Emitter products include a wide range of lasers (FP, DFB, pulsed) in wavelengths ranging from 630 to 1650nm. Light-emitting diodes (SLEDs, ELEDs, etc.) and VCSELs are also available. PD-LD excels in focusing light into virtually all common fibers and connectors.
PD-LD offers Fabry-Perot (FP) and distributed feedback (DFB) lasers in wavelengths ranging from 630-1650nm. Isolated and non-isolated versions are available, as are customized options.
Single-mode and multi-mode surface-emitting LEDs are available at 850 and 1310nm wavelengths. Standard Edge Emitting LEDs, ELEDS are available at 1300 and 1550nm.
Pulsed laser diodes in wavelengths ranging from 1310 to 1650nm are available in a variety of packaging options.
Choose from several different varieties of fiber coupled 850nm Vertical Cavity Surface Emitting Lasers or VCSELs. These devices may be mounted in connector receptacle style packages or fiber pigtailed to facilitate optical coupling into Multimode optical fiber.
Multiple device assemblies include bi-directional laser modules, as well as laser combiners and triplexers, which combine 2 or 3 wavelengths respectively. PD-LD includes several discontinued device configurations from other manufacturers. Call us for details if your device is not found here.
Laser combiners combine 2 emitters, say, 2 lasers (e.g., 1310 nm and 1550 nm devices), or 2 LEDs, so that both are coupled to one fiber (SM or MM).
PD-LD Triplexers allow the designer to create test instrumentation with a single optical port rather than three. From this single port the user can switch between 1310nm and 1550nm laser sources for transmitting, or switch to functioning as a receiver .
Germanium PIN & APDs available in standard and custom sizes and packages cover the spectral range of 850 – 1600nm.
A wide variety of InGaAs PIN Photodiodes & APDs are available in digital, analog, and large-area options. Spectral ranges available: InGaAs PIN: 800 – 1700nm and 1000 – 2600nm – InGaAs APD: 1000 – 1600nm
PD-LD’s Silicon Photodiodes & Avalanche Photodiodes (APDs) are available with active areas ranging from 230µm to 3.0mm covering the spectral range of 400 – 1100nm.
PD-LD’s transceivers provide transmission and receiving capabilities in one compact device. Standard SFP (small-form pluggable) and 1×9 styles are available at speeds ranging from 155MB/s to 2.5 GB/s. Custom-made ruggedized transceivers, for use in high-pressure or harsh environments, are also available.
PD-LD Inc. offers laser diode based fiber optic transceiver modules in convenient industry standard 1×9 style packages. The PTRxxx series modules are designed to operate at 155 Mbps, 622Mbps, or 1.25 Gbps data rate over either multimode or 9/125um single mode optical fiber.
PD-LD has developed a new line of ruggedized transceivers that maintain performance in high-pressure environments without the need for a sealed and pressurized cover. These transceivers are available in a 1×9 and SFP footprint
Laser diode based fiber optic transceiver modules in industry standard Small-Form-factor-Pluggable (SFP) packages are designed for 155 Mbps, 1.25Gbps and 2.5Gbps data rate applications, including SONET OC-3, SDH STM-1, Fiber Channel, Fast and Gigabit Ethernet over either multimode or 9/125um single mode optical fiber.
Integrated photodiode/transimpedance amplifier assemblies provide high signal:noise performance and preserve circuit board space.
These 1310nm Edge Emitting Type devices have been optimized for coupling into 9/125 micron optical fiber for use in singlemode fiber optic applications. FC, ST and SC receptacles are also available.
Low-noise, high-responsivity InGaAs photo detectors paired with a transimpedance amplifier (TIA) in convenient fiber coupled packages have been optimized for speeds of 155, 622, 1250, and 2500Mb/s.
