Cisco compatible SFP-25G-ER-S Description

Our Compatible Cisco 25G SFP Compatibility Matrix & Price is based on our product 25G-SFP28-40, which has the same specifications and is manufactured in accordance with the same industry standards. The 25G SFP Cisco compatible module is intended for use with Double Fiber Single-Mode Fiber (SMF) optical cable. It has a minimum guaranteed optical budget of 16 dB, which is usually enough to reach up to 40 km distance as per Cisco 25G SFP Datasheet specification. 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 compatible Cisco 25G SFP Compatibility Matrix module version uses a high-quality EML Laser transmitter with operating at nominal wavelength 1310 nm. and 1310 nm. APD 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 Cisco 25G SFP Datasheet compatible module has a Double LC interface and operates in the Standard 0°-70°C temperature range. This SFP+ module supports data rates ranging from 8.5-28.1 Gbps data rate and such applications as 25G Ethernet (25.78Gbps), 10G Ethernet (10.31Gbps). Our 25G SFP Cisco 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 Cisco 25G SFP Datasheet compatible interfaces, Mobile Operator Core and Backhaul applications, Data Center networking for Ethernet connections and other optical fiber links. Our 25G SFP Cisco compatible transceiver has proven to be reliable in temperature-controlled server rooms over a long period of time. 25G SFP 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 25G SFP Compatibility Matrix and Price are based on our product 25G-SFP28-40, which is CE/RoHS certified and fulfills product safety standards. We perform compatibility tests for Cisco 25G SFP Datasheet compatible 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 SFF-8431, SFP+, MSA, SFF-8402, SFF-8472, SFF-8432, IEEE 802.3cc, CE, RoHS-6, Class 1 FDA and IEC60825-1. 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.
