Usage Guidelines & Best Practices

1. Complementary Pairing Requirement Bidirectional transceivers must be deployed in matched wavelength pairs. This TX1550/RX1310 BiDi SFP Module requires a counterparty TX1310/RX1550 transceiver at the opposite fiber end; mismatched wavelength pairs cannot establish valid fiber links.
2. Fiber Type Restriction Only use standard 9/125μm single mode fiber (SMF) with LC/UPC patch cords. This transceiver cannot operate normally on multi-mode fiber (MMF), which triggers severe attenuation and persistent random bit errors.
3. Power Range & Short-Distance Testing This module operates with a transmit power (TX) of -14 to -8 dBm and a receiver overload threshold of -8 dBm. Since the maximum TX power does not exceed the overload limit, external optical attenuators are generally not required for short-distance connections or bench testing. However, always ensure that the received optical power (RX Power) remains strictly at or below -8 dBm to prevent receiver saturation.
4. Optical Port Dust Protection LC optical ports and fiber end faces are highly sensitive to dust and fingerprint contamination. Always reinstall protective dust caps on idle module ports and unused fiber connectors after disconnection.
5. Hot-Plugging Operation Guidance This MSA-compliant BiDi SFP Transceiver supports safe hot swap. Leave several seconds between removal and reinsertion to let Cisco IOS complete full hardware recognition and avoid unexpected link flapping.
