Dell (Force10) compatible SFP-10G-USR Description
EdgeOptic's SFP-10G-USR compatible is a Dell Force10-coded Ultra Short Reach 10GBASE-SR-class SFP+ for Force10 10GbE SFP+ cages. USR is a vendor-specific short-reach variant that trades reach for cost and power. VCSEL launch power and the overall link budget are reduced relative to the IEEE 802.3ae Clause 52 SR part. Qualified multimode reach is 100 m on OM3, not the 300 m of a standard 10GBASE-SR optic. USR suits intra-rack or adjacent-rack runs; a cross-row run that needs the full 300 m OM3 reach calls for the standard SFP-10G-SR SKU instead.
Optical stage runs at 10.3125 Gbps serial line rate with an 850 nm VCSEL transmitter and an 850 nm PIN photodiode receiver, framed under IEEE 802.3ae signalling. VCSEL launch power and the overall link budget are reduced relative to the IEEE 802.3ae Clause 52 SR specification; the exact budget is defined by the Dell Force10 SFP-10G-USR datasheet, and this reduction explains the shorter USR reach. Qualified reach is 100 m on OM3 over a duplex LC multimode interface; OM4 and OM2 USR reach figures are not part of the standard USR specification and should be verified against the installed fiber plant. Mechanical envelope is the SFP+ MSA (SFF-8432) with SFF-8472 digital diagnostics for TX power, RX power, laser bias current, supply voltage and case temperature. On FTOS the diagnostic page is readable through 'show interfaces transceiver' on the SFP+ host port, under the same Force10 view as a factory Dell optic.
EdgeOptic programs the EEPROM with Dell Force10 identifiers so FTOS on the S4810, S4820T, S4048-ON and related Force10 SFP+ platforms registers the module as a native SFP-10G-USR at port bring-up. USR uses the same SFP+ cage as standard SR and plugs into any Force10 SFP+ host port. Verify the fiber span is within the 100 m OM3 budget at commissioning. The module conforms to the SFP+ MSA and is CE/RoHS certified. For intra-rack USR versus inter-row SR planning on an S4048-ON refresh, or for bulk pricing on a distributed Force10 10GbE rollout, please contact our sales team.
Frequently Asked Questions
What reach does SFP-10G-USR deliver on OM3 fiber?
100 m on OM3. USR is an Ultra Short Reach variant of 10GBASE-SR with reduced VCSEL launch power and a tighter link budget relative to the IEEE-specified SR part; the exact figure is defined in the Dell Force10 SFP-10G-USR datasheet. For runs that require the full 300 m OM3 reach, use the standard 10GBASE-SR SKU rather than USR.
Does SFP-10G-USR work in a standard 10GBASE-SR SFP+ cage?
Yes. USR uses the same SFP+ MSA mechanical and electrical interface as the standard SR part, and plugs into any Force10 10GbE SFP+ host port that accepts SR. The difference is at the optical layer: reduced launch power and a shorter reach budget, not a different physical form factor.
Which Force10 chassis accept SFP-10G-USR?
Dell Force10 S4810, S4820T, S4048-ON and related Force10 SFP+ platforms that list SFP-10G-USR in the qualified-optic set. FTOS exposes the SFF-8472 diagnostic page through 'show interfaces transceiver' on the SFP+ host port.
