ZTE100G Single-Mode Optical Module

The ZTE100G Single-Mode Optical Module is a QSFP28 100Gbps transceiver designed for long-distance single-mode fiber applications, supporting high-speed, reliable, and energy-efficient connectivity.OverviewThe ZTE100G module, such as the ZTE 033030600033, is a QSFP28 full-duplex optical transceiver that aggregates four independent 25Gbps channels to achieve a total data rate of 100Gbps over single-mode fiber (SMF) for distances up to 2 km . It is designed for data center interconnects, metro networks, and campus backbones, where long-distance, high-speed connectivity is critical . The module supports MTP/MPO fiber ribbon connectors for optical alignment and uses a 38-pin MSA-compliant edge connector for electrical interfacing .Key FeaturesForm Factor: QSFP28, enabling high port density and compact deployment .Transmission Technology: 4x25Gbps channels combined into 100Gbps, with options for single-lambda PAM4 modulation in advanced variants .Supported Distances: Typically 2 km for standard ZTE QSFP28 modules; single-lambda variants can extend from 500 m (DR) up to 40 km (ER BIDI) or more depending on the type .Wavelength: Standard 1310 nm for single-mode operation; some single-lambda modules use DSP-based conversion for 100G PAM4 signals .Power Consumption: Around 3.3V supply, with typical power usage of 4–4.5W depending on the module type .Digital Diagnostics: I2C interface provides real-time monitoring of temperature, voltage, optical power, and other operational parameters .Environmental Tolerance: Designed to operate under harsh conditions including temperature, humidity, and EMI interference .ApplicationsData Center Interconnect (DCI): Seamless high-speed connections between campuses or metro sites .Cloud and HPC Deployments: Reliable 100Gbps throughput with low latency for demanding workloads .Metro and Core Networks: Single-mode optics minimize modal dispersion, ensuring low bit error rates (BER) over long distances .Future-Proof Infrastructure: Supports potential upgrades to 200G, 400G, or 800G speeds without re-cabling .Single-Lambda VariantsFor cost efficiency and higher density, 100G single-lambda optical modules convert four 25G NRZ signals into a single 100G PAM4 optical signal using a DSP, reducing component count and power consumption . Examples include:100GBASE-DR: Up to 500 m over SMF, ideal for leaf-spine data center connectivity .100GBASE-FR: Short-reach single-mode, 1310 nm, 4x25G NRZ channels, max 4W power .100GBASE-LR: Up to 10 km, suitable for inter-building or core network links .100GBASE-ER/ERL: Long-distance, 30–25 km, with duplex LC connectors .SummaryThe ZTE100G Single-Mode Optical Module is a high-performance, energy-efficient, and future-proof solution for modern networking environments. Its QSFP28 form factor, single-mode fiber support, and optional single-lambda PAM4 technology make it ideal for data centers, metro networks, and long-distance interconnects, providing reliable 100Gbps connectivity with low latency and excellent signal integrity .
