Cisco SFP‑10G‑SR‑X Specifications
Product Name: Cisco SFP‑10G‑SR‑X Multi‑Rate SFP+ Transceiver
Manufacturer: Cisco
Manufacturer Model: SFP‑10G‑SR‑X
Product Type: Optical Transceiver Module (SFP+)
Product Series: 10GBASE‑SR, Multi‑Rate (10 Gbps)
KEY FEATURES:
Form Factor: SFP+ (small form‑factor pluggable)
Supported Data Rates: Up to 10 Gbps (10GBASE) and compatible multi‑rate operation
Media Type: Multimode Fiber (MMF)
Wavelength: 850 nm nominal
Connector Type: Duplex LC optical connector
Hot‑swappable: Yes — supports insertion and removal without powering down the system
Digital Optical Monitoring (DOM) support recommended
PERFORMANCE / LINK DISTANCES:
Over OM3 MMF (50 µm core, 2000 MHz·km modal bandwidth), supports up to ~300 m
Over OM4 MMF (50 µm core, 4700 MHz·km modal bandwidth), supports up to ~400 m
Minimum reach on older fiber such as 62.5/125 µm or OM1/OM2 fibers: shorter
ENVIRONMENTAL & RELIABILITY:
Operating Temperature Range (commercial grade): 0 °C to 70 °C
Typical Power Consumption: ~1 W
Module Type: Pluggable into SFP+ port of Cisco switches, routers, and other networking hardware supporting 10 Gbps SFP+ optics
PHYSICAL / MECHANICAL:
Pin‑out and mechanical dimensions follow SFP+ (MSA) form factors: approx 2.75″ × 0.5″ × 0.4″
LC duplex connector (supports twin optical fibers)
APPLICATION NOTES:
Ideal for short‑range 10 Gbps links within data centers, server rooms, or high‑density installations using multimode fiber
To achieve full 300‑400 m distances, use OM3 or OM4 fiber—less capable fiber like OM1/OM2 will shorten reach significantly
Ensure compatibility with your network hardware: modules from third‑party vendors should match Cisco compatibility if used in Cisco gear
