XMT5170B-622

• SONET/SDH Compliant to STM4 L-4.1 OC12 LR-1
• 0 to +70Operation
• Compact 20 Pin Package
• ECL/PECL Logic Interface
• Multisourced Pinout

The XMT5170B-622 is a high performance uncooled optical DFB laser transmitter for CCITT SDH and ANSI SONET applications. It is designed with an ECL/PECL logic interface for 622 Mb/s transmission.

The transmitter incorporates several features which simplify system design. The XMT5170B-622 may be operated with either +5 V or - 5 V power supplies. Its 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 XMT5170B-622 provides analog voltage outputs which are proportional to laser bias 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. Contact your local representative for more details.
