Short Wavelength GBIC: HFBR-5601
Transmitter Section
The transmitter section consists of an 850 nm VCSEL in
an optical subassembly (OSA), which mates to the fiber
cable. The VCSEL OSA is driven by a custom, silicon
bipolar IC which converts differential logic signals into
an analog Laser Diode drive current.
Receiver Section
The receiver includes a GaAs PIN photodiode mounted
together with a custom, silicon bipolar transimpedance
preamplifier IC, in an OSA. The OSA interfaces to a
custom silicon bipolar circuit that provides post-
amplification and quantization. The post-amplifier
includes a Signal Detect circuit that provides TTL
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.

Eye Safety Design
The laser driver is designed to be Class 1 eye safe
(CDRH21 CFR(J), IEC 60825-1) under a single fault
condition. To be eye safe, only one of two results can
occur in the event of a single fault. The transmitter must
either maintain normal eye safe operation or the
transmitter should be disabled.
There are three key elements to the 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 dc regulation circuit
cannot maintain the preset bias conditions within
±20%, the transmitter will automatically be disabled.
