800 KBit/s DataLink Transmitter and Receiver Pair
工业级800kbps塑料光纤TTL光模块电力抄表等应用300米传输，采用LED可见绿光进行数据传输，应用于光纤传感，电力抄表、数据采集、工业控制等应用。
The transmitter is based on the highly reliable
gallium nitride LED technology.
based on a fully integrated differential photo-
TIA and limiting amplifier.
The transmitter can be driven from TTL type logic
drivers and the receiver is a single-ended TTL/CMOS
type output. Both transmitter and receiver operate
over the industrial temperature range of -40 ⁰C to
+85 ⁰C supporting many industrial applications where
reliable command and control response is required in
electrically harsh environments.
The transmitter utilizes a green, 522 nm, eye-safe
highly-efficient gallium nitride LED. It operates over a
wide range of drive current that can be adjusted
using serial resistors to minimize current
consumption for known fiber distances.
The receiver has dual photo-diodes which act as a
differential light sensor giving enhanced immunity to
EMI and EMC from the local environment making the
unit ideal for use in electrically noisy applications. The
receiver has a single data output compatible with
TTL/CMOS electronics. The transmitter and receiver
are typically used at 1 MBd over POF in industrial serial
bus protocol links. |
