Agilent AFBR-732B/BE and AFBR-
742B/BE Ultra Short Link Pluggable
Parallel Fiber Optic Modules,
Transmitter and Receiver
Data Sheet
Description
The AFBR-732B transmitter
and AFBR-742B receiver are
high performance fiber optic
modules for parallel optical
data communication
applications. These 12-channel
devices, operating up to 2.5Gbd
per channel, provide a cost
effective solution for short-
reach applications requiring up
to 30 Gb/s aggregate bandwidth.
These modules are designed to
operate on multimode fiber
systems at a nominal
wavelength of 850 nm. They
incorporate high performance,
highly reliable, short
wavelength optical devices
coupled with proven circuit
technology to provide long life
and consistent service.
The AFBR-732B transmitter
module incorporates a 12-
channel VCSEL (Vertical Cavity
Surface Emitting Laser) array
together with a custom 12-
channel laser driver integrated
circuit providing IEC-60825
and CDRH Class 1M laser eye
safety.
The AFBR-742B receiver
module contains a 12-channel
PIN photodiode array coupled
with a custom preamplifier /
post amplifier integrated
circuit.
Operating from a single +3.3 V
power supply, both modules
provide LVTTL or LVCMOS
control interfaces and Current
Mode Logic (CML) compatible
data interfaces to simplify
external circuitry.
The transmitter and receiver
devices are housed in MTP®/
MPO receptacled packages.
Electrical connections to the
devices are achieved by means
of a pluggable 10 x 10
connector array.

Notes:
1. Absolute Maximum Ratings are those values beyond which damage to the device may occur. See Reliability Data Sheet for specific reliability
performance.
2. Between Absolute Maximum Ratings and the Recommended Operating Conditions functional performance is not intended, device reliability is not
implied, and damage to the device may occur over an extended period of time.
3. This is the maximum voltage that can be applied across the Transmitter Differential Data Inputs without damaging the input circuit.
4. Case Temperature is measured as indicated in Figure 3.

Notes:
1. Recommended Operating Conditions are those values outside of which functional performance is not intended, device reliability is not implied, and
damage to the device may occur over an extended period of time. See Reliability Data Sheet for specific reliability performance.
2. Case Temperature is measured as indicated in Figure 3. A +55 °C, 1 m/s, parallel to the printed circuit board, air flow at the module or equivalent
cooling is required. See Figure 4.
3. The receiver has a lower cut off frequency near 100 kHz.
4. Data inputs are CML compatible. Coupling capacitors are required to block DC. ∆VDINP-P = ∆VDINH – ∆VDINL, where ∆VDINH = High State Differential
Data Input Voltage and ∆VDINL = Low State Differential Data Input Voltage.
5. Power Supply Noise is defined for the supply, VCC, over the frequency range from 500 Hz to 2500 MHz, with the recommended power supply filter in
place, at the supply side of the recommended filter. See Figures 5 and 6 for recommended power supply filters.

TX Enable. Active high. Internal pull-up High = VCSEL array is enabled if TX_DIS is inactive (Low). Low =
VCSEL array is off. TX_EN must be taken to a logic low state level (VOL) for 1 ms or longer.
TX Disable. Active high. Internal pull-down Low = VCSEL array is enabled if TX_EN is active (High). High =
VCSEL array is off. TX_DIS must be taken to a logic High state level (VOH) for 1 ms or longer.
Transmitter RESET- input. Active low. Internal pull-up. Low = Resets logic functions, clears FAULT- signal,
VCSEL array is off. high = Normal operation. See Figure 14.
Transmitter FAULT- output. Active low. Low (logic "0") results from a VCSEL over-current condition, out of
temperature range, or EEPROM calibration data corruption condition detected for any VCSEL. An asserted (logic
"0") FAULT- disables the VCSEL array and is cleared by RESET- or power cycling VCCT FAULT- is a single ended
LVTTL compatible output.

SD Signal Detect. Normal optical input levels to all channels results in a logic "1" output, VOH, asserted. Low input
optical levels to any channel results in a fault condition indicated by a logic "0" output, VOL, de-asserted. SD is a
single-ended LVTTL compatible output.
RX_EN
Receiver output enable. Active high (logic "1"), internal pull-up. Low (logic "0") = receiver outputs disabled, all
outputs are high (logic "1").
SQ_EN
Squelch enable input. Active high (logic "1"), internal pull-up. Low (logic "0") = squelch disabled. When SQ_EN
is high and SD is low, corresponding outputs are squelched.
