HFBR-14x2Z/14x4Z Low-Cost High-Speed Transmitters Housed Product
Description
The HFBR-14xxZ fiber optic transmitter contains an 820
nm AlGaAs emitter capable of efficiently launching opti-
cal power into four different optical fiber sizes: 50/125
μm, 62.5/125 μm, 100/140 μm, and 200 μm HCS®. This
allows the designer flexibility in choosing the fiber size.
The HFBR-14xxZ is designed to operate with the Avago
Technologies HFBR-24xxZ fiber optic receivers.
The HFBR-14xxZ transmitter’s high coupling efficiency
allows the emitter to be driven at low current levels
resulting in low power consumption and increased reli-
ability of the transmitter. The HFBR-14x4Z high power
transmitter is optimized for small size fiber and typically
can launch -15.8 dBm optical power at 60 mA into 50/125
μm fiber and -12 dBm into 62.5/125 μm fiber. The HFBR-
14x2Z standard transmitter typically can launch -12 dBm
of optical power at 60 mA into 100/140 μm fiber cable. It
is ideal for large size fiber such as 100/140 μm. The high
launched optical power level is useful for systems where
star couplers, taps, or inline connectors create large fixed
losses.
Consistent coupling efficiency is assured by the double-
lens optical system (Figure 1). Power coupled into any of
the three fiber types varies less than 5 dB from part to
part at a given drive current and temperature. Consistent
coupling efficiency reduces receiver dynamic range re-
quirements which allows for longer link lengths.
