Frequently Asked Questions - SFP-BXU ComNet
What is the SFP-BXU transceiver used for?
The SFP-BXU is a bidirectional (BiDi) SFP module designed for uplink connections in Gigabit Ethernet networks. It transmits at 1310 nm and receives at 1550 nm, allowing full-duplex communication over a single strand of single-mode fiber.
How far can the SFP-BXU transmit data?
The SFP-BXU supports distances of up to 10 kilometers over standard single-mode fiber (9/125 µm) at a data rate of 1.25 Gbps.
Is the SFP-BXU compatible with other brands of switches?
The SFP-BXU follows the Multi-Source Agreement (MSA) standard and is generally compatible with any Gigabit Ethernet switch or router that has an SFP port. However, for guaranteed performance, it is recommended to use it with ComNet equipment or check your device's compatibility list.
What is the difference between SFP-BXU and SFP-BXD?
The SFP-BXU and SFP-BXD are paired modules for single-fiber BiDi communication. The BXU (uplink) transmits at 1310 nm and receives at 1550 nm, while the BXD (downlink) transmits at 1550 nm and receives at 1310 nm. They must be used in pairs at opposite ends of the fiber.
Can the SFP-BXU be hot-swapped?
Yes, the SFP-BXU is hot-pluggable, meaning it can be inserted or removed while the switch or router is powered on without causing damage or interrupting other modules.
What type of fiber optic cable is required?
Use a single-mode fiber (9/125 µm) with a simplex LC connector. Since the SFP-BXU uses BiDi technology, only one fiber strand is needed for both transmit and receive.
How do I clean the optical connectors on the SFP-BXU?
Clean the LC connector with a lint-free cleaning swab and isopropyl alcohol or a dedicated fiber cleaner. Gently wipe the ferrule end-face and allow it to dry before insertion. Always keep dust caps on when not in use.
Does the SFP-BXU support Digital Diagnostic Monitoring (DDM)?
Yes, the SFP-BXU includes DDM (also called DMI) features, allowing real-time monitoring of temperature, supply voltage, TX/RX power, and bias current via the host device's management interface.
What should I do if the link does not come up?
Check the following: ensure the SFP-BXU is paired with an SFP-BXD at the other end, verify the fiber is single-mode and properly connected, confirm the switch settings (auto-negotiation or forced 1000BASE-X), and inspect the optical connectors for dirt or damage. Use DDM to check received power levels.
Is the SFP-BXU repairable if it fails?
The SFP-BXU is a sealed module with no user-serviceable parts. If it fails, it must be replaced. Contact your supplier or ComNet for warranty replacement or to purchase a new module.
