StarTech.com J4859C10PKST — HPE 1G LX SFP, Pack of 10
10 modules1000BASE-LXHPE J4859C codedUp to 10 km
The StarTech.com J4859C10PKST is a pack of ten Gigabit SFP transceivers for single-mode fibre, reaching up to 10 km at 1310 nm over LC duplex connections. Each module is programmed as an HPE J4859C and supports digital diagnostics, so the pack suits campus rollouts and spare stock across HPE switches. In practice, single-mode optics are the choice when a link leaves the building or runs several hundred metres: the OS2 fibre used by carriers and campus backbones carries the signal for kilometres with little loss. Before you order, confirm the fibre is single-mode at both ends and note the length and the number of patch panels on the way.
Compatibility — check before buying:
This article is ten modules; the single module is J4859CST. The 10 km reach is for single-mode fibre. StarTech labels it single/multi mode but gives no multimode reach, so for multimode runs choose the SX J4858C10PKST. It is a 1G optic coded for HPE J4859C. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your device model and the cable run and we check it before you order.

Key Features
Ten modules, one article
A 10-pack of identical 10 km LX optics for campus rollouts and spares.
Single-mode fibre, long reach
Built for single-mode (OS1/OS2) fibre, the type used between buildings, floors and sites. It will not run over the orange or aqua multimode fibre found in many racks — the fibre type has to match at both ends.
Monitoring you can read
Digital diagnostics (DDM) let the host report temperature, laser power and received light, so a dirty connector or a failing link shows up before users call.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.

Frequently Asked Questions
Singular Expert Insight
We offer the J4859C10PKST for HPE networks that span several buildings: ten LX optics cover five single-mode links. For an HPE-branded optic on current Aruba switches, the J4859D is the original part. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status and we help you find out whether it is the module, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
