Z-BLOCK Filter (Z-Type Integrated Filter) is an Optical Communication Filter developed by MULTI IR for high-integration optical modules. Its core advantage is to integrate multiple functions such as "combining, splitting, and wavelength filtering" into a single Z-type optical component, simplifying the internal design of the optical module. The product adopts high-precision Ion Beam Sputtering process to deposit multiple layers of dielectric thin films, integrating 3-5 channels of filtering functions. The total insertion loss is ≤ 0.8dB (single-channel insertion loss ≤ 0.2dB), the isolation is ≥ 38dB, and the volume is only 40%~50% of that of the traditional discrete filter combination. This product is compatible with high-integration optical modules (such as SFP+ and QSFP28), with a wavelength tolerance of ±0.15nm, meeting the precision requirements of high-speed modules; at the same time, it has excellent mechanical stability, and its anti-vibration (10-2000Hz) and anti-impact (1000G) performance meet industrial standards; combined with MULTI IR's customization service (MULTI IR Filter Customization), the integrated functions and packaging size can be adjusted according to the needs of the optical module, supporting lead-free and environmentally friendly materials, complying with RoHS standards, and providing a highly integrated and miniaturized optical solution for high-density optical communication equipment.

Application Field

This product is mainly applied to high-density optical modules in large data centers, compatible with 10G/25G high-speed interconnection of servers and switches, reducing module volume and power consumption; in the Active Antenna Unit (AAU) of 5G base stations, as a core integrated component of the optical module, it realizes efficient combining and splitting of signals; at the same time, it is suitable for high-integration WDM equipment in communication backbone networks, simplifying the internal optical path design of the equipment and improving the equipment port density; in addition, in the fields of aerospace and vehicle-mounted optical communication, it can meet the strict requirements of equipment for miniaturization and high reliability, and is a high-end core component in "high integration-miniaturization" optical communication scenarios.
