XMT5370-155

Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided each limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time.

The XMT5370-155 is a high performance uncooled optical laser transmitter for CCITT SDH and ANSI SONET applications. It is designed with an ECL/PECL logic interface for 155 MBd transmission.

The transmitter incorporates several features which simplify system design. It may be operated with either +5 V or 5 V power supplies. Standard 10 KH ECL data interface enables direct interface with PECL or ECL logic.

The compact transmitter module of the XMT5370-155 contains a pigtailed laser, data interface, bias and modulation control circuitry. Thus, no external components or adjustments are necessary. Finally, a laser disable input is provided to shut down the laser for standby or test purposes.

The XMT5370-155 has -11 dBm mean output power for short and intermediate reach systems. The XMT5370-155 includes analog outputs which are proportional to laser current and optical power. These may be used with external circuitry to detect end-of-life, or over temperature conditions.

The transmitter is packaged in a 20 pin 0.4" pitch DIP. An evaluation board is available for this product. Contact your local representative for more details.
