FEATURES
DESCRIPTION
• HIGH DATA RATE CAPABILITY:
2.5 Gbps
NEC's NR4500BP-CC and NR4500CP-CC are 2.5-Gbp/s
APD receivers in a coaxial module with an internal preamplifier.
These modules are ideal as receivers for Synchronous Digital
Hierarchy (SDH) system, STM-16, ITU-T recommendations.
• RECEIVER SENSITIVITY:
PLOW = -32 dBm
• APD WITH HIGH PERFORMANCE GaAs
PRE-AMPLIFIER
• OPERATING CASE TEMPERATURE RANGE:
TC = 0 to +85°C
• COAXIAL MODULE WITH SC-UPC CONNECTOR
• SINGLE-END OUTPUT
