ETC FRM5N141GW

InGaAs-APD/Preamp
Receiver
FRM5N141GW
FEATURES
• Small Form Factor Package(GW): 9 pins coplanar
• Integrated Design Optimizes Performance at
Bit Rates up to 12.5Gb/s
• High Sensitivity: -27dBm (typ.)
• High Electrical Differential Output
• Overload Power: -7dBm (min.)
• Low Optical Return Loss (ORL): 27dB (min.)
• Wide Bandwidth: 10.5GHz (typ.)
• DC Coupled HBT IC Preamp
• Operates in both C and L wavelength bands
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 12.5Gb/s. The typical transimpedance (Zt) value of 1,300Ω optimizes
the total bandwidth for 10Gb/s application. The detector preamplifier is DC coupled
and has a high electrical differential output.
DESCRIPTION
The FRM5N141GW 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.
