Cisco compatible GLC-LH-SMD Description
EdgeOptic's GLC-LH-SMD compatible is a Cisco-coded version of the EdgeOptic 1.25G-SFP-10D multi-vendor single-mode Gigabit Ethernet SFP transceiver. It uses a 1310 nm FP laser transmitter and PIN photodiode receiver over a duplex LC/UPC connector, single-mode fiber only. Reach is 10 km with a 13 dB average link budget. TX output ranges from -9 to 3 dBm, RX sensitivity is -22 dBm and RX overload is -3 dBm.
Supported line rate spans 1.063 to 1.25 Gbps, covering Gigabit Ethernet (1.25 Gbps) and 1G Fibre Channel (1.0625 Gbps) applications on compatible Cisco host ports. The 1310 nm transmitter operates across a 100 nm band (1260 to 1360 nm), with chromatic dispersion between 70 and 100 ps/nm across the fiber link. This SFP is built for single-mode fiber only; it does not support multimode fiber or mode-conditioning patch cords. Digital optical monitoring (DOM) reports live transceiver operating parameters through the standard SFP diagnostic interface.
The module ships with Cisco-coded EEPROM identification for compatible Cisco switches and routers. Verify the specific model and software release against Cisco's own compatibility and ordering guide for the target platform before deployment.
Operating temperature is rated 0 to 70 degrees Celsius. The module meets CE and RoHS requirements, Class 1 laser safety under FDA and IEC 60825-1, and the INF-8074i SFP MSA mechanical and electrical interface.
EdgeOptic backs the GLC-LH-SMD compatible with a lifetime warranty and compatibility engineering across vendor optical platforms. For volume pricing or an alternative vendor coding, contact our sales team.
Frequently Asked Questions
Does GLC-LH-SMD add DOM monitoring that GLC-LH-SM lacks?
Yes. GLC-LH-SMD adds digital optical monitoring (DOM), reporting live transceiver operating parameters through the SFP's standard diagnostic interface. The base GLC-LH-SM part number does not include this monitoring capability. EdgeOptic's GLC-LH-SMD compatible carries DOM support as standard, matching the root 1.25G-SFP-10D specification.
