PD-LD Inc. offers multimode laser based fiber optic transceiver modules in convenient industry standard 1×9 style packages. The PTR155 series modules are designed to comply with SONET/SDH 155 Mbps operation over 62.5/125um multimode optical fiber. A 1310 nm (-B35) or 1550nm (-B53) FP laser 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.

  • RoHS compliant
  • Compatible with 155 Mbps ATM and SONET OC-3 SDH STM-1
  • Industry standard 1×9 footprint
  • SC Connector
  • Single power supply 3.3 V
  • Differential PECL inputs and outputs
  • Compatible with solder and aqueous wash processes
  • Class 1 laser product complies with EN 60825-1

Signal Detect indicates the receiving of a good optical signal. This is a single-ended LVPECL output. When the input optical power decreases, Signal Detect will change from high state to low state at a level  (de-assert point) below the sensitivity. As the input optical power increases, Signal Detect will change back from low state to high state at assert point. The assert level is at least 1.0 dBm higher than the de-assert level.
