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. The Duplex LC interface and 1550nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Cisco hardware, it is a drop-in equivalent of the 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
To order, quote SFP1G-ZX120-55 together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
