10 km Link Support

As for the receiver section, it is

internally ac-coupled between

the preamplifier and the post-

amplifier stages. The actual Data

and Data-bar outputs of the post-

amplifier are dc-coupled to their

respective output pins (pins 4, 5).

Signal Detect is a single-ended,

+3.3 V TTL output signal that is

dc-coupled to pin 3 of the

for signal return current. This

recommendation is in keeping

with good high frequency board

layout practices.

As well as complying with the LX

5 km standard, the HFCT-5912E

specification provides additional

margin allowing for a 10 km

Gigabit Ethernet link on single

mode fiber. This is accomplished

by limiting the spectral width and

center wavelength range of the

transmitter while increasing the

output optical power and

For an optical transmitter device

to be eye-safe in the event of a

single fault failure, the transmit-

ter must either maintain eye-safe

operation or be disabled.

apertures. Careful attention must

be paid to the locations of high-

speed clocks or gigabit circuitry

with respect to these apertures.

While experimental measurements

and experiences do not indicate

any specific transceiver emissions

issues, Agilent recognizes that

the transceiver aperture is often a

weak link in system enclosure

integrity and has designed the

modules to minimize emissions

and if necessary, contain the

internal system emissions by

shielding the aperture.

In the HFBR-5912E there are

three key elements to the laser

driver safety circuitry: a monitor

diode, a window detector circuit,

and direct control of the laser

bias. The window detection

circuit monitors the average

optical power using the monitor

diode. If a fault occurs such that

the transmitter dc regulation

circuit cannot maintain the

preset bias conditions for the

laser emitter within 20ꢀ, the

transmitter will automatically be

disabled. Once this has occurred,

an electrical power reset or

toggling the transmit disable will

allow an attempted turn-on of the

transmitter. If fault remains the

transmitter will stay disabled.

Electromagnetic

Interference (EMI)

One of a circuit board designer’s

foremost concerns is the control

of electromagnetic emissions

from electronic equipment.

Success in controlling generated

Electromagnetic Interference

(EMI) enables the designer to

pass a governmental agency’s

EMI regulatory standard and

more importantly, it reduces the

possibility of interference to

neighboring equipment. Agilent

has designed the HFBR/HFCT-

5912E to provide excellent EMI

performance. The EMI

performance of a chassis is

dependent on physical design and

features which help improve EMI

suppression. Agilent encourages

using standard RF suppression

practices and avoiding poorly

EMI-sealed enclosures.

To that end, Agilent’s gigabit

MT-RJ transceivers (HFCT-5912E

and HFBR-5912E) have nose

shields which provide a

convenient chassis connection to

the nose of the transceiver. This

nose shield improves system EMI

performance by closing off the

MT-RJ aperture. Localized

shielding is also improved by

tying the four metal housing

package grounding tabs to signal

ground on the PCB. Though not

obvious by inspection, the nose

shield and metal housing are

electrically separated for

customers who do not wish to

directly tie chassis and signal

grounds together. The

The HFCT-5912E utilizes an

optical subassembly consisting of

a short piece of single mode fiber

along with a current limiting

circuit to guarantee eye-safety. It

is intrinsically eye safe and does

not require shut down circuitry.

Radiated Emissions for the

HFBR-5912E and HFCT-5912E

have been tested successfully in

several environments. While this

number is important for system

designers in terms of emissions

levels inside a system, Agilent

recognizes that the performance

of most interest to our customers

is the emissions levels, which

could be expected to radiate to

the outside world from inside a

typical system. In their

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in isolation, all

other parameters having values within the recommended operating conditions. It should not be assumed that limiting values of more than one

parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for extended periods can adversely affect

device reliability.

1. The maximum Optical Output Power complies with the IEEE 802.3z specification, and is Class 1 laser eye safe.

2. Optical Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the

low (“0”) state. The transmitter is driven with a Gigabit Ethernet 1250 MBd 8B/10B encoded serial data pattern. This Optical

Extinction Ratio is expressed in decibels (dB) by the relationship 10log(Phigh avg/Plow avg).

3. These are unfiltered 20-80ꢀ values.

4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 1). The characteristics include rise time,

fall time, pulse overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the

receiver sensitivity. These parameters are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The

output optical waveform complies with the requirements of the eye mask discussed in section 38.6.5 and Fig. 38-2 of IEEE 802.3z.

5. CPR is measured in accordance with EIA/TIA-526-14A as referenced in 802.3z, section 38.6.10.

6. TP refers to the compliance point specified in 802.3z, section 38.2.1.

7. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.

8. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The

conformance test signal is conditioned by applying deterministic jitter and intersymbol interference.

Notes:

1. The maximum Optical Output Power complies with the IEEE 802.3z specification, and is class 1 laser eye safe.

2. Optical Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the

low (“0”) state. The transmitter is driven with a Gigabit Ethernet 1250 MBd 8B/10B encoded serial data pattern. This Optical

Extinction Ratio is expressed in decibels (dB) by the relationship 10log(Phigh avg /Plow avg ).

3. These are unfiltered 20-80ꢀ values.

4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 1). The characteristics include rise time,

fall time, pulse overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the

receiver sensitivity. These parameters are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The

output optical waveform complies with the requirements of the eye mask discussed in section 38.6.5 and Fig. 38-2 of IEEE 802.3z.

5. TP refers to the compliance point specified in 802.3z, section 38.2.1.

6. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.

7. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The

conformance test signal is conditioned by applying deterministic jitter and intersymbol interference.

8. The stressed receiver jitter is measured using the conformance test signal defined in 802.3z, section 38.6.11 and set to an average

optical power 0.5 dB greater than the specified stressed receive sensitivity.

9. The 3 dB electrical bandwidth of the receiver is measured using the technique outlined in 802.3z, section 38.6.12.

10. Return loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.

NOTES:

USE SURFACE-MOUNT COMPONENTS FOR OPTIMUM HIGH-FREQUENCY PERFORMANCE.

USE 50 MICROSTRIP OR STRIPLINE FOR SIGNAL PATHS.

LOCATE 50 TERMINATIONS AT THE INPUTS OF RECEIVING UNITS.

* IN ORDER TO ELIMINATE REQUIRED EXTERNAL PASSIVE COMPONENTS, AGILENT HAS INCLUDED THE EQUIVALENT OF RESISTORS R5 - R8 AND CAPACITORS

C5 AND C6 WITHIN THE MODULE. R5 - R8, C5 AND C6 ARE INCLUDED AS PART OF THE APPLICATION CIRCUIT TO ACCOMMODATE OTHER TRANSCEIVER

VENDORS' MODULES. THE HFBR/HFCT-5912E WILL OPERATE IN BOTH CONFIGURATIONS.

**C8 IS A RECOMMENDED BYPASS CAPACITOR FOR ADDITIONAL LOW FREQUENCY NOISE FILTERING.

THE SIGNAL DETECT OUTPUT ON THE HFBR-5912E CONTAINS AN INTERNAL 1.8 k PULL UP RESISTOR. THE OUTPUT STAGE ON THE HFCT-5912E IS A PUSH

PULL CONFIGURATION AND THEREFORE DOES NOT REQUIRE AN EXTERNAL PULL UP RESISTOR.
