Description(XMT5170B-155-SC datasheet and pdf download)
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 +5V 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.
