    GIGALIGHT Unveils COLOR ZR+ Quad-Carrier (4x25G NRZ) 100G QSFP28 DWDM4 Modules with O-BAND/C-BAND Options

    Shenzhen, China, November 27, 2023 – Long-distance data transmission operates through two distinct modes: coherent and non-coherent. Today, GIGALIGHT officially unveils two trailblazing 100G QSFP28 PSM DWDM4 non-coherent long-distance optical modules. These modules, built upon a 4x25G NRZ quad-carrier DWDM solution, offer options in both the C-band and O-band spectra, effectively spanning distances exceeding 80km. They aim to provide more cost-effective DWDM transmission solutions for Data Center Interconnects (DCIs) and metropolitan networks. Compared to traditional coherent solutions, this approach offers advantages such as lower pricing, lower power consumption, lower latency and easier deployment.

    Color ZR+ C-BAND 100G QSFP28 PSM DWDM4

    The GIGALIGHT Quad-Carrier Color-ZR+ C-BAND 100G QSFP28 PSM DWDM4 optical module features an MPO-12 interface on the optical side, designed with a 12-core MPO. When coupled with an external Wavelength Division Multiplexer/Demultiplexer, EDFA (Erbium-Doped Fiber Amplifier) and DCM (Dispersion Compensation Module), it achieves transmission distances of at least 80km. The product employs 4x 25G C-band 100GHz DWDM EML lasers on the transmission end and PIN detectors on the receiver end, providing 48 wavelengths. With a total power consumption of less than 5W, this module achieves a total bandwidth of 1200G under dual-fiber transmission conditions and 400G under single-fiber conditions. It seamlessly connects to 100G QSFP28 switch ports, eliminating the need for traditional DWDM optical layer equipment. Additionally, GIGALIGHT offers an all-in-one solution, including proprietary intelligent 1U optical layer equipment featuring DWDM EDFA, AAWG, and adjustable TDM or fixed DCM, providing customers with a comprehensive non-coherent DWDM transmission solution for rapid business deployment.

    Color ZR+ O-BAND 100G QSFP28 PSM DWDM4

    GIGALIGHT’s quad-carrier Color ZR+ O-BAND 100G QSFP28 PSM DWDM4 optical module features an MPO interface with a 12-core configuration. When combined with an external Wavelength Division Multiplexer/Demultiplexer and SOA amplification, it achieves a transmission distance of up to 80km. The module’s transmitter employs a 25G O-BAND 150GHz DWDM DML laser, while the receiver employs a PIN detector, offering 16CH wavelengths with a power consumption of less than 5W. In a dual-fiber configuration, the module delivers a total network bandwidth of 400G. It can be directly inserted into a 100G QSFP28 switch port, eliminating the need for traditional DWDM optical layer equipment and dispersion compensation modules. Additionally, GIGALIGHT provides an all-in-one solution with its self-developed intelligent 1U optical layer equipment, including SOA amplification and a 150GHz AAWG, offering customers a complete non-coherent DWDM transmission solution for swift business deployment.

    400G Transmission Solution with O-BAND 100G QSFP28 PSM DWDM4

    GIGALIGHT’s Industrial Grade Triple-Proof 100G QSFP28 Hardened Modules Verified by Authoritative Reliability Testing

    SHENZHEN, China Nov. 23, 2023 – GIGALIGHT’s pioneering triple-proof 100G QSFP28 SR4/PSM4/CWDM4 hardened modules have cleared rigorous tests by the Center for Testing International (CIT), perfect for tough conditions like high temperatures, humidity, and corrosion.

    As is known, various materials such as metals, resins, and even polymer materials are susceptible to environmental changes, leading to an overall degradation in product performance. The term ‘triple-proof treatment’ refers to surface treatments applied to products to resist moisture, salt-mist, and mold, reducing or eliminating the adverse effects of harsh environments on product performance and reliability.

    As a critical component used in optical transmission or switches, optical modules primarily consist of three major parts: PCBA, metal housing, and optical components/optical engines. They are more susceptible to environmental influences in applications compared to IT equipment. The hardened modules mainly undergo explosive diagram analysis and deep triple-proof treatment targeting the overall composition of the optical modules. The PCB gold fingers adopt a unique nickel-palladium-gold process, while the PCBA and optical component sections employ overall plating and coating reinforcement processes, creating a dual protection of plating and triple-proof materials. The internal space and housing of the modules are sealed with matching sealing rings, forming a triple protection to isolate external medium erosion.

    GIGALIGHT 1G/10G hardened optical modules have been manufactured and delivered in bulk quantities for low-speed product lines. The newly launched 100G QSFP28 SR4/PSM4/CWDM4 hardened optical modules are designed to support both industrial and commercial applications. They have undergone rigorous testing, including a 95% humidity reliability test, which they have successfully passed. Additionally, they have been assessed by a domestic authority,CTI, meeting several standards: the waterproof and dustproof property test meets the IEC 60529 standard IP67 level, the anti-mold property test meets the IEC 60068-2-10 standard, a duration of 28 days overall mold-free and salt-spray proof feature complying with GR 487 standards for neutral salt spray corrosion resistance.

    GIGALIGHT 100G QSFP28 industrial grade hardened optical modules series exhibit excellent triple-proof capabilities, effectively alleviate concerns regarding the application environment and corresponding maintenance of optical module products. Particularly suitable for harsh environments (high dust, high humidity, high corrosion, etc.) and harmful environmental applications, as well as edge server application requirements.
