Lenovo compatible 46C3447 Description
46C3447 originated as an IBM part number for a 10GBASE-SR SFP+ transceiver and carried over into the Lenovo server portfolio after the x86 server division acquisition. The module appears in compatibility matrices for System x3550, x3650, ThinkSystem SR630, SR650, and Flex System chassis with 10G mezzanine cards. Both the IBM and Lenovo documentation reference the same 46C3447 SKU, so the part number applies regardless of whether the server still runs IBM or updated Lenovo firmware.
EdgeOptic's compatible 46C3447 is built on the 10G-SFP-300 platform. The transmitter is an 850 nm VCSEL with a PIN photodiode receiver, delivering 6.1 dB minimum link budget. Supported reach is 300 m on OM3 fiber and 400 m on OM4, through duplex LC/UPC connectors conforming to SFF-8431/8432. Data rate coverage spans 1.25 to 10.3125 Gbps, handling both 10GbE and GbE on dual-rate server NICs. The module conforms to IEEE 802.3ae for 10GBASE-SR operation.
DDM is enabled and reports TX/RX optical power, laser bias current, module temperature, and supply voltage. These values are readable through Lenovo XClarity Controller or standard SNMP polling on the server's network adapter, depending on adapter model and firmware revision. The module operates at 0 to 70 °C and is CE/RoHS certified. EEPROM is programmed with Lenovo/IBM-recognized vendor fields for seamless detection on both legacy IBM and current Lenovo firmware revisions.
When replacing OEM modules in an existing Lenovo server cluster, the compatible 46C3447 can be mixed with original IBM-branded units on opposite ends of a 10G link without optical-layer issues. Each module goes through EdgeOptic's production EdgeOptic validates each module against Lenovo server NIC firmware before shipping, confirming correct vendor ID reporting and DDM register access.

Frequently Asked Questions
Is the 46C3447 compatible with both IBM System x and Lenovo ThinkSystem servers?
Yes. 46C3447 is the same part number across both the legacy IBM System x and current Lenovo ThinkSystem product lines. EdgeOptic's compatible module has EEPROM fields that are recognized by both IBM and Lenovo firmware, so it works in System x3550/x3650 as well as ThinkSystem SR630/SR650 without configuration changes.
Can DDM data from the 46C3447 be read through Lenovo XClarity?
DDM readout depends on the server's network adapter and firmware version. On adapters that support transceiver diagnostics, OS-level NIC driver (ethtool, Intel PROSet). XClarity Administrator displays TX/RX power, temperature, bias current, and voltage. The compatible module exposes the same I2C diagnostic registers as the OEM 46C3447.
