OPT-700 - Serial to Fiber Optics Converter Module
(Supports Hot Swap)
Part Number
OPT-700 (EIA-232/EIA-485 to Fiber Optics Converter)
Description
The OPT-700 is a Fiber Optic Modem designed to provide a versatile connection between
asynchronous serial communication interfaces such as EIA-232-C and EIA-485 using Fiber Optic
cable. It will allow any piece of equipment that uses half-duplex asynchronous serial communication
at distances up to 4.0 km with great benefit of EMI immunity.
It can be configured point-to-point or in a multi-drop configuration using the Repeat feature.
The OPT-700 supports a broad range of configurable baud rates for the asynchronous serial
communication. EIA-232-C can work between 2400 and 115.2Kbps, while EIA-485 works from 2400
till 920Kbps.
Once Fiber Optic is immune to EMI/RFI and ground loops, the Modem can replace converters and
isolators when connecting remote devices.

Main Characteristics
9 Works directly in the LC700/DFI back-plane draining power from the Inter-Module-Bus
(IMB).
9 Can be used in a stand-alone mode with an external power supply.
9 Accepts EIA-232-C or EIA-485 with configurable baud rates.
9 Point-to-Point or Multi-drop Fiber Optic communication.
9 Great solution to increase link distances and eliminate EMI or Grounding problems.
Fiber Optic Cable
This is a Dual or Simple multi-mode, 62.5 or 50/125µm fiber optic cable with ST connectors and
a Maximum length of 4000m (12,000ft).
