• Electrical Differential Output
• Wide Bandwidth: 8.5GHz (typ.)
• Operates in both C and L wavelength bands
• Wide Operating Temperature Range: -5°C to +75°C
FRM5N142GW
APPLICATIONS
This APD with HBT preamplifier is intended to function as an optical receiver
at 1,310nm or 1,530-1,610nm in SONET, SDH, DWDM or other optical fiber
systems operating up to 10.7Gb/s. The typical transimpedance (Zt) value
of 4,000optimizes the total bandwidth for 10Gb/s application. The detector
preamplifier is DC coupled and has an electrical differential output.
DESCRIPTION
The FRM5N142GW incorporates a high bandwidth InGaAs APD photo diode, a GaAs
HBT IC amplifier in a hermetically sealed Small Form Factor package (SFF). The APD is
processed with modern MOVPE techniques resulting in a reliable performance over a wide
range of operating conditions. The lens coupling system and the single mode fiber are
assembled using Nd YAG welding.
