SFP-7421 version: 3 155m single-mode bidi sfp transceiver (40km, tx/rx over 1310/1550nm) the levelone SFP-7421 is a high performance, cost-effective sfp transceiver. it provides up to 155mbps bi-directional data transfer rate at distances up to 40km on a single fiber core. these bi-directional sfp transceivers allow data transfer in either direction through a single optical fiber by employing separate wavelengths travelling in either direction. the SFP-7421 transmits using a wavelength of 1310nm and receives using a wavelength of 1550nm. when coupled with the levelone sfp-7431 transceiver which transmits at and receives at the opposite rates (1310nm tx and 1550nm rx) you get bi-direction data communication on a single fiber core. key features - 1310nm fp ld - data rate: 125~155mbps, nrz - single +3.3v power supply - rohs compliant and lead-free - ac/ac differential electrical interface - compliant with multi-source agreement(msa) - compliant with sff-8472 digital diagnostic monitoring interface - single lc connector - compliance with specifications for ieee802.3ah 100base-bx10-u - compliance with fddi pmd standard - compliance with atm standard www.level1.com page 1 of 4
