SFP Fast Ethernet Transceiver Dual LC MMF
The SFP Fast Ethernet Transceiver Dual LC Multi-Mode Fibre (Telsey
Code MAFB1LMM10T--) is a hot pluggable 3.3V Small-Form-Factor
(SFP) transceiver module, expressly designed for high-speed
communication applications that require rates of up to 155Mbit/sec.
It is compliant with the Fast Ethernet, SONET OC-3, SDH STM-1 L-1
standards, as well as the SFP Multisource Agreement (MSA).
The MAFB1LMM10T-- transceiver is equipped with a dual LC
connector. The transceiver is also compatible with industry standard
RFT connector and cage. It also includes a LOS (Loss Of Signal) circuit
that provides a TTL logic-high output when an unusable optical signal
level is detected.
The MAFB1LMM10T-- transceiver is a Class1 eye safety product. The
optical power levels, under normal operation, are at eye safe level.
