PD-LD Inc. offers laser based fiber optic transceiver modules in convenient industry standard 1X9 style packages that are optimized for operation with both MM and SM optical fiber. The PTRX series modules are designed to operate at 155MBs over both 9/125um singlemode and 50/125um multimode optical fiber.
The transmitter section is built using 1310nm FP laser diodes and an IC driver that converts PECL signals into an optical output stream. The driver circuit maintains operation of the laser diode over an industrial operating temperature range of –40 to 85°C. The output of the laser diode is regulated such that they meet the Class 1 Eye Safety standards as outlined by the ITU documents EN 60825-1.
