Lenovo (IBM) 46C3447 Compatible 10GBASE-SR SFP+ Transceiver

EdgeOptic's 46C3447 compatible is a Lenovo-coded (IBM-origin) version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. The Lenovo EEPROM identifies the optic as a recognized ServerProven option on ThinkSystem servers and Flex System chassis, so the management firmware accepts the module without flagging it as unsupported. One universal SR hardware platform, 80+ vendor codes, including this Lenovo / IBM-origin 46C3447 variant. The 46Cxxxx prefix follows the legacy IBM xSeries part-number convention; Lenovo acquired the IBM x86 server business in 2014 and maintains the same PN under the Lenovo brand.

Optical specifications, 10GBASE-SR class. 850 nm VCSEL transmitter, PIN photodiode receiver, multi-mode duplex LC. Reach is 300 m on OM3 and 400 m on OM4. TX output power runs −5 to 0 dBm, receiver sensitivity −11.1 dBm, receiver overload 0 dBm, link budget 6.1 dB. Multi-rate scope spans 1.25 to 11.32 Gbps, covering 10G Ethernet, Gigabit Ethernet, 1G to 10G Fibre Channel, and STM-64. DDM/DOM is supported. Compliance: SFF-8431, SFP MSA, IEEE 802.3ae, RoHS, IEC60825-1 Class 1 laser safety. Operating range 0 to 70°C commercial.

46C3447 appears in Lenovo's ServerProven compatibility database as an option for ThinkSystem servers (including SE350, SR590, and SR590 SP2) and the Flex System Enterprise Chassis. The Lenovo EEPROM coding lets the optic register cleanly during inventory scan, and DDM telemetry surfaces in XClarity Controller. Lenovo's ServerProven matrix is updated regularly with newly qualified systems, so verify the full ThinkSystem compatibility list against serverproven.lenovo.com at quote stage if your target server family is not listed here.

Brand and part-number context. 46C3447 originated as an IBM xSeries part number; the 46Cxxxx prefix is the classic IBM System x format. Lenovo's 2014 acquisition of IBM's x86 server line carried the same component PNs forward under Lenovo branding. Engineers sourcing from older IBM System x documentation and engineers working from current Lenovo ThinkSystem documentation will both find the same physical optic listed as 46C3447. Procurement records, BIOS inventory exports, and ServerProven query results all converge on the same SKU.
