What data rate and modulation does the EOLD-134HG-02-M46D support?

Supports 425Gbps total using 4x106.25Gbps PAM4 optical signals at 1310nm, with 8x53.125Gbps PAM4 electrical interface per IEEE 802.3bs 400GAUI-8. Enables 400G Ethernet FR4 and InfiniBand EDR with breakout to 4x100G QSFP28 FR modules.

What is the maximum transmission distance and fiber type?

Reaches 2km over G.652 single-mode fiber using MPO-12 connector. Transmitter power -2.4 to +4.0 dBm/lane with PIN/TIA receiver, optimized for intra-DC spine/leaf and edge aggregation links.

Is this transceiver compatible with Dell Networking switches?

Yes, listed as alternate part to Dell Q56DD-400G-EDR4/0599TF. Compatible with PowerSwitch Z9332F-ON, Z9432F-ON, Z9664F-ON platforms with Dell transceiver encoding for full recognition and management.

What management and diagnostic features are included?

CMIS 4.0 compliant with DDMI over I2C interface providing real-time monitoring of temperature, voltage, laser bias, Tx/Rx optical power. Supports hot-swap insertion without traffic disruption in live networks.

What power requirements does the module have?

Single 3.3V supply with maximum dissipation under 10W. Low power design suitable for high-density 400G fabrics without exceeding typical switch port power budgets.

Can it break out to lower speed ports?

Yes, supports 1x400G native and 4x100G breakout mode over SMF to QSFP28 FR transceivers, leveraging internal gearbox for mixed-speed data center transitions.

Product overview

The Eoptolink EOLD-134HG-02-M46D is a high-performance QSFP-DD optical transceiver module designed for 400 Gigabit Ethernet applications in data center environments. Supporting 425Gbps aggregate data rate via 4x106.25Gbps (PAM4) per lambda over single-mode fiber up to 2km, it converts 8 channels of 53.125Gbps PAM4 electrical signals to 4 parallel 100Gbps PAM4 optical channels at 1310nm central wavelength. Compliant with QSFP-DD MSA, IEEE 802.3bs 400GAUI-8 electrical interface, and CMIS 4.0, it features MPO-12 connector, integrated digital diagnostics via I2C, and PIN/TIA receiver array. Power consumption is under 10W from single 3.3V supply, operating across 0°C to 70°C commercial temperature range. RoHS compliant with safety certifications (TUV/UL/FDA). Listed as Dell-compatible (alternate to Q56DD-400G-EDR4/0599TF), it integrates with Dell PowerSwitch platforms like Z9332F-ON, Z9432F-ON for hyperscale interconnects. Ideal for 400G-FR links, InfiniBand, and breakout to 4x100G, enabling high-density spine/leaf architectures with low latency and high reliability for cloud and AI workloads.
