IBM compatible BN-CKM-QS-SR Description

IBM compatible BN-CKM-QS-SR is QSFP (Quad Small Form-factor Pluggable) Transceiver, operating over 4 Lanes of MMF optical cable. It has minimum guaranteed optical budget of 2.4 dB, with in most cases is enough to reach about 300 m 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 VSCEL Laser transmitter with operating at nominal wavelength 850 nm. and 850 nm. PIN photodiode receiver. It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. IBM compatible BN-CKM-QS-SR QSFP (Quad Small Form-factor Pluggable) operates in Standard 0°-70°C temperature range and has MTP/MPO interface. QSFP support 1.25-44.8 Gbps data rate and such applications as 4 x InfiniBand QDR(10Gbps)|40G Ethernet (41.25Gbps)|OTU3 (43.01Gbps)|OTU3e2 (44.58Gbps). IBM BN-CKM-QS-SR compatible QSFP 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) Fiber To The Home aggregation and backbone, Mobile operator core and backhaul 40G applications, Data Center networking site interconnections and other optical links.

Transceiver is CE/RoHS certified and it is Compliant with product safety standards. We perform compatibility tests for IBM compatible BN-CKM-QS-SR QSFP Transceiver with latest platforms of IBM networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with IBM platforms. However, our optical transceivers are compliant to QSFP MSA 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 transceiver EEPROM memory data validation tests.
