# Product Description

    Our Compatible Cisco 1G SFP compatibility matrix supported transceiver is based on our product 1.25G-SFP-10D, which has the same specifications and is manufactured in accordance with the same industry standards. The Cisco compatible GLC-GE-DR-LX SFP module is intended for use with Double Fiber Single-Mode Fiber (MMF) optical cable. It has a minimum guaranteed optical budget of 13 dB, which is usually enough to reach up to 10 km distance as per Cisco GLC-GE-DR-LX specifications. However, distance is only an indicative parameter calculated for identification comfort. Finally, we calculate distance while keeping in mind the minimum optical budget and the average attenuation of optical cabling in industry. Our Cisco 1G single mode fiber SFP compatible module version uses a high-quality FP Laser transmitter with a nominal wavelength of 1310 nm and a 1310 nm PIN Photodiode receiver. DDM/DOM optical diagnostics are supported by this module, which provides diagnostic information about the current operating conditions. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The compatible Cisco GLC-GE-DR-LX module has a Double LC interface and operates in the Standard 0°-70°C temperature range. This SFP+ module supports data rates ranging from 1.063 to 1.25 Gbps and applications such as Gigabit Ethernet (1.25 Gbps). Our Cisco GLC-GE-DR-LX module is a multi-purpose module that can be used in a variety of networking applications. Consequently, most popular applications are Internet Service Provider, Fiber to The Home routing and switching equipment with GLC-GE-DR-LX SFP compatible interfaces, Mobile Operator Core and Backhaul applications, Data Center networking for Ethernet connections and other optical fiber links. Our compatible Cisco SFP 1G LX transceiver has proven to be reliable in temperature-controlled server rooms over a long period of time SFP 1G LX Cisco compatible transceivers do not require any maintenance while in use. The only possible maintenance requirement could occur during cable replacement, when the transceiver connector must be thoroughly cleaned of dust using special optical connector cleaning tools. Therefore ensuring the best connection possible – leading to best performance!
Our Compatible Cisco 1G SFP compatibility matrix supported transceiver is based on our product 1.25G-SFP-10D, which is CE/RoHS certified and fulfills product safety standards. We perform compatibility tests for Cisco compatible GLC-GE-DR-LX SFP+ Module with the most recent Cisco networking equipment platforms, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly with Cisco platforms. Furthermore, our optical transceivers comply with the SFP+ Multi Source Agreement industry standard and is intended to work with any major Cisco platform which supports GLC-GE-DR-LX compatibility. Because we are committed to providing high-quality service, we conduct rigorous quality checks before delivering our products. As a result, we perform optical parameter measurements, connector cleanness tests, and EEPROM memory data validation tests on SFP+ transceivers.
