PD-LD has developed a novel pressure-resistant 1×9 transceiver, which can withstand extreme pressures up to 800 psi and is well suited to marine, aerospace, and defense applications. These pressure-tolerant fiber optic transceiver modules are in convenient industry standard 1×9 style packages. The PTR622-PT series modules are designed to operate at 622 Mbps data rate over 9/125um single mode optical fiber.
A 1310 nm (-B35)/1550nm (-B53-S) FP and an InGaAs PIN photodiode are integrated with a WDM filter to form a bi-directional single fiber optical subassembly (OSA). A LD driver IC that converts differential input LVPECL logic signals into an analog laser driving current drives the laser. The photodiode is connected to a circuit providing post-amplification, quantization, and optical signal detection.
