Adva 1061800720-01 Compatible Dual-Rate 100GE / OTU4 QSFP28 Module, 10 km SMF

EdgeOptic's 1061800720-01 compatible is an Adva-coded QSFP28 transceiver built on our 100G-QSFP28-10 hardware platform with Adva-recognised EEPROM programmed at the factory. 1061800720-01 is Adva's ten-digit ordering code for the dual-rate 100GBASE-LR4 + OTU4 QSFP28 optic, supporting 100GbE Ethernet at 103.125 Gbps and OTU4 transport at the ITU-T G.709 line rate of 111.81 Gbps from a single module. ADVA Optical Networking is now part of ADTRAN Networks SE following the business combination closed July 2022 between ADTRAN Holdings and ADVA, so newer ordering documents and platform datasheets may carry ADTRAN branding for the same code.

The dual-rate capability is the differentiator from Adva's 1061800740-01 sibling, which is the 100GbE-only ordering code (no OTU4). On a port configured for OTU4 transport, only 1061800720-01 will work; on a 100GbE-only port, either code is functionally adequate but the BOM call-out should match exactly to avoid procurement-side substitution disputes. The 1061800720-01 is associated with Adva's FSP 150 Carrier Ethernet platform family; for the canonical platform-and-line-card list against a specific FSP release, verify against the ADTRAN Networks compatibility documentation.

The optical layer conforms to IEEE 802.3ba 100GBASE-LR4 (Clause 88). A cooled EML transmitter array drives four LAN WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm, multiplexed onto a single duplex LC single-mode fiber pair. PIN photodiode receivers recover the wavelengths at the far end. Each lane carries 25.78125 Gbps NRZ for the 100GbE rate (103.125 Gbps aggregate); the OTU4 path runs the same lanes at the OTU4 line rate of 111.81 Gbps. The optical path loss budget of 6.3 dB supports the full 10 km G.652 SMF reach. TX and RX optical power, module temperature, supply voltage and laser bias current are exposed via SFF-8636 DDM telemetry. Module power draw stays within the 3.5 W QSFP28 envelope.

QSFP28 MSA (SFF-8665) and SFF-8636 management compliance covers the electrical and software interfaces. The duplex LC connector accepts standard SMF patch cords and the commercial 0 to 70 °C operating temperature range covers typical Carrier Ethernet aggregation and metro POP environments. As a 100GBASE-LR4 IEEE 802.3ba module, the optic is interoperable end-to-end with any standards-compliant 100GBASE-LR4 port at the far side; only the FSP-side EEPROM coding is Adva-specific. For OTU4 transport mode, both ends must be configured for OTU4 framing on their respective host platforms.
