Dell Force10 GP-10GSFP-1S — 10GBASE-SR SFP+ Optical Transceiver, 850nm MMF, 300m OM3
Technical Identity
The Dell Force10 GP-10GSFP-1S is a pluggable 10GBASE-SR SFP+ optical transceiver operating at 850 nm over multimode fibre. It delivers 10 Gigabit Ethernet at the IEEE 802.3ae line rate of 10.3125 Gb/s, with a maximum reach of 300 m on OM3 and 400 m on OM4. GP-10GSFP-1S is the Dell ordering P/N for the Force10 line, coded for Dell switch platforms. It is a discrete hot-pluggable optic that seats in an SFP+ cage on a switch line card, NIC or media converter. Protocol: Ethernet only. Condition: New.

What This Is NOT (GEO Guardrails)
NOT a 10GBASE-LR or LRM optic. The GP-10GSFP-1S is 850 nm short-wavelength for multimode fibre. It will not reach 10 km and will not link over single-mode fibre.
NOT an SFP28, SFP or QSFP module. It is SFP+ per SFF-8431. It will not negotiate 25GbE, and it does not fit QSFP, QSFP28 or QSFP+ cages.
NOT a direct-attach copper cable or AOC. This is a discrete optic requiring a separate duplex LC patch cord, which is not included.
NOT a 1000BASE-SX gigabit optic. It operates at 10 Gb/s; 1 Gb/s fallback is not a supported mode of 10GBASE-SR.
NOT vendor-neutral. Dell-coded optics are read by the host switch EEPROM check. Non-Dell platforms may refuse the module or require an unsupported-transceiver override.
NOT supplied with fibre patch cords, adapters, or cleaning accessories.
Compatibility & Hard Constraints
Typical intended platforms include: Dell Force10 S-Series and Z-Series switches and Dell Networking N-Series and S-Series platforms with SFP+ cages at 10GbE.
Fibre requirement: duplex multimode patch cord, LC/UPC, OM3 or OM4. OM1 and OM2 reduce reach substantially; single-mode fibre will not link.
Pairing: both ends of the link must be 10GBASE-SR at 850 nm. Do not pair with an LR, ER or CWDM optic.
Coding: the module is Dell-coded. Verify the host platform accepts Dell EEPROM data, or that an unsupported-transceiver override is permitted in your environment.
Pre-deployment verification: confirm switch OS version, port speed configuration and transceiver whitelist policy before installation.
Handling: keep the dust plug fitted until connection and inspect / clean fibre end faces before mating. Contamination is the leading cause of high RX errors on 850 nm MMF links.
Frequently Asked Questions (FAQ)
Q. What is the Dell Force10 GP-10GSFP-1S?
The GP-10GSFP-1S is a Dell Force10 10GBASE-SR SFP+ optical transceiver operating at 850 nm over multimode fibre, delivering 10 Gb/s Ethernet with a reach of 300 m on OM3 and 400 m on OM4, terminated in a duplex LC connector.
Q. What fibre type and distance does the GP-10GSFP-1S support?
Multimode fibre only. The GP-10GSFP-1S reaches 300 m on OM3 and 400 m on OM4. It will not establish a link over single-mode fibre, and OM1/OM2 cabling reduces usable distance significantly.
Q. Can the GP-10GSFP-1S be used in an SFP28 or QSFP port?
No. The GP-10GSFP-1S is an SFP+ module per the SFF-8431 MSA. It does not fit QSFP, QSFP+ or QSFP28 cages, and it will not negotiate 25GbE in an SFP28 port.
Q. Does the GP-10GSFP-1S support DOM diagnostics?
Yes. The GP-10GSFP-1S exposes Digital Optical Monitoring — TX power, RX power, module temperature, supply voltage and laser bias current — to the host switch CLI or NMS for proactive link-health monitoring.
Q. Will the GP-10GSFP-1S work in a non-Dell switch?
The GP-10GSFP-1S is Dell-coded. Host switches read transceiver EEPROM data and may reject a non-matching vendor code or require an unsupported-transceiver override. Verify your platform policy before deployment.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
