Module/Transmitter

The NTT-13-xx Transmitters are fully compliant with SONET/SDH standards, OC-3/STM-1 for both Long Reach and Intermediate Reach. All modules satisfy Class I Laser Safety requirements in accordance with the US FDA/CDRH and international IEC-825 standards.

The functions of Transmitter are contained in a 20 pin-DIP package. The Transmitter incorporates a highly reliable 1300nm InGaAsP Laser and a driver circuit which converts PECL (Pseudo Emitter Coupled Logic) data to light. Also, the transmitter features an Automatic Power Control (APC) circuit to maintain the optical output power at a constant level against variations in ambient temperature and device aging. The laser bias current and back-facet light output can also be monitored.
The transmitter operates from a single +5V power supply over an operating temperature range of 0°Cto 70°C("A" option) or -40°C to +85°C("B" option). The fiber pigtail is terminated with SC, FC or SC connector.
