1G SFP GLC-EZX-SM-120 120km 1550nm Duplex LC/UPC Module, Cisco

The 1G SFP GLC-EZX-SM-120 120km 1550nm Duplex LC/UPC Module, Cisco is a SFP optical transceiver delivering 1.25Gbps over SMF. Operating at 1550nm with a Duplex LC interface, it reaches 120km and is compliant with SFF-8472 MSA Compliant, IEEE 802.3ah-2004. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in enterprise access, campus, telecom edge and industrial network environments.

Product Highlights

• SFP form factor, 1.25Gbps data rate
• Wavelength: 1550nm
• Connector: Duplex LC
• Reach: up to 120km
• Fiber media: SMF
• Operating temperature: 0 to 70°C (32 to 158°F)

Built for enterprise access, campus, telecom edge and industrial network environments, this SFP module carries 1.25Gbps over SMF up to 120km per link. 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.

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.

Our part number for this module is SFP1G-ZX120-55. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

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.

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.

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.

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.
