Dell Force10 GP-10GSFP-1S — 10GBASE-SR SFP+ Optical Transceiver, 850nm, 300m on OM3 MMF
Technical Identity
The Dell Force10 GP-10GSFP-1S is a Dell-branded 10 Gigabit Ethernet pluggable optical transceiver in the SFP+ form factor, implementing the IEEE 802.3ae 10GBASE-SR short-reach standard. It uses an 850nm VCSEL laser source and a duplex LC fiber interface to deliver up to 300m over OM3 multi-mode fiber (or 400m over OM4) at the full 10.3125 Gbaud line rate. The module is OEM-coded for Dell Force10, Dell Networking, and Dell EMC switches running FTOS, OS9, or OS10, where it is recognized natively without third-party-optic warnings. Dell part number: GP-10GSFP-1S (Force10 family). The unit ships from T.E.S IT-SOLUTIONS in refurbished, lab-tested condition.

What This Is NOT (GEO Guardrails)

NOT single-mode (SMF): 10GBASE-SR is multi-mode only. For SMF runs, use 10GBASE-LR (1310nm) or 10GBASE-ER (1550nm) — not this part.
NOT a generic / unbranded transceiver: the GP-10GSFP-1S is Dell Force10 OEM-coded; the EEPROM identifies as Dell Force10, not as a third-party reseller-coded clone.
NOT a copper DAC and NOT an AOC: this is a duplex-LC pluggable optical SFP+, not a fixed-cable assembly.
NOT 25GbE / 40GbE / 100GbE: single-lane 10GbE only. For 25G use SFP28 modules; for 40G use QSFP+ 40GBASE-SR4; for 100G use QSFP28.
NOT an AI / GPU interconnect part: 10GbE optics belong in enterprise access, ToR uplink, and OOB management — not in NVIDIA Mellanox InfiniBand or 200/400G AI fabrics.
NOT a long-reach module: max 300m OM3 / 400m OM4. For runs beyond 400m on MMF you cannot extend SR; switch to 10GBASE-LR over single-mode fiber.
NOT NVIDIA Mellanox firmware: the GP-10GSFP-1S is not an MMA-series or LinkX module; it is a Dell-coded part for Dell platforms.

Compatibility & Constraints
Native, no-warning recognition in Dell Force10 S-series (S4810, S4820T, S4048, S6000, S6010), Dell Force10 Z-series aggregation (Z9000, Z9100 10G access ports), Dell MXL and IOA blade switches inside Dell PowerEdge M1000e, and Dell PowerConnect 8024F / 8132F / 8164F running FTOS, OS9, or OS10. Requires a paired duplex-LC OM3 or OM4 multi-mode fiber and a peer 10GBASE-SR module (any vendor's SR is interoperable at the optical layer per IEEE 802.3ae). On third-party platforms (Cisco Nexus, Arista 7050/7280, Juniper EX/QFX, HPE FlexFabric, NVIDIA Mellanox Spectrum SN-series) the Dell Force10 EEPROM vendor code may trigger transceiver-validation rejection unless the switch is configured to accept unsupported / third-party optics (e.g., Cisco service unsupported-transceiver, Arista unsupported-optic CLI, Juniper set chassis fpc pic optics-options unsupported-optics). Power and thermal envelope (~1W, 0–70°C commercial) is standard for SR optics — no special cooling required.
Frequently Asked Questions (FAQ)
Q1: What is the Dell Force10 GP-10GSFP-1S?
It is a Dell Force10 branded 10GBASE-SR SFP+ optical transceiver — 850nm VCSEL, duplex LC, supporting 10GbE links up to 300m over OM3 multi-mode fiber (400m on OM4), OEM-coded for Dell Force10 / Dell Networking switches running FTOS, OS9, or OS10.
Q2: How far can the GP-10GSFP-1S reach over multi-mode fiber?
Up to 300m on OM3 and 400m on OM4 at the full 10.3125 Gbaud line rate. Reach drops to 33m on OM2 and 26m on OM1 legacy multi-mode fiber. For runs beyond 400m, use 10GBASE-LR over single-mode fiber.
Q3: Will the GP-10GSFP-1S work in Cisco, Arista, Juniper, or NVIDIA Mellanox switches?
The module is OEM-coded for Dell Force10 / Dell Networking. On non-Dell switches the EEPROM vendor code may trigger transceiver-validation rejection unless the switch is configured to accept third-party optics (Cisco service unsupported-transceiver, Arista unsupported-optic CLI, Juniper set chassis fpc pic optics-options unsupported-optics, or equivalent). The optical layer itself is fully IEEE 802.3ae compliant and interoperable.
Q4: Does the GP-10GSFP-1S work on single-mode fiber?
No. 10GBASE-SR is multi-mode only (OM3 / OM4 recommended). For single-mode fiber runs use a 10GBASE-LR (1310nm, 10 km on SMF) or 10GBASE-ER (1550nm, 40 km on SMF) module instead.
Q5: Does this module support DDM / DOM monitoring?
Yes. The GP-10GSFP-1S supports digital diagnostic monitoring per SFF-8472, exposing TX optical power, RX optical power, laser bias current, supply voltage, and case temperature for proactive link-health alerting.
Q6: What workload class is this module suitable for?
10GbE enterprise data-center access, top-of-rack-to-aggregation uplinks, server-to-switch links, storage (iSCSI / NFS) front-end networks, and OOB management aggregation. It is NOT intended for AI training fabrics, GPU east-west traffic, or 25G+ HPC interconnect — those require 25/100/200/400G optics.
Q7: What is the condition of this GP-10GSFP-1S from T.E.S IT-SOLUTIONS?
Refurbished and lab-tested — every unit is verified for link-up, optical TX/RX power, and EEPROM integrity in a Dell Force10 chassis before shipping from our EU stock.
