The STC-80043 is a long-range 10G SFP+ BiDi transceiver designed for single-fiber 10 Gigabit Ethernet transmission up to 60 kilometers. Using 1270nm TX and 1330nm RX wavelengths over single-mode fiber (SMF), this compact module delivers high-speed connectivity with minimal fiber. Complete technical specifications and product details PLANET compatible MTB-LA60 is SFP+ (Small Form factor Pluggable) Transceiver, operating over Single Fiber Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 21 dB, with in most cases is enough to reach about 60 km. The BI-DI SFP+ 60KM module electrical interface is compliant to SFI electrical specifications. The transmitter input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled. The module provides differential termination and reduce differential to common mode. o In optical modules, "core" refers to the light-transmitting channel in the fiber. This 10G BiDi SFP+ transceiver, featured with data transmission over a single strand of fiber, the one transceiver transmits a 1330-nm channel and receives a 1270-nm signal, whereas the other BiDi SFP+. It is a transceiver module designed for 60km optical communication applications. The design is compliant to 40GBASE-ZR4 Lite of the IEEE P802.
