Applications
Network architects choose the 1G SFP GLC-EZX-SM-120 120km 1550nm Duplex LC/UPC Module, Cisco for enterprise access, campus, telecom edge and industrial network environments: it runs 1.25Gbps over SMF and reaches 120km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of GLC-EZX-SM-120.
Standards and Compatibility
Compliance: SFF-8472 MSA Compliant, IEEE 802.3ah-2004. For projects standardized on Cisco hardware, this product replaces the GLC-EZX-SM-120 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
Order this product as SFP1G-ZX120-55. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
