Dell AA075998 Compatible 1000BASE-LX SFP

EdgeOptic's AA075998 compatible is a Dell-coded version of the EdgeOptic 1.25G-SFP-20D multi-vendor 1000BASE-LX 20 km transceiver. Dell catalogs the AA075998 as a 10 km 1000BASE-LX SFP accessory in its product catalog, sold under Dell's AA-prefix accessory ordering code; the EdgeOptic compatible covers the full 20 km reach class of the underlying 1.25G-SFP-20D, so it qualifies for both the OEM 10 km use case and extended 20 km Dell deployments on a single coded build.

The EdgeOptic 1.25G-SFP-20D delivers IEEE 802.3z 1000BASE-LX on 9/125 µm single-mode fiber via duplex LC connectors at 1310 nm, with a 1260 to 1360 nm wavelength band. Transmit power is −9 to −3 dBm and receiver sensitivity is −24 dBm with a −3 dBm overload limit, giving 15 dB of link budget that extends practical reach to 20 km on standard G.652 fiber. The transceiver runs Gigabit Ethernet at 1.25 Gbps over the 0 to 70 °C commercial temperature range, draws power from a +3.3 V single supply, and exposes DDM/DOM telemetry so the host switch or appliance firmware can read live TX power, RX power, bias current, supply voltage, and module temperature.

AA075998 is a Dell accessory catalog ordering code, distinct from Dell's networking-division SFP-1G part numbers. The AA-prefix groups various Dell-resold transceiver accessories under separate ordering codes, with each code covering a different optical class; nearby codes such as AA075994 and AA075999 cover different reach or rate variants, so confirm the exact AA-suffix on the original part before substituting. Engineers sourcing a replacement should verify that the target Dell appliance or switch lists AA075998 in its accessory matrix; the EdgeOptic compatible is Dell-EEPROM coded to match this ordering code and answers the same 1310 nm 1000BASE-LX SMF use case at the 20 km reach class.

This AA075998 compatible is one EEPROM build of the EdgeOptic 1.25G-SFP-20D platform, a single 1000BASE-LX 1310 nm 20 km SMF transceiver that ships under multiple vendor codings. The hardware is INF-8074i SFP MSA compliant, hot-pluggable, CE marked, RoHS compliant, and Class 1 laser safe per IEC 60825-1 and FDA 21 CFR 1040, so the EdgeOptic catalog covers the same optical build under Cisco, Juniper, Arista, HPE, Hirschmann, PLANET, Brocade, Check Point, and other vendor ordering codes for 1000BASE-LX 20 km SMF.
