Eoptolink EOLD-134HG-02-M5A 400G QSFP-DD Optical Transceiver Module

Eoptolink EOLD-134HG-02-M5A (part of the EOLD-134HG-02-MXX series) is a 400G QSFP-DD optical transceiver module designed for high-density, high-speed 400 Gigabit Ethernet links. It is primarily utilized in data centers and enterprise networking for long-distance connectivity.

Core Technical Specifications
------------------------------------------
According to Eoptolink's technical data, the module features the following key performance parameters:

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

* Wavelength: 1310 nm.

* Transmission Distance: Up to 2 km over Single-Mode Fiber (SMF).

* Form Factor: QSFP-DD (Quad Small Form-factor Pluggable Double Density).

* Optical Connector: MPO-12 connector.

* Power Dissipation: Typically < 8W to 10W (depending on operating conditions).

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

Interface and Architecture
------------------------------------------
* Electrical Interface: The module has 8 independent electrical channels at the host side, each with a data rate of 53.125 Gbps (PAM4), compliant with the 400GAUI-8 interface.

* Optical Interface: It uses 4 independent 100G single lambda data lanes. An integrated DSP/Gearbox converts the 8 electrical lanes into 4 optical channels of 106.25 Gbps each.

* Standards Compliance: The module is compliant with the QSFP-DD MSA (Multi-Source Agreement) and follows the FR specification of the 100G Lambda MSA.

Key Features
------------------------------------------
* Break-out Applications: Supports break-out configurations, allowing for independent channel functions such as 4x100GbE for aggregation or shuffle applications.

* Digital Monitoring: Includes an I2C interface with integrated Digital Diagnostic Monitoring (DDM).

* Safety and Reliability: Features safety certifications from TUV, UL, and FDA, and is fully RoHS compliant
