This is a family of precision-machined optomechanical mounting blocks used to fix and align miniature fiber optic components such as collimators, fiber arrays and ferrules. The blocks are made of aluminum alloy with a black anodized finish to suppress stray-light reflection and improve wear resistance. The series includes several configurations: blocks with circular counterbored holes and top set screws for locking cylindrical collimator tubes, blocks with rectangular slots, and blocks fitted with square metal sleeves (stainless steel / nickel-plated) for receiving MT-type ferrules or fiber array endcaps. The flat square base provides a stable reference surface for adhesive bonding or screw mounting onto optical sub-assemblies, making these blocks ideal for compact photonic module packaging.

Santec's Unidirectional Tap-Integrated Photo Detector (IPD-UD) is an optical power monitoring device consisting of individual tap-integrated photo detectors. The IPD is very compact and can be easily mounted on a PCB for system use. It delivers excellent optical properties, including a broad wavelength range covering the C- and L-band, low insertion loss, and high sensitivity. By integrating the tap and the photodetector into a single device, the IPD eliminates the need for a separate optical fiber coupler/splitter and photodetector, providing a simple, low-cost solution for optical power monitoring in DWDM and switching systems. Santec's Unidirectional Tap-Integrated Photo Detector is especially useful for amplifier systems.

Return Loss: Min. 45dB PD Sensitivity: Min. 800mA/W (All operating conditions, 5V bias) Dark Current: Max. 5nA (70°C, 5V bias)

The Santec PDA is an optical power monitoring device consisting of terminating photodetectors integrated with fiber inputs. It is very compact and easily mounted on a PCB for system use, providing a simple and low-cost solution for power monitoring in DWDM and amplifier systems. Qualified to GR-468-CORE for high reliability, the PDA series is available in 1, 4, 8, and 10-channel versions with flexible connector options (FC, SC, MU, LC in SPC or APC polish) and pin assignments (2-pin PD, anode common, cathode common, or separate pins), covering the 1510~1610nm wavelength range for telecom and optical communication applications.

Footprint Reduction vs Standard IPD (%): 60 Volume vs Standard IPD (%): 75 Minimum Fiber Bending Radius (mm): 5

The MTP devices are miniaturized tap-integrated photodetectors. They achieve a 60% reduction in footprint and 75% of the volume compared with a standard IPD (Integrated Photo Detector), while maintaining high performance and high reliability. The MTP series is designed for high-density integration in next-generation optical network systems.
