Extreme compatible 10GB-BX10-U Description

EdgeOptic's 10GB-BX10-U compatible is an Extreme-coded Tx1270/Rx1330 version of the EdgeOptic BIDI-10G-SFP-20A multi-vendor 10G BiDi SFP+ transceiver. It carries Extreme-recognized identification data, so ExtremeXOS and ExtremeSwitching platforms with 10G SFP+ ports read it as a matching module. The U designation marks the upstream A-side of a bidirectional pair, transmitting at 1270 nm and receiving at 1330 nm over a single strand of single-mode fiber.

Extreme rates the original 10GB-BX10-U for up to 10 km. The EdgeOptic compatible is built on the BIDI-10G-SFP-20A platform with a 9 dB link budget rated for spans up to 20 km, which makes it a direct drop-in replacement for any 10 km Extreme deployment. The extra link budget covers splice loss, connector loss, and fiber aging across the lifetime of the span. RX overload of +4 dBm sits above the 0 dBm maximum transmit power, so a short fiber run between two of these modules will not saturate the receiver.

The 10GB-BX10-U pairs at the remote end with a downstream B-side module that transmits at 1330 nm and receives at 1270 nm, such as the Extreme 10GB-BX10-D. The optical interface uses a DFB laser transmitter and a PIN photodiode receiver. Transmit power runs from −5 dBm to 0 dBm, receiver sensitivity is better than −14.5 dBm. The module uses a single LC/UPC connector, runs on a +3.3 V supply across a 0 to 70 C operating range, and supports digital optical monitoring per SFF-8472. Build compliance follows the SFP MSA and SFF-8431, with Class 1 laser rating per IEC 60825-1.

The module handles 10 Gigabit Ethernet and Gigabit Ethernet traffic across Extreme campus switches with 10G SFP+ ports. For deployment on a specific switch model, verify the part against the Extreme transceiver compatibility matrix for that chassis, or contact our sales team.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the 10GB-BX10-U compatible ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions

Will the EdgeOptic 10GB-BX10-U compatible work as a drop-in for the 10 km Extreme original?

Yes. The EdgeOptic compatible is built on the BIDI-10G-SFP-20A platform, which carries a 9 dB link budget rated for spans up to 20 km. Extreme rates the original 10GB-BX10-U for 10 km, so the EdgeOptic module covers that span and adds headroom for connector and splice loss. Receive overload tolerance of +4 dBm exceeds the 0 dBm maximum transmit power, so a short fiber run between two of these modules does not risk receiver saturation.

What module sits at the remote end of a 10GB-BX10-U link?

The U-side transmits at 1270 nm and receives at 1330 nm, so the remote end must run the opposite direction: transmit at 1330 nm, receive at 1270 nm. The matching Extreme part is the 10GB-BX10-D. Ordering two U-side modules for both ends of a link is the most common BiDi mistake; verify wavelength direction on both endpoints before commissioning.
