Confirm the A-side partner
The remote endpoint for Hirschmann SFP-FAST-BB SM+/LC EEC Part Number 942206002 should use the approved Type A module that transmits at 1310 nm and receives at 1550 nm. Confirm both part numbers as a pair before shipment.
Mark the switch port containing Hirschmann SFP-FAST-BB SM+/LC EEC Part Number 942206002 as the Type B side. Wavelength-direction records are essential on a single-fiber route because the connector alone does not show which member belongs at each end.
Validate a 60 km optical design
Calculate route loss for Hirschmann SFP-FAST-BB SM+/LC EEC Part Number 942206002 at the relevant wavelengths, including fiber, connectors, splices and repair history. Compare the total with the published 29 dB budget and retain margin.
Use optical input/output power diagnostics from Hirschmann SFP-FAST-BB SM+/LC EEC Part Number 942206002 during commissioning when supported by the host. A measured baseline helps separate later fiber degradation from configuration or equipment changes.
Keep the long-reach B model exact
Specify Hirschmann SFP-FAST-BB SM+/LC EEC Part Number 942206002 with part number 942206002 and the matching Type A requirement. Do not substitute the 2 km multimode B version merely because both names contain BB.
