IBM compatible 88Y6416 Description
EdgeOptic's 10G-SFP-300 compatible is an IBM-coded 10GBASE-SR SFP+ transceiver that replaces the 88Y6416 FRU. The 88Y prefix belongs to IBM's Flex System product line, and this part number was specified for Flex System x240 and x440 compute nodes, EN2092 1Gb/10Gb Ethernet switches, and other modules within the IBM PureFlex chassis. EdgeOptic programs the EEPROM with IBM-recognized vendor data, so the module registers as a supported optic across all Flex System components.
IBM Flex System consolidated compute, storage, and networking into a single chassis (the Flex System Enterprise Chassis, formerly PureFlex). The x240 compute node used 10 GbE SFP+ uplinks for fabric connections to the EN2092 Ethernet switch module, which then aggregated traffic toward the data center core. The x440 four-socket compute node followed the same connectivity model for higher-density workloads. The 88Y6416 was the designated FRU for all 10GBASE-SR connections inside this chassis, replacing earlier 45W-prefix optics from the BladeCenter transition era. Flex System deployments that remain in production, particularly in virtualized and private cloud environments, continue to consume 88Y6416 replacements as part of routine maintenance. The Flex System x240 compute node has two embedded 10Gb Ethernet ports plus a mezzanine slot for additional network adapters. The EN2092 switch module provides 20 internal 10Gb ports (two per compute node slot) and external SFP+ uplink ports where the 88Y6416 connects the chassis to the upstream network. IBM Flex System Fabric EN4093R 10Gb Scalable Switches also accept this FRU for their external 10G uplinks.
The optical interface uses an 850 nm VCSEL transmitter and PIN photodiode receiver over duplex LC multimode fiber. Link budget is 6.1 dB, supporting 300 m on OM3 and 400 m on OM4 cabling. DDM (Digital Diagnostic Monitoring) reports TX power, RX power, temperature, bias current, and supply voltage. The module conforms to IEEE 802.3ae 10GBASE-SR and SFF-8472 for diagnostic data, with a 0 to 70 degrees C commercial operating range.

Frequently Asked Questions
Which Flex System components use the 88Y6416 SFP+?
The 88Y6416 is the designated 10GBASE-SR SFP+ for IBM Flex System x240 and x440 compute nodes and the EN2092 1Gb/10Gb Ethernet switch module. It provides 10 GbE fabric connections between compute nodes and the Ethernet switch within the Flex System Enterprise Chassis (PureFlex).
Can the 88Y6416 be used in older IBM BladeCenter chassis?
The 88Y6416 was coded specifically for Flex System. BladeCenter chassis typically require earlier FRUs such as the 45W0500 or 22R4902, which carry different EEPROM coding. While the optical specs are identical, ordering the correct FRU for the target chassis ensures the switch module recognizes the transceiver without issues.
Is the 88Y6416 still relevant now that Lenovo owns IBM's server business?
Yes. Many Flex System deployments remain in production for virtualized and private cloud workloads. These environments still consume 88Y6416 replacements during routine maintenance. EdgeOptic's compatible uses IBM EEPROM coding, so both original IBM firmware and Lenovo-updated firmware accept the module.
