Q1: What is an SFP-10G-LR module?
A: The SFP-10G-LR is a Small Form-factor Pluggable Plus (SFP+) transceiver module designed for 10 Gigabit Ethernet (10 Gbps) transmission over single-mode fiber (SMF) using a 1310 nm DFB laser.
Q2: What is the maximum supported transmission distance?
A: Supports up to 10 km over standard single-mode fiber (G.652); actual range may slightly exceed depending on fiber quality.
Q3: What connector and fiber type does it use?
A: Uses duplex LC connector over single-mode fiber (9/125 µm SMF).
Q4: Is SFP-10G-LR compatible with various brands of equipment?
A: Yes. It is MSA-compliant and widely compatible with vendors like Cisco, Arista, Juniper, Huawei, FS.com, EdgeOptic, Axiom, and others.
Q5: Does SFP-10G-LR support hot-swapping?
A: Yes. It is designed to be hot-pluggable, allowing insertion/removal without powering off the host device.
Q6: Does it support Digital Diagnostic Monitoring (DDM/DOM)?
A: Yes. Most SFP-10G-LR modules include DDM/DOM (SFF-8472) support for monitoring parameters like optical power, temperature, voltage, and laser current.
Q7: What data rates are supported?
A: Supports 10 Gbps typical operation. Many models also support 1.25-10.31 Gbps multirate, enabling compatibility with lower-rate networks or protocols like OTU2 and Gigabit Ethernet.
Q8: What is typical power consumption?
A: Typically under 1.3 W, often around <1 W, depending on OEM/manufacturer.
Q9: What temperature ranges are supported?
A: Standard commercial modules cover 0C-70C. Industrial or extended variants may support -40C to 85C.
Q10: Which IEEE and MSA standards apply?
A: Compliant with IEEE 802.3ae (10GBASE-LR) and MSA SFF-8431/SFF-8472 (SFP+ electrical/diagnostic standards).
Q11: How to verify compatibility with my equipment?
A: Consult your network equipment documentation for support of generic 10G LR SFP+ optics, and verify the device allows third-party modules. Most OEM-compliant modules labeled SFP-10G-LR work across brands.
Q12: What applications are typical for SFP-10G-LR?
A: Widely used in data centre uplinks, interbuilding links, metro networks, campus backbone, and any single-mode fiber high-speed Ethernet links up to 10 km.
Q13: Are there variants offering extended reach or industrial specs?
A: Yes. Some versions support extended reach beyond 10 km, CPRI data rates, and industrial temperature ranges (e.g. SFP-10G-LR-X, SFP-10G-LR10-I).
Q14: What is the typical MTBF or reliability spec?
A: Vendor data (e.g. StarTech) indicates MTBF around 2,100,000+ hours (~240 years per unit), emphasizing reliability.
