Applications
The 1G SFP GLC-BX-20D 20km 1550nm-TX/1310nm-RX Simplex LC/UPC Module, Cisco is used in enterprise access, campus, telecom edge and industrial network environments, where it provides a 1.25Gbps link over SMF up to 20km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with Cisco platforms and replaces the Cisco part GLC-BX-20D directly.
Standards and Compatibility
Compliance: Fast Ethernet, Gigabit Fibre Channel, MSA Compliant. For projects standardized on Cisco hardware, this product replaces the GLC-BX-20D 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 SFP-1G53-BX20. 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.
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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
