TP-LINK compatible TL-SM221B SFP Module

TP-LINK compatible TL-SM221B is SFP (Small Form factor Pluggable) Transceiver, operating over Single Fiber Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 17 dB, with in most cases is enough to reach about 15 km distance. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. This transceiver use top quality FP Laser transmitter with operating at nominal wavelength 1310 nm. and 1550 nm. PIN Photodiode receiver. It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. TP-LINK compatible TL-SM221B operates in Standard 0°-70°C temperature range and has Single LC interface. SFP support 100-155Mbps data rate and such applications as 100M Ethernet (100Mbps)|STM-1 (155Mbps). SFP Single Fiber optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Enterprice network Fast Ethernet Links, ISP FTTH Networking Fast ethernet Links, SONET/SDH STM-1 Links and other optical links.

Transceiver is CE/RoHS certified and it is Compliant with product safety standards. We perform compatibility tests for TP-LINK compatible TL-SM221B SFP Transceiver with latest platforms of TP-LINK networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with TP-LINK platforms. However, our optical transceivers are compliant to SFP Multi Source Agreement INF-8074i industry standard as well. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP transceiver EEPROM memory data validation tests.
