Eoptolink EOLD-134HG-02-M59 400G QSFP-DD Optical Transceiver Module

Eoptolink EOLD-134HG-02-M59 is a high-speed 400G QSFP-DD optical transceiver module specifically designed for 4x100G DR4+ applications. It is engineered for high-density 400 Gigabit Ethernet links over distances of up to 2 km using single-mode fiber (SMF).

Core Technical Specifications
------------------------------------------
The module operates by converting 8 channels of 53.125Gbps (PAM4) electrical signals into 4 channels of 106.25Gbps (PAM4) parallel optical signals.

* Data Rate: Supports aggregate data rates up to 425 Gbps.

* Wavelength: 1310 nm center wavelength across 4 parallel lanes

* Transmission Distance: 2 km over standard G.652 single-mode fiber (SMF)

* Form Factor: QSFP-DD (QSFP56-DD) MSA compliant

* Optical Connector: MPO-12 (MTP/MPO-12) optical receptacle

* Electrical Interface: 8 channels of 53.125 Gbps PAM4 (400GAUI-8)

* Optical Interface: 4 channels of 106.25 Gbps PAM4

* Power Consumption: Typical dissipation < 8W (Max < 10W to 12W depending on conditions)

* Operating Temperature: 0°C to 70°C (Commercial case temperature range).

Features and Compliance
------------------------------------------
* Modulation Format: Uses PAM4 (4-level Pulse Amplitude Modulation) for both electrical and optical signals to achieve high data density.

* Standards Compliance: Compliant with QSFP-DD MSA and IEEE 802.3bs 400GAUI-8 interface standards.

* Monitoring: Includes an I2C interface with integrated Digital Diagnostic Monitoring (DDM) for real-time tracking of parameters like power and temperature.

* Break-out Capability: Supports "break-out" applications, allowing a 400G port to be split into 4 independent 100G single lambda data lanes.
