What does 10GBase-SR mean, and how is it different from 10GBase-LR?

10GBase-SR is optimised for short to medium distances (up to 300 metres) using multi-mode fibre at 850 nm; it is more cost-effective than LR for campus and intra-building links.

What is the maximum distance this transceiver supports?

The TXM431-SR delivers 10 Gbps connectivity up to 300 metres over standard campus multi-mode fibre.

Which wavelength does this transceiver use?

This transceiver operates at 850 nm, a common wavelength for multi-mode fibre systems.

Can this transceiver connect to existing multi-mode fibre runs in our building?

Yes, if your building infrastructure uses standard multi-mode fibre (typically 50/125 µm or 62.5/125 µm), this transceiver integrates seamlessly.

Is full-duplex performance maintained with this transceiver?

Yes, the TXM431-SR supports full-duplex operation, enabling simultaneous two-way 10 Gbps communication.

What cable distances are typical for this transceiver in a large campus?

At 300 metres, this transceiver is suitable for building-to-building links or campus backbone extensions; longer distances require the 10GBase-LR transceiver.

How quickly can I obtain this transceiver in the GCC?

Availability and lead times vary; contact Procure.ae for current stock status and delivery estimates.

Does Procure.ae help with SFP+ transceiver selection and installation?

Yes, Procure.ae can advise on transceiver selection and deployment requirements; reach out to discuss your specific network topology.

What is the TXM431-SR transceiver?

The TXM431-SR is a 10GBase-SR SFP+ transceiver delivering 10 Gigabit full-duplex performance over multi-mode fibre at 850 nm.

What fibre types are compatible?

This transceiver is designed for standard campus multi-mode fibre, typically 50/125 µm or 62.5/125 µm core sizes.

Are universal SFP+ compatibility specs met?

Yes, this transceiver maintains full SFP+ compatibility across industry-standard equipment.

FAQ

Why choose SR over LR if I need shorter distances?
SR is more cost-effective for local links (up to 300 m), supports legacy multi-mode fibre infrastructure, and consumes less power than LR modules.

Can I upgrade my existing fibre runs to 10G with this transceiver?
Yes, if your campus fibre is multi-mode (OM2 or OM3), you can install SR modules without rewiring; verify fibre specification with your infrastructure team first.
