MikroTik compatible S-C59DLC40D Description

S-C59DLC40D is MikroTik Compatible SFP (Small Form factor Pluggable) Transceiver, operating over Double Fiber CWDM Single-Mode Fiber (SMF) optical cable. S-C59DLC40D has a minimum guaranteed optical budget of 19 dB, with in most cases is enough to reach about 40 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 MikroTik compatible transceiver use top quality DFB Laser transmitter with operating at nominal wavelength 1590 nm and 1270-1610 nm PIN Photodiode receiver. It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. MikroTik compatible S-C59DLC40D operates in Standard 0°-70°C temperature range and has Double LC interface. This compatible SFP support 1.063-1.25Gbps data rate and such applications as Gigabit Ethernet (1.25 Gbps). S-C59DLC40D 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 Internet Service Provider (ISP) Gigabit Ethernet communication links, Enterprice LAN & SAN Networks, Data Center LAN & SAN Networks and other optical links.

MikroTik compatible S-C59DLC40D transceiver is CE/RoHS certified and it is Compliant with product safety standards. MikroTik S-C59DLC40D 1.25G SFP Transceiver is fully compliant to SFP Multi Source Agreement INF-8074i. Consequently, it means that module is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules. However – we can provide SFP transceiver with custom-encoded firmware in order to make it work almost in any equipment. Therefore, we will be glad to know what your requirement is. 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 - Contact us!
