Finisar compatible FWLF1621P2Txx Description

Finisar compatible FWLF1621P2Txx is SFP (Small Form factor Pluggable) Transceiver, operating over Double Fiber CWDM Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 28 dB, with in most cases is enough to reach about 80 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 DFB Laser transmitter with operating at 1470-1610 nm nominal wavelength (when ordering specific Tx wavelength needs to be selected above) and a 1270-1610 nm PIN Photodiode receiver. It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. Finisar compatible FWLF1621P2Txx Transceiver operates in Industrial -40°C to 85°C temperature range and has Double LC interface. SFP support 100-2.67Gbps data rate and such applications as STM-16 (2.488 Gbps)|STM-4 (622Mbps)|STM-1 (155Mbps)|100M Ethernet (100Mbps)|Gigabit Ethernet (1.25 Gbps)|1G Fiber Channel (1.0625 Gbps)|2G Fiber Channel (2.125 Gbps)|OTU1 (2.66Gbps)|ODU0 (1.244Gbps)|ODU1 (2.498Gbps)|CPRI option 3 (2.458 Gbps)|CPRI option 2 (1228.8 Mbps). SFP Double Fiber CWDM optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are SDH/SONET Links of Backbone, LTE 4G RRU and BBU Interconnections in C-RAN Frounthaul, Different Ethernet and Fiber Channel SAN Links in Enterprise Networks and other optical links.

Finisar compatible FWLF1621P2Txx Transceiver is CE/RoHS certified and it is Compliant with product safety standards. Finisar is one of leading OEM manufacturer in our industry and their products are used by many equipment manufacturers. Our product EEPROM memory will be coded with necessary information to fully meet Finisar compatibility and will work seamlessly with platforms which support Finisar products . 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. If you have any questions, please Contact us. We will gladly learn about your needs and recommend the best compatible products from our portfolio.
