Cisco GLC-LH-SM 30-1299-03 CN8ID42AAC 1000BASE-LX/LH SFP Transceiver Module

Cisco's industry-standard SFP is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of IEEE 802.3z- compliant 1000BaseSX, 1000BaseLX/LH, or 1000BaseZX interfaces on a port-by-port basis.

The Cisco GLC-LH-SM fully complies with the IEEE 802.3z 1000BaseLX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard.

Solid SFP for older switch uplink Used this for a 1Gb fiber uplink between two older Cisco switches. Setup was basically plug in the SFP, patch the LC fiber, done. First use was uneventful which is what you want. Build quality feels like a genuine Cisco module, not flimsy. I’ve had it in daily use for about a month and the connection has stayed stable with no drops so far. 5

Works right away on Cisco gear Popped this into a Cisco switch and it came up right away. No weird errors, link established fast over single-mode fiber. Been running for a couple weeks now and temps seem normal. 5
