LANVIEW Cisco GLC-EZX-SM-120 kompatibilný 1000BASE-EZX SFP transceiver, 1Gbps Single-Mode LC Duplex, 120km, 1550nm, DDM, Hot-Swappable

For network engineers who need to bridge extreme distances over single-mode fibre without adding amplifiers or repeaters, the LANVIEW MO-GLC-EZX-SM-120 delivers a full 120-kilometre reach in a standard SFP form factor. This Cisco GLC-EZX-SM-120 compatible module pairs a 1550 nm DFB laser with a sensitive receiver to maintain a stable 1 Gbps link across long-haul backbones, campus interconnects, and service provider access networks. Unlike generic SFPs that push transmit power to the edge and ignore thermal drift, this unit keeps output between 0 and 5 dBm and supports digital diagnostics so you can monitor optical parameters live from the host switch.

Highlights

• 1000BASE-EZX interface for Gigabit Ethernet over single-mode fibre
• 120 km maximum transmission distance at 1550 nm wavelength
• LC duplex connector with hot-swappable SFP cage compatibility
• Digital Diagnostic Monitoring (DDM) for real-time optical health checks
• MSA and RoHS compliant, built for Cisco SFP-compatible ports
• Low power consumption under 1.0 W with 0–70 °C operating range

In daily use

The module fits any standard SFP port and negotiates at 1 Gbps without extra configuration. Its DFB transmitter and -28 dBm receiver sensitivity leave enough optical budget for splices, patch panels, and ageing fibre, so a 120 km link remains error-free even in less-than-perfect installations. DDM lets you read temperature, TX/RX power, and bias current through the switch CLI or NMS, turning a blind long-haul span into a monitored asset. Because the unit is hot-swappable, you can replace it in a live chassis without downtime, and the metal housing dissipates heat effectively across the full 0–70 °C operating window.
