XMT5170-155

155 Mb/s Logic Interface Laser Transmitter for OC3/STM1 Preliminary Technical Data XMT5170-155 Features SONET/SDH Compliant to STM1 L-1.1 OC3 LR-1 –40°C to +85°C Operation Compact 20 Pin Package ECL/PECL Logic Interface Multisourced Pinout Fully Interchangeable High and Low Power Versions Description The XMT5170-155 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 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 XMT5170-155 has -2 dBm mean output power for long haul systems. The XMT5170-155 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.
