HG Genuine compatible MTRQ-4ZA81 Description

MTRQ-4ZA81 is HG Genuine's part number for a 100GBASE-ZR4 QSFP28 — 100G over 80 km single-mode. HG Genuine is an OEM transceiver manufacturer whose modules ship embedded inside third-party network hardware. Their optics appear in many deployed networks without the end user necessarily knowing the origin. EdgeOptic's compatible matches the original specs and is recoded for multi-vendor platform use.

Four LAN WDM channels — 1295.56, 1300.05, 1304.58, 1309.14 nm — 25G each, 103.125 Gbps total. EML transmitters with PIN+SOA receivers. Sensitivity better than -26.9 dBm for a 30 dB link budget on G.652 fiber. LC duplex, QSFP28 MSA, approximately 5.5 W. Commercial temp 0-70 °C, CE/RoHS certified. Standard specifications for the ZR4 class — fully interoperable with any compliant ZR4 at the far end. The cooled EML lasers include integrated TEC controllers for wavelength stability.

RS-FEC (RS-528,514) on the host — mandatory, like every ZR4 module. No internal FEC in the transceiver. Most modern platforms enable RS-FEC by default for ZR4 interfaces, but always verify both ends during commissioning. Mismatched FEC prevents link establishment.

HG Genuine's modules ship as OEM stock inside other vendors' boxes. The original MTRQ-4ZA81 was qualified for one specific platform — a common scenario when a failed switch reveals an HG Genuine part number during replacement. EdgeOptic's version is recoded so the host switch recognizes it regardless of brand. Optically, it follows the same 100GBASE-ZR4 LAN WDM design used across the entire ZR4 class.

DOM operates through the standard QSFP28 I2C interface — TX/RX power, temperature, voltage all readable from the NMS. On 80 km spans, this data is critical. Detecting slow fiber degradation early is the difference between a planned maintenance window and an unscheduled outage.

Short spans (under about 15 km): add a 12 dB LC attenuator to prevent receiver overload. On the long end, 80 km on G.652 SMF with no amplification or dispersion compensation — RS-FEC must be on and total link loss must stay inside the 30 dB budget.

Frequently Asked Questions

What switch platforms was the HG Genuine MTRQ-4ZA81 originally qualified for?

HG Genuine manufactures OEM modules that ship inside other vendors' equipment, so the original platform isn't publicly documented. EdgeOptic's version is recoded for multi-vendor use. To track down the original OEM application, contact our sales team.

Is RS-FEC required for the MTRQ-4ZA81?

Yes, mandatory. RS-FEC (RS-528,514) on the host — the module doesn't do FEC itself. Confirm both ends match before commissioning.

Is the MTRQ-4ZA81 the same as a generic 100GBASE-ZR4 QSFP28?

Optically and electrically, yes. Same 100GBASE-ZR4 LAN WDM standard. MTRQ-4ZA81 is HG Genuine's internal part number. EdgeOptic's compatible is recoded so the host switch recognizes it as a supported optic rather than an unknown OEM module.
