Cisco compatible SFP-1G-LH Description
EdgeOptic's SFP-1G-LH compatible is a Cisco-coded version of the EdgeOptic 1.25G-SFP-10D multi-vendor 1000BASE-LX SFP transceiver. It covers 10km of single-mode fiber at 1310nm over a duplex LC interface, with a 13 dB average link budget and DDM/DOM diagnostics for TX and RX power monitoring.
Cisco's own Gigabit Ethernet SFP datasheet documents the SFP-1G-LH operating in 10G, 10/25G dual-rate, and 10/25/50G tri-rate SFP+ ports while delivering 1G connectivity over the media side. That host interface differs from Cisco's GLC-LH-SM and GLC-LH-SMD parts, built for legacy fixed-1G SFP ports. Confirm the target Cisco switch or router port belongs to the SFP-1G multi-rate family before ordering, rather than assuming it drops into any 1G SFP slot.
The module supports Gigabit Ethernet (1.25 Gbps), 100M Ethernet, and 1G Fibre Channel (1.0625 Gbps) traffic, with transmit power from -9 to 3 dBm and receiver sensitivity of -22 dBm. An FP laser transmitter pairs with a PIN photodiode receiver across a 0 to 70°C commercial operating range at 3.3V. The design follows the INF-8074i SFP interface specification and SFP MSA, with CE marking and Class 1 laser safety per FDA and IEC 60825-1.

Frequently Asked Questions
Is the Cisco SFP-1G-LH interchangeable with the GLC-LH-SMD?
No. The SFP-1G-LH is built for Cisco's 10G, 10/25G dual-rate, and 10/25/50G tri-rate SFP+ ports and delivers 1G connectivity over those multi-rate cages. The GLC-LH-SM and GLC-LH-SMD modules target Cisco's legacy fixed-1G SFP ports. Match the part number to the port type the target Cisco platform documents rather than treating these as interchangeable 1000BASE-LX options.
Does the SFP-1G-LH work in any Cisco 1G SFP port?
Not automatically. Cisco documents the SFP-1G-LH operating in 10G, 10/25G dual-rate, and 10/25/50G tri-rate SFP+ ports rather than in native 1G-only SFP cages. Check the Cisco switch or router port specification for SFP-1G family support before ordering, and use the GLC-LH-SM or GLC-LH-SMD part number if the port is a fixed 1G SFP slot.
