Eoptolink EOLD-134HG-02-M56 400G QSFP-DD Optical Transceiver Module

Eoptolink EOLD-134HG-02-M56 is a high-speed 400G QSFP-DD optical transceiver module optimized for 4x100G DR4+ applications. Like other variants in the EOLD-134HG-02-MXX series, it is designed for data center and enterprise networking, providing a transmission reach of up to 2 km over single-mode fiber (SMF).

Core Technical Specifications
------------------------------------------
The M56 variant aligns with the primary specifications of Eoptolink's 400G 2km DR4+ portfolio:

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

* Wavelength: 1310 nm.

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

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

* Optical Connector: MPO-12 connector.

* Power Consumption: Typical power dissipation is less than 8W (Max < 10W).

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

Interface and Functional Design
------------------------------------------
* Electrical Interface: Features 8 channels of 53.125 Gbps (PAM4) electrical input/output, compliant with the 400GAUI-8 standard.

* Optical Interface: Features 4 independent channels of 106.25 Gbps (PAM4) optical signals.

* Integrated Gearbox: Utilizes a DSP with an integrated Gearbox to convert 8 electrical lanes into 4 optical lanes.

* Compliance: Fully compliant with QSFP-DD MSA, IEEE 802.3bs, and follows the FR specification of the 100G Lambda MSA.

* Break-out Support: Supports break-out applications, allowing for 4x100G configurations (e.g., connecting a 400G port to four independent 100G interfaces).

Diagnostic and Safety Features
------------------------------------------
* Monitoring: Includes an I2C interface with integrated Digital Diagnostic Monitoring (DDM/DOM), specified by CMIS (Common Management Interface Specification).

* Certifications: Safety certified by TUV, UL, and the FDA, and fully RoHS compliant.
