# Product Documentation
Multi-Vendor MSA Compatible BIDI-1.25G-SFP-20-AD SFP Datasheet

D-link Compatible DEM-220R SFP Module is based on our product BIDI-1.25G-SFP-20-AD. When You will order it will be encoded to be compatible with D-link equipment and it will be labeled with part number: BIDI-1.25G-SFP-20-AD-DK, where DK means D-link Compatible. Above You can download datasheet of our BIDI-1.25G-SFP-20-AD product.

# Product Description

Our Compatible D-link DEM-220R SFP transceiver is based on our BIDI-1.25G-SFP-20-AD product, which has the same parameters and is manufactured in accordance with the same industry standards as its OEM counterpart. Our compatible module version is designed for operation over a Single Fiber Single-Mode Fiber (SMF) optical cable. It has a minimum guaranteed optical budget of 14 dB, which typically is enough to reach about 20 km. However, distance is only an indicative parameter calculated for identification comfort. Finally, we calculate distance while keeping in mind the minimum (guaranteed) optical budget and the average attenuation of optical cabling in the industry. Our D-link DEM-220R compatible transceiver uses a high-quality FP Laser transmitter operating at 1310 nm nominal wavelength and a 1550 nm PIN Photodiode receiver. This module supports DDM/DOM optical diagnostics and provides diagnostic data about the current operating conditions. This compatible module has a Single LC connector and module is designed for operation in standard temperature networking environments ranging from 0°-70°C. The transceiver chipset supports data rates ranging from 1.063-1.25Gbps and such applications as Gigabit Ethernet (1.25 Gbps), 1G Fiber Channel (1.0625 Gbps). It is important to note that the mentioned application support will vary depending on the port where the module will be used, and it supported applications as well as module speed configuration during ordering process, but we can ensure that our module will support at least the same functionality as its OEM counterpart. This is a multi-purpose transceiver that can be used in a variety of different places in today’s networking. As a result, Internet Service Provider (ISP) Gigabit Ethernet communication links, Enterprise LAN Networks, Data Center LAN Networks, and other optical links are the most popular applications for this product.

Our compatible D-link DEM-220R module is CE/RoHS certified, it meets product safety standards, and is compliant with SFP Multi Source Agreement (MSA) SFF-8477 industry standard. To ensure smooth operation, we have completed compatibility tests for this module with the most recent platforms of D-link networking equipment, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly in D-link platforms. We are committed to quality, therefore before delivering our products, we conduct stringent quality inspections that include optical parameter measurements, connector cleanliness tests, and EEPROM memory data validation tests.
