HG Genuine compatible MQD-56F2C-1 Description
MQD-56F2C-1 is HG Genuine's 400GBASE-FR4 QSFP-DD -- HG Genuine (also known as Genuine Optics or Genuine Optronics) is a Chinese optical module OEM supplying transceivers to data center operators and telecom companies at scale. "MQD" in their naming convention indicates the QSFP-DD form factor. EdgeOptic's compatible matches this module's optical and electrical specifications.
Four CWDM wavelengths (1271/1291/1311/1331 nm), EML transmitters, PIN receivers. PAM4 modulation at 4x106.25 Gbps for 400G aggregate throughput. LC duplex connector, OS2 single-mode fiber, 2 km maximum reach. Budget: 4.0 dB (TX -3.3 to +3.5 dBm, RX -7.3 dBm). Under 11W power consumption. KP4 FEC (RS(544,514)) required on the host side. DOM supported via CMIS 4.0 for per-lane optical monitoring. 0 to 70 C commercial operating temperature. The module negotiates 400GAUI-8 electrical signaling with the host ASIC at CEI-56G-VSR-PAM4 levels. Full specs on the 400GBASE-FR4 product page.
HG Genuine (Genuine Optics/Genuine Optronics) operates at significant volume in the transceiver market, less visible than Finisar or Broadcom but with modules running in production at major data center operators across telecom and cloud worldwide. Their product range spans multiple form factors and data rates, from 10G SFP+ through 400G QSFP-DD.
EdgeOptic codes this compatible for the specific switch platform -- Cisco, Arista, Juniper, Huawei, and others. Specify the vendor when ordering and EdgeOptic pre-programs the EEPROM. On Cisco gear, Cisco-recognized EEPROM is used so Nexus and Catalyst accept it without CLI workarounds or unsupported-transceiver warnings. IEEE 802.3cu-2021 compliant.
The MQD-56F2C-1 sometimes appears factory-installed in equipment from certain OEMs and system integrators. When replacing a failed unit, verify the exact part number from the installed module -- HG Genuine uses similar-looking numbers for different 400G variants. For example, MQD-F2F2C is a completely different QSFP-DD product with different optical characteristics. Don't swap part numbers. EdgeOptic's compatible matches the MQD-56F2C-1 optical and electrical interface precisely for a direct drop-in replacement.
Don't confuse MQD-56F2C-1 with MQD-F2F2C -- different products entirely. Always verify the exact part number from installed equipment inventory before ordering. IEEE 802.3cu-2021, QSFP-DD MSA, CMIS 4.0 compliant. RoHS certified.
