About this deal

For J8705A and J8706A modules: All (for J9054B/C 1990-3613); K.15.08.0007 (for J9054C 1990-4112 and 1990-4483) J9054D: K.15.08.0007 The 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. K.12.01 (for J9054B/C 1990-3613); K.15.08.0007 (for J9054C 1990-4112 and 1990-4483) J9054D: K.15.08.0007 The J4858CST is an HP J4858C compatible fibre transceiver module that has been designed, programmed and tested to work with HP® brand switches and routers. It delivers dependable 1 GbE connectivity over fibre cable, for 1000BASE-SX compliant networks, with a maximum distance of up to 550 m (1804 ft). 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.

Only supported for use in SFP⁠+ ports on JL658A. 100-FX is not supported for use in any SFP56 ports on other models.If you want to go to a longer distance you need to move to Single Mode Fiber and the matching SFP. Typically a SX or LX vs MX transceiver. For J8705A and J8706A modules: K.12.01 (for J9054B/C 1990-3613); K.15.08.0007 (for J9054C 1990-4112 and 1990-4483) J9054D: K.15.08.0007 Gig LH (J4860C/J4860D) is not supported on the 1850 series. Other 1850 models not listed do not have SFP ports. For use in the SFP ports of the J9263A 6600-24G Switch, the J9264A 6600-24G-4XG Switch, and the J9451A 6600-48G Switch

Hi Temp warnings will trigger at lower temperatures (~50C)if Commercial Temp vs Industrial Temp transceivers (~70C) are used. All Third Party transceivers are treated as Commercial Temp, regardless of capability.

For J8692A, J8693A: K.12.01 (for J9054B/C 1990-3613); K.15.08.0007 (for J9054C 1990-4112 and 1990-4483, and J9054D 1990-4483 and 1990-4360) A 300 meters run, especially deployed with OM3 MMF, should be an easy run for two J4858D so I believe you can expect 1Gbps Full Duplex without issues if optical cabling and patches is correctly deployed, tested and so certified. The 8325 requires configuration of "interface groups" (groups of 12 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. So first you need to understand that multimode fiber is named that way for a reason. There are multiple modes of light that are sent over the cable, so when light is transmitted it looks something like this: Not supported for use in the following 3800 models: J9573A, J9574A, J9575A, and J9576A. The SFP⁠+ ports do not support 100M operation.

The 8325 requires configuration of "interface groups" (groups of 12 ports) to enable use of 1G or 10G transceivers or DACs in the SFP28 ports (default is to use 25G transceivers / DACs). See the The 2930F Switch Series models with 1G/10G SFP⁠+ ports added support for this J9054C/J9054D 100FX transceiver. The J9054C/J9054D are supported in models with 1G SFP ports. For J9537A, J9549A, J9535A, and J9637A modules: K.15.02.0004 (for J9054B/C 1990-3613); K.15.08.0007 (for J9054C 1990-4112 and 1990-4483) J9054D: K.15.08.0007 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).

Customer reviews

This is called modal dispersion, it's an inherent property of multimode fiber - it's basically the relationship between distance and bandwidth. Specifically if you are using a 1GB MX (Multimode) SFP your distance is limited to 100m (330ft). You could be using the best quantum designed military grade fiber in the world and your distance limitation is still based on the timing characteristics of the MAC layer definition. This SFP fibre module is hot-swappable, making upgrades and replacements seamless by minimizing network disruptions.
