

transceivers specified in this data

sheet at the Beginning of Life

(BOL). These curves represent

the attenuation and chromatic

plus modal dispersion losses

associated with the 62.5/125 µm

and 50/125 µm fiber cables only.

Hewlett-Packard LED technology

has produced 1300 nm LED

devices with lower aging charac-

teristics than normally associated

with these technologies in the

industry. The industry convention

is 1.5 dB aging for 1300 nm

LEDs. The HP LEDs will experi-

ence less than 1 dB of aging over

normal commercial equipment

mission life periods. Contact your

Hewlett-Packard sales represen-

tative for additional details.

Figure 4 was generated with a

Hewlett-Packard fiber optic link

model containing the current

industry conventions for fiber

cable specifications and the Fibre

Channel optical parameters.

These parameters are reflected in

the specified performance of the

transceiver in this data sheet.

This same model has been used

extensively in the ANSI and IEEE

committees, including the ANSI

X3T9.5 committee, to establish

the optical performance require-

ments for various fiber-optic

interface standards. The cable

parameters used come from the

ISO/IEC JTC1/SC 25/WG3

Generic Cabling for Customer

Premises per DIS 11801

document and the EIA/TIA-568-A

Commercial Building Telecom-

munications Cabling Standard

per SP-2840.

Transceiver Signaling

Operating Rate Range and

BER Performance

For purposes of definition, the

symbol rate (Baud), also called

signaling rate, is the reciprocal of

the symbol time. Data rate (bits/

sec) is the symbol rate divided by

the encoding factor used to

encode the data (symbols/bit).

The specifications in this data

sheet have all been measured

using the standard Fibre Channel

symbol rates of 133 Mbd or

266 MBd.

The transceivers may be used for

other applications at signaling

rates different than specified in

this data sheet. Depending on the

actual signaling rate, there may

be some differences in optical
