This HP® J4858D compatible SFP transceiver provides 1000Base-SX throughput up to 550m over multi-mode fiber (MMF) using a wavelength of 850nm via an LC connector. It can operate at temperatures between 0 and 70C. Our transceiver is built to meet or exceed OEM specifications and is guaranteed to be 100% compatible with HP®. It has been programmed, uniquely serialized, and tested for data-traffic and application to ensure that it will initialize and perform identically. All of our transceivers comply with Multi-Source Agreement (MSA) standards to provide seamless network integration. Additional product features include Digital Optical Monitoring (DOM) support which allows access to real-time operating parameters. This transceiver is Trade Agreements Act (TAA) compliant. We stand behind the quality of our products and proudly offer a limited lifetime warranty. Technical Specification Compatible OEM That's to say that using OM3 MMF or, better, OM4 MMF cables helps enhancing overall performance of optical signals and, probably, considering that, a valuable length can unofficially gained over the official 550 meters threshold value...but not so long (at some point shifting to SMF over MMF become a must if you have a long run) and nothing in that territory, in term of admissible official working values, should be taken for granted (somewhere - here as example - I saw reported a maximum distance of maybe 800/1000 meters, at best...and those values are not related to an Aruba SFP 1G SR Transceiver...indeed those values are not coming from something tested and declared by Aruba as per published standards...and indeed Aruba doesn't report those values too, see here a discussion about what is granted and what's not on MMF with SFP SR Aruba Transceivers). For use in the SFP ports on the models listed. Also for use in the dual-speed SFP⁠+ ports of the J9731A 2-Port 10GbE SFP⁠+ Module. The JL687A module requires configuration of "interface groups" (groups of 4 ports) to enable the use of 1G or 10G transceivers / DACs in the SFP28 ports (default is to use 25G transceivers / DACs).

The 8325 requires configuration of "interface groups" (groups of 12 ports) to enable the use of 1G or 10G transceivers / DACs in the SFP28 ports (default is to use 25G transceivers / DACs). R0X44C has the added feature of enabling the bottom ports to accept a 50G product, and in this mode, will NOT accept these 1G transceivers(see 50G SFP56 chapter).For use in the JL075A 3810M switch. Also for use in any 3810M switch with a JL083A Aruba 3810M/2930M 4SFP⁠+ MACsec Module installed.

For use in the SFP ports on the models listed, and in an installed J9312A 10GbE 2-port SFP⁠+/2-port CX4 yl ModelThe 8360 32Y4C and 48Y6C models require configuration of "interface groups" only for ports 1-4 (as group #1) to enable the use of 10G transceivers / DACs in the SFP28 ports (Interface Groups default to 25G speed). Ports 1-4 on the 8360 32Y4C model do not support 1G transceivers. ER (J9153A/D) transceivers are limited to a maximum of two transceivers per J9309A or J9538A modules when used in a 5400zl or 8200zl chassis. JL687A 32p 25G module requires configuration of "interface groups" (groups of 4 ports) to enable use of 1G or 10G transceivers or DACs in the SFP28 ports (Interface Groups default to 25G speed). See the Installation Guide for details. For sure at the very same maximum distance capable when using tested OM2 MMF cables (50/125 um 850 nm), so up to 550 meters.
