Data Sheet
Description
The HFBR-57E5APZ Small Form-Factor Pluggable LC trans-
ceiver gives the system designer a product to implement
FDDI/Fast Ethernet network with DMI and SONET OC-3
(SDH STM-1) physical layers for ATM and other services.
As an enhancement to the conventional SFP interface
defined in SFF-8074i, the HFBR-57E5APZ is compatible
to SFF-8472 (digital diagnostic interface for optical trans-
ceivers). Using the 2-wire serial interface defined in the
SFF-8472 MSA, the HFBR-57E5APZ provides real-time
information on temperature, LED bias current, LED
average output power and receiver average input power.
The interface also adds the ability to monitor the Receiver
Loss of Signal (RX_LOS).
Transmitter
The transmitter contains a 1310 nm InGaAsP LED. The
LED is packaged in the optical subassembly of the trans-
mitter. It is driven by an integrated circuit which converts
differential PECL logic signals into an analog LED drive
current. This current is monitored by the digital diagnostic
interface. The transmitter light output power is inferred
from this information.
Receiver
The receiver utilizes an InGaAs PIN photodiode coupled
to a transimpedance preamplifier IC. It is packaged in the
optical subassembly of the receiver. The PIN/preamplifier
combination is connected to a quantizer IC which provides
the final pulse shaping for data output. The data output is
differential LVPECL. The quantizer IC has a loss of signal
(LOS) detection circuit and has an open collector logic
high output signal in the absence of a usable input optical
signal. This LOS output is +3.3 V TTL as per SFF-8074i.
The PIN photodiode average current is monitored by the
digital diagnostic interface as a measure for input optical
power.
