HG Genuine compatible MTRQ-4ZA81 Description

EdgeOptic's MTRQ-4ZA81 compatible is an HG Genuine-coded 100GBASE-ZR4 QSFP28 rated for 80 km on G.652 single-mode fiber. HG Genuine is an OEM optical transceiver manufacturer; MTRQ-4ZA81 is the HG Genuine designation for this 80 km QSFP28 ZR4 module and the part number that surfaces when an OEM-branded 100G optic is pulled from a host platform during replacement. The EdgeOptic compatible matches the original optical specs and ships with multi-vendor EEPROM coding for use across third-party 100G QSFP28 host platforms.

Four LAN-WDM channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, 25.78 Gbps each lane, 103.125 Gbps aggregate over two single-mode fibers (TX and RX) on an LC duplex connector. Cooled EML transmitters, SOA + PIN photodetector array, 30 dB optical link budget on G.652 fiber. NRZ direct-detection, DOM via the standard QSFP28 I2C interface. 100GBASE-ZR4 is MSA-extended from IEEE 802.3ba LR4 to reach 80 km.

Host RS-FEC is mandatory. ZR4 closes the 80 km link with RS(528,514) per IEEE 802.3 Clause 91 running on the host MAC; the module carries no internal FEC. Both ends must have RS-FEC enabled, otherwise the link will not stabilise. The default RS mode is correct on most modern 100G ZR4 host platforms; verify the FEC setting per port during commissioning.

100G ZR4 80 km optics serve ISP backbone aggregation, metro core links, mobile core transport, and data centre interconnect spans where 40 km LR4 is too short and coherent ZR is more module than the budget needs. The EdgeOptic MTRQ-4ZA81 compatible is the replacement path when the original HG Genuine module fails or when a multi-vendor recoded variant is required for use outside the original OEM-branded chassis.

Operating temperature 0 to +70 °C commercial grade. DOM via standard QSFP28 I2C exposes TX/RX power, temperature, and supply voltage to the host NMS, which matters on 80 km spans where slow fiber-plant degradation is the difference between a planned maintenance window and an unscheduled outage. On short spans under about 15 km the receiver can saturate on the upper end of the ZR4 TX range; insert a 12 dB LC inline attenuator on the receive side. Sibling Cisco QSFP-100G-ZR4-S, Arista QSFP-100G-ZR4, Hisense LTA1319-PC1, and Edgecore ET7402-ZR4 compatibles cover the same 80 km LAN-WDM ZR4 standard with vendor-coded EEPROM for those host platforms.

Frequently Asked Questions

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

HG Genuine is an OEM transceiver manufacturer whose modules ship into other vendors' branded equipment, so the original platform qualification is not publicly documented for MTRQ-4ZA81. The OEM-side EEPROM is typically coded for whichever host the original system vendor qualified the part on. The EdgeOptic compatible carries multi-vendor EEPROM coding so the same optic is recognised across third-party 100G QSFP28 host platforms that support 100GBASE-ZR4 with host-side RS-FEC. To match the EdgeOptic MTRQ-4ZA81 to a specific chassis you have in production, the host system vendor's transceiver matrix is the authoritative source.

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

Optically and electrically, yes. MTRQ-4ZA81 follows the same 100GBASE-ZR4 LAN-WDM design used across the ZR4 80 km class: four channels at 1295.56 to 1309.14 nm, 25.78 Gbps each lane, EML transmitters with SOA + PIN photodetectors, 30 dB optical budget, host RS-FEC. The MTRQ-4ZA81 part number is HG Genuine's internal designation for the OEM build. The EdgeOptic compatible matches that spec with multi-vendor EEPROM coding so it is recognised on third-party 100G QSFP28 host platforms that support ZR4 with host-side RS-FEC.
