StarTech.com 3CSFP91ST — HPE 3CSFP91-Compatible 1G SX SFP
1 Gbps1000BASE-SXHPE 3CSFP91 codedUp to 550 m
The StarTech.com 3CSFP91ST is a Gigabit SFP transceiver for multimode fibre, reaching up to 550 m at 850 nm over an LC duplex connection. It is programmed as the HPE 3CSFP91 — the part that began life in the 3Com switch range — so HPE switches of that lineage such as the 3812, 3824, 3848 and 4070 accept it. It supports digital diagnostics and draws under 1 W. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
Compatibility — check before buying:
The switches StarTech.com lists are older 3Com-lineage HPE models. Current HPE Aruba switches expect their own part numbers (for example J4858C/J4858D for 1G SX), so do not assume this module fits an Aruba 2530, 2930 or CX — send us the model first. It needs multimode fibre and an SX module at the far end. 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.
Best For
✓ HPE 3800-series 3Com-lineage switches
✓ Keeping an older HPE network running
✓ 1G links inside one building
✓ Replacing HPE 3CSFP91 optics
✓ Multimode runs up to 550 m
✓ Spare optics at a lower cost
Key Features
Coded for HPE 3CSFP91
Programmed as the HPE 3CSFP91, so the 3Com-lineage HPE switches that expect that part accept it.
Multimode fibre, short reach
Built for the short runs inside a building or data room over OM-grade multimode fibre. Reach depends on the fibre grade — check what is actually in your walls before you plan a link.
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 3CSFP91ST to customers who keep older 3Com-lineage HPE switches in service and need a coded 1G SX optic at a lower cost, with a lifetime module warranty. For current Aruba switches we point you to the matching Aruba-coded optic instead. 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.
Buyer’s Guide
Buy it if
You run an HPE 3812, 3824, 3848 or 4070 and need a 1G multimode optic.
Skip it if
Your switch is a current Aruba model, or your fibre is single-mode.
