Fibre Optic Receiver
The PTAV series are optical receivers suitable for bit rates
from 155 to 622 Mbit/s long and intermediate reach
SDH/SONET/ATM single mode applications. They use
Bookham Technology one piece fibre alignment technology
offering high stability and reliability and are capable
of satisfying the requirements of the Bellcore quality
specification TA-NWT-00983. Bookham's unsurpassed
quality and reliability are featured in a rugged,
hermetically sealed, ceramic package fully tested for
environmental integrity.
The receivers are designed to be physically small and their 8 pin
mini DIL packages are near pin-compatible with industry
standard 14 pin DIL devices. The optical element is an InGaAs
PIN photodiode coupled to a multimode fibre pigtail, and an
integral transimpedance amplifier with AGC is featured. Operation
from either dual +5 / -5.2 V supplies or single +5 V supply is
specified by selecting a PTAV**L or PTAV**C respectively. The
PTAV series is compatible with the LCV mini
DIL transmitter.
