Lenovo compatible 81Y1622 Description
EdgeOptic's 81Y1622 compatible is an IBM / Lenovo-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850nm VCSEL transmitter and a PIN photodiode receiver.
With a 7.5 dB optical budget, the module reaches 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m over OM1 (62.5/125). The transmitter delivers a minimum of -9.5 dBm and the PIN receiver is rated to -17 dBm sensitivity. It uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live monitoring of optical power, bias current, and temperature. The module operates over the commercial 0 to 70°C range, built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.
81Y1622 is the IBM and Lenovo ordering code for this 1G SX SFP. EdgeOptic codes the EEPROM with vendor-recognized data so the module is accepted on Lenovo and IBM Flex System switches. Because the same code spans several switch generations, check your exact chassis against the vendor's transceiver documentation before ordering.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ordering-code confirmation or platform questions, contact our sales team.
Frequently Asked Questions
Is the IBM 81Y1622 the same as the Lenovo 81Y1622?
Yes. 81Y1622 is a single ordering code that appears under both brands. It originated as an IBM System x and Flex System part, and it stayed in use under Lenovo after Lenovo acquired IBM's x86 server business, announced in January 2014 and closed in October 2014. IBM's own Flex System documentation and Lenovo's ServerProven database both reference the same part number, so an IBM-branded and a Lenovo-branded 81Y1622 are the same 1000BASE-SX SFP.
Which switches does the 81Y1622 SFP work with?
Lenovo's ServerProven database lists the 81Y1622 across the Flex System switch family, including the Flex System Fabric EN4093 and EN4093R, CN4093, SI4093, EN4091 Pass-thru, SI4091, and the EN2092 1Gb Ethernet Scalable Switch, with the ThinkSystem SE350 listed as CTO only. The list spans several hardware generations and carries no optical spec table, so confirm your exact chassis and switch model in Lenovo's ServerProven listing before ordering.
