The FluxLight MA-SFP-1GB-LX10-FL is a Meraki MA-SFP-1GB-LX10 compatible 1000BASE-LX SFP transceiver for Gigabit Ethernet over single-mode fiber up to 10 km. It transmits at 1310 nm, uses a duplex LC connector and supports digital diagnostics (DOM).
The MA-SFP-1GB-LX10-FL is coded for Meraki and works in the Meraki ports that take the MA-SFP-1GB-LX10, including Meraki MS125, Meraki MS130, Meraki MS150 and Meraki MX Security Appliances. Platform Support lists every supported model across 14 platform families.
It meets IEEE 802.3 1000BASE-LX, so it links to any 1000BASE-LX optic at the far end, whatever its brand. It follows the SFP MSA (SFF-8074i) and reports temperature, supply voltage, laser bias and optical power through SFF-8472 diagnostics. It uses an FP laser and a PIN receiver, draws under 1.0 W and is rated for a case temperature of 0 to 70 °C (commercial grade).
FluxLight guarantees it is compatible with Meraki and covers it with a 10-year warranty. The TAA-compliant version is MA-SFP-1GB-LX10-FLT.
The operation in excess of any absolute maximum ratings might cause permanent damage to this module.

The FluxLight transceivers have delivered and have worked even in my finicky switches.
Many optic in, and still no complaints or problems. So, yeah, good product.
Have installed over 100 of these. Not a single problem yet
Highest praise I can give - It's cheap and works with now fuss. Will be using them again.
Great products, fast shipping
