The CB-10E-20-CD2302 and CB-10E-20-CD3202 are single-fiber bidirectional SFP+ transceiver solutions designed for 10 Gigabit Ethernet (10GbE) and 10G Fiber Channel applications. They operate over single-mode fiber using complementary wavelength pairs, one variant transmitting at 1270nm and receiving at 1330nm, and the other transmitting at 1330nm and receiving at 1270nm, enabling full-duplex data transmission on a single optical fiber. Both modules support data rates up to 10.7Gbps and transmission distances up to 20km. They comply with the SFP+ MSA and the SFF-8472 Digital Diagnostics Monitoring (DDM) standard.
