Cisco SFP-10G-LR-S 10GBASE-LR SFP+ Transceiver
1310nm 10GbE SFP+ optic for single-mode fiber spans up to 10km. Confirm exact product label and revision before applying specifications.
IDENTIFICATION: Confirm manufacturer PID, hardware revision, device ID or module suffix. Nominal standards/link rates are not measurements of payload performance.
Exact specifications and compatibility
| Dedicated subcategory | SFP transceivers: optical and copper |
|---|---|
| Exact product/model | Cisco SFP-10G-LR-S 10GBASE-LR SFP+ Transceiver |
| Bus, ports and physical interface | Hot-pluggable SFP+ with duplex LC; supported 10GbE SFP+ port required. |
| PHY, radio or protocol | 10GBASE-LR at 1310nm over standard SMF (G.652); S suffix is Cisco PID distinction and host support remains platform-specific. |
| Nominal rate (not measured) | 10Gb/s nominal; up to 10km manufacturer link reach, not measured throughput. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | No host driver; Cisco platform software and transceiver matrix must list exact SFP-10G-LR-S PID. |
| Compatibility | Use duplex SMF and matched 1310nm LR at both ends; assess optical loss and short-span receiver budget. |
| Variant warning | LR-S is distinct from SFP-10G-LR, LR-X and LR-I; PID suffix denotes qualification/feature differences. Verify Cisco host compatibility. |
Model and revision notes
LR-S is distinct from SFP-10G-LR, LR-X and LR-I; PID suffix denotes qualification/feature differences. Verify Cisco host compatibility.
No host driver; Cisco platform software and transceiver matrix must list exact SFP-10G-LR-S PID.
Use duplex SMF and matched 1310nm LR at both ends; assess optical loss and short-span receiver budget.
Archival, ESD and preservation notes
Record exact suffix, serial, DOM, host and fiber plant; cap/clean LC and store antistatically.
Document source URL, access date, document revision and specimen label/condition. Preserve without credentials or private configuration.
