Description

The Model 2245 is a multi-featured fiber optic modem that transmits standard DSX-3 (44.736 Mbps) signals over singlemode or multimode fiber optic cable.

The Canoga Perkins 2245 transports any B3ZS coded data stream with either framed or unframed formats. It provides complete diagnostic and fault isolation features when transporting M13 or C-bit parity framed DSX-3 signals. The Canoga Perkins 2245 is ideal for a variety of high speed applications including extending the DS3 point of presence from the Telco demarcation point, linking T3 multiplexers over fiber optic cable in a campus network, providing a secure fiber optic link for high speed cryptographic devices or as an ATM feeder link.

The DS3 electrical interface provides a standard DSX-3 signal and conforms to applicable ANSI, Bellcore and AT&T standards. The optical interface may be configured with either LED, ELED or Laser transmitters and with ST-style or FC/ PC connectors.

The Canoga Perkins 2245 operates at 850nm or 1310nm and is compatible with all popular sizes of single mode and multimode fiber optic cable. Loss budgets are 10dB for multimode up to 20dB when using singlemode fiber.
For applications that require multiple modems, the 2201 Rack Assembly holds up to ten 2200 Series Modems. Standard features of the 2201 include audio, visual and dry contact alarms in the event of power supply failure. Redundant power is also available as an optional feature.
