RS 530 to Fiber Converter | RS-530 Fiber Optic MicroModem

Extend RS-530 Communications Over Fiber

The M62xxD Series provides a transparent fiber optic connection for RS-530 equipment requiring reliable communications over extended distances. Data, clock, and control signals are multiplexed for transmission across the fiber link and de-multiplexed at the remote MicroModem.

By replacing a copper connection with fiber optic transmission, the M62xxD provides a practical way to connect RS-530 equipment across remote locations while providing electrical isolation between connected equipment.

Transparent RS-530 Data, Clock and Control Transmission

The M62xxD supports synchronous and asynchronous communication with continuously variable data rates from 1 bps to 5 Mbps for terminal timing and 1 bps to 1 Mbps for source timing. The MicroModem operates in either full-duplex or simplex mode.

Its transparent operation maintains the independent data, clock, and control lines associated with the RS-530 interface. Handshaking is standard on all MicroModem models.

DCE and DTE RS-530 MicroModem Configurations

The M62xxD Series is available in both DCE and DTE configurations to accommodate different equipment interfaces.

• M6213D — DCE, multimode, up to 2 km
• M6223D — DTE, multimode, up to 2 km
• M6215D — DCE, singlemode, up to 20 km
• M6225D — DTE, singlemode, up to 20 km

DCE models use a female DB25 connector, while DTE models use a male DB25 connector. All models use an LC connector for the fiber interface.

Multimode and Singlemode Fiber Options

VERSITRON offers M62xxD MicroModems for both multimode and singlemode fiber installations.

Multimode models provide up to 2 km of transmission distance using 1310 nm fiber optics, while singlemode models provide up to 20 km. The product table in the datasheet specifies an 11 ± 1 dB link budget for the multimode models and 19 ± 1 dB for the singlemode models.

RS-530 Interface and Standards Support

The M62xxD is designed specifically for RS-530 communications and also supports RS-422 and MIL-STD-188-114A (Balanced). The datasheet also identifies support for RS-449 and V.35 with specific adapters, providing additional interface flexibility for compatible equipment.

VERSITRON offers RS-449 and V.35 adapters for the M62xxD Series, including DCE and DTE configurations.

Electrical Isolation for RS-530 Fiber Communications

The M62xxD uses fiber optic transmission to provide electrical isolation between connected equipment. The MicroModem's electrical isolation helps eliminate ground potential rise and provides dielectric isolation, making fiber an effective option for electrically separated RS-530 equipment.

Compact RS-530 Fiber Optic MicroModem

The M62xxD features a compact enclosure measuring approximately 1.0 x 2.4 x 4.5 inches and weighing approximately 0.425 lb. It can be installed directly with data terminal or communications equipment where space is limited.

For larger installations, the MicroModem can also be mounted in a 19-inch rack chassis, with redundant power applications supported by the MicroModem system.
