To meet domestic customers' demand for fully localized high-speed photodetector (PD) products, Fiberwdm has developed two high-speed PD products with bandwidths exceeding 18GHz and 40GHz after nearly 2 years of R&D and optimization. The 18GHz PD has a rise time of less than 20ps, and the 40GHz PD has a rise time of less than 8.5ps. Their responsivity is no lower than that of similar imported products from Finisar, Thorlabs, etc., and the tail oscillation is also well controlled. This series of high-speed detectors does not include a Transimpedance Amplifier (TIA) and features extremely low noise. It can be used for testing high-speed communication systems and femtosecond laser systems, and is a cost-effective fully localized product. The linear power supply independently developed by Fiberwdm can fully meet the requirements of high-speed detectors in scientific research applications.

Detectors of this series are directly interchangeable with Thorlabs' battery-equipped products and perform no worse than Thorlabs' similar products in all aspects. In addition to detectors with existing specifications, customization services are also available. Various parameters of the detector (such as supply voltage, bandwidth, etc.) can be adjusted according to customer requirements to meet specific application needs. This series is specifically designed for laser measurement systems. It has no gain amplification, comes with a built-in battery, and serves as a cost-effective detector product for high-power laser laboratories.

The M1x16 optical switch is connected to the optical path by connecting or blocking the optical signal. the switch has non-mechanical configurations and activated via an electrical control signal. the switch also has build-in circulator and isolator functions. Products are widely used in aerospace and military equipment.

As 5G, IoT, and cloud computing develop rapidly, bandwidth demand grows. PON technologies (GPON, XGS-PON, NG-PON2+PtP) are evolving, with OTDR for network fault diagnosis and maintenance. 4CH WDM enables their coexistence on the same fiber, boosting network bandwidth and flexibility.

In the digital transformation era, demand for high-speed, reliable, flexible communication networks is unprecedented. Passive Optical Networks (PON) are a cornerstone of modern communication infrastructure, supporting apps from home broadband to enterprise networks and more. To meet growing bandwidth needs and ensure future-proof networks, integrating 5CH WDM (Five-Channel Wavelength Division Multiplexing) with GPON, XGS-PON, NG-PON2, RF Video, and OTDR offers a comprehensive solution that maximizes fiber use and enhances service delivery.

100G QSFP28 Digital Coherent Optics (DCO) transceiver support 100G transmission over standard single-mode fiber (SMF) up to 80 km, with coherent detection of QAM modulated signals. The electrical interface specifically supports 100GE with SM - 100G - FEC application. On the optical side the optical specifications are aligned with IEEE standard 802.3bm 100GBASE-ZR(28) and ITU-T G.698.2 OWDM-IBA2(CF)/DW100-IBA2(CF) , which define a 2 95GBd dual-polarization differential QPSK modulation format.   The module is offered in both commercial temperature (0°C to 70°C) and industrial temperature (-40°C to 85°C) versions, with optional configuration to support flexible oscillator laser wavelength tunable and the transceiver power dissipation of less than 6.0W. The local "automatic" is full C-band.   The transceiver module is compliant to the Specification for QSFP+ 28 Gb/s 4X Pluggable Transceiver Solution (QSFP28)  and specifications referenced therein . The transceiver is RoHS compliant and lead-free per Directive 2011/65/EU.

This product is a high-performance 10G photoelectric converter, which uses optical-electric conversion to achieve balanced amplification of optical signals, clock extraction and optical regeneration, and adopts WDM (DWDM / CWDM) technology, which can realize one or more channels on a single fiber Long-distance transmission of optical signals. The 10G mini Ethernet optical-to-electrical converter is designed by our company for big data and high-speed digital broadband networks. It is mainly used for metropolitan optical fiber digital broadband network upgrade and expansion, and large-capacity server data transmission. The product provides high-quality, high-reliability, high-bandwidth, and low-price design ideas to provide users with sufficient bandwidth, stable performance, and powerful network solutions.

Amid the era of digital transformation, the demand for high-speed, reliable, and flexible communication networks has reached an unprecedented level. Passive Optical Networks (PON) have established themselves as a cornerstone of contemporary communication infrastructure, underpinning a diverse array of applications—ranging from residential home broadband to enterprise-grade networks, and extending even further into broader use cases. To address the ever-increasing bandwidth requirements and secure future-proof network rollouts, the integration of 4CH WDM (Four-Channel Wavelength Division Multiplexing) with key technologies including GPON, XGS-PON, NG-PON2, and RF Video delivers a comprehensive solution. This integration not only maximizes fiber optic utilization but also significantly boosts the capabilities of service delivery.

As emerging technologies like 5G, the Internet of Things (IoT), and cloud computing develop at a fast pace, there is a steady rise in bandwidth demand. To keep up with this demand, Passive Optical Network (PON) technologies are advancing as well. Currently, the primary PON technologies in use include GPON, XGS-PON, and NG-PON2; meanwhile, OTDR (Optical Time Domain Reflectometer) serves as a tool for diagnosing network faults and carrying out maintenance work. By leveraging 4CH WDM (Four-Channel Wavelength Division Multiplexing) technology, these various technologies can coexist on a single fiber—this not only boosts the network’s bandwidth but also improves its flexibility.
