Description
The 40G QSFP Transceiver Module is engineered for high-performance optical communication, offering reliable data transmission over distances up to 80km. Compliant with the IEEE 40GBASE-ZR4 standard, this module supports advanced optical networking with a duplex LC connector for optical interfaces and a 38-pin electrical connector. Built to withstand extreme operating conditions such as temperature, humidity, and EMI interference, this transceiver ensures durability and long-term reliability in challenging environments.
Perfect for long-distance 40G Ethernet applications, the QSFP-40G-ZR4 module provides high bandwidth of up to 40Gbps and is compatible with leading industry devices, including Cisco and Huawei equipment. Its cost-effective nature, along with its exceptional compatibility, makes it an excellent choice for large-scale network upgrades or enterprise infrastructure projects. It operates with a single +3.3V power supply and offers flexibility through features like low-power mode, interrupt, and module present signals.
40G QSFP Transceiver Features:
80km Transmission Range: Ensures reliable long-distance optical communication with a reach of up to 80km.
IEEE 40GBASE-ZR4 Compliance: Meets industry standards for 40G Ethernet, guaranteeing compatibility with most modern network setups.
High Bandwidth: Offers up to 40Gbps aggregate bandwidth, with individual channels operating at 11.2Gbps each for efficient data transfer.
Dual LC Connector: Facilitates simple and secure optical connections with a duplex LC connector for the optical interface.
Cisco & Huawei SFP compatiblity:
Fully compatible with 40G QSFP devices from top brands like Cisco and Huawei, ensuring flexibility in your network equipment.
Digital Diagnostic Interface: Features a 2-wire serial interface for advanced diagnostics and control signals.
Advanced MUX/DEMUX Design: Supports 4-lane MUX/DEMUX for enhanced data throughput and network reliability.
Robust Design for Harsh Environments:
Built to endure extreme temperature ranges (0°C to 70°C) and resistant to humidity and EMI interference.
Power-Efficient: Operates on a single +3.3V power supply, ensuring lower energy consumption while delivering high performance.
RoHS Compliant: Adheres to global environmental standards, ensuring minimal impact on the environment.

The module converts 4 inputs channels of 10Gb/s electrical data to 4 CWDM optical signals. Multiplexes them into a single channel for 40Gb/s optical transmission.
Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.
The central wavelengths of the 4 LANWDM channels are 1296 nm, 1300 nm, 1305 nm and 1309 nm as members of the LAN WDM wavelength grid defined in ITU-T G694.2.
