Pair the 1310 nm Transmit and 1550 nm Receive Direction of Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 with the Correct Type B Module at the Far End

Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 is a Type A bi-directional Fast Ethernet SFP for multimode fiber. It carries transmit and receive signals on different wavelengths through one fiber and therefore requires the complementary Type B endpoint.

A and B form a wavelength pair

Install Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 opposite a compatible Type B module that transmits at 1550 nm and receives at 1310 nm. Two Type A modules will not create the intended bidirectional wavelength pairing.

Label both ends of the Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 circuit with the A/B roles and fiber route. This is especially important where a technician can see only a single LC fiber at each endpoint.

Check multimode grade and loss

The manufacturer lists a 0-2 km range for Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 on the stated 50/125 um or 62.5/125 um conditions. Calculate the full route against the 16 dB budget, including every connector and splice.

Diagnostics for Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 include optical input/output power and module temperature. Use host-reported values to confirm the commissioned link and retain the results for maintenance comparison.

Order the exact A-side item

Specify Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 as part number 942204001 with the far-end Type B requirement. Do not accept the BB item on both ends merely because its distance and connector look similar.

The extended-temperature rating of Hirschmann SFP-FAST-BA MM/LC EEC Part Number 942204001 supports industrial locations, while host-switch approval remains separate. Confirm SFP compatibility and environmental scope for the complete link.
