SFP transceiver module BlueOptics 490NAC0201-BO 1250 Mbit/s

The BlueOptics 490NAC0201-BO SFP transceiver module is a compact fiber-optic interface designed for use in network equipment that supports SFP ports. It supports a maximum data transfer rate of 1250 Mbit/s and is compatible with single-mode fiber links up to 10,000 m. The module comes in a silver housing and uses an LC fiber connector, offering a standard 1.25 Gigabit Ethernet interface for media conversion and uplink applications. With an MTBF of 1,000,000 hours, the transceiver is intended for continuous operation in access, distribution and backbone network segments.

Advantages

Small SFP form factor enables dense port deployment and straightforward hot-plug replacement without powering down equipment. Support for 1250 Mbit/s throughput and a single-mode LC connector provides compatibility with common legacy and current fiber networks. The module's silver housing and lightweight design simplify handling and installation while the specified MTBF indicates long operational life under normal conditions.

Suitable for

• Fiber uplinks between switches and routers in enterprise and carrier networks
• Media conversion appliances requiring SFP 1.25G modules
• Long-reach single-mode links such as campus backbone segments up to 10 km
• Network equipment vendors and system integrators needing standardized LC SFP transceivers

Key specifications

• Maximum data transfer rate: 1250 Mbit/s
• Maximum transfer distance: 10000 m (single-mode fiber)
• Ethernet interface type: 1.25 Gigabit Ethernet
• Fiber optic connector: LC
• Product colour: Silver
• Weight: 0.02 kg
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Insert the SFP transceiver into an available SFP slot on a compatible switch, router or media converter until it seats firmly and the latch engages. Connect an LC-terminated single-mode fiber patch cable to the module's LC connector, observing correct transmit/receive alignment. Ensure the network device is configured for the intended link speed and duplex settings; most devices will auto-negotiate with a 1.25G SFP module. Monitor link status on the host device to confirm the optical connection and verify traffic flow through the interface.

Recommendations

Handle the transceiver by its body and avoid touching the fiber connector endface. Keep dust caps on when the module is not connected, and use proper ESD precautions during installation. For reliable long-term operation, install the module in equipment with adequate ventilation and operate within the manufacturer's specified environmental limits. Verify fiber type and attenuation budgets for links approaching the 10,000 m maximum distance.
