SFP+ SR Transceiver

The SFP+ SR transceiver is the fully specified 10G line in this catalogue. Its published specification sheet states a 10G rate, an 850nm wavelength, a 300m reach over multimode fiber with an LC connector, and a multimode fiber bandwidth rating of 2000MHz/km. The published model is BT-SFP+-SR. The standards named on the product page are IEEE 802.3ae 10GBASE-SR and SFF-8431, and the stated applications include 8.5G and 10G Fibre Channel and 10GB Ethernet. Those figures belong to this product alone and are not shared with any other transceiver on this site.

Ten gigabit over multimode fiber is the workhorse connection of the modern data centre and enterprise network. It is the speed at which most server connections, storage links and aggregation uplinks have run for years, and it remains the right choice wherever the installed fiber is multimode and the link is within a building. The 850nm wavelength is the short-wavelength window used for multimode transmission, and the 300m reach covers the great majority of in-building links, from top-of-rack switching to end-of-row aggregation and between floors.

The 2000MHz/km fiber bandwidth rating is worth understanding, because it is the figure that ties the module to the fiber grade. Multimode fiber comes in grades, and the reach a module achieves depends on the grade it runs over. The published 300m figure is stated against a 2000MHz/km fiber, and a buyer running over a lower-grade plant should confirm the expected reach during the inquiry rather than assume the full 300m. Conversely, a buyer whose plant meets that grade can plan on the published figure. The inquiry form is the right place to state the fiber grade and the actual link length, so the answer can be specific rather than general.

The LC connector is the standard duplex connector for SFP+ modules, and it is what makes this module a drop-in replacement in the great majority of 10G installations. A buyer replacing an existing 10G module, or populating a new switch, can generally assume LC duplex patch cords and panels, which keeps the migration simple. The Fibre Channel application note matters for storage buyers: the same module family serves both Ethernet and Fibre Channel links at 8.5G and 10G, which simplifies spares holdings for sites that run both.

The operating temperature range of 0 to 70 degrees Celsius covers ordinary indoor installations. A buyer planning an installation in a warmer or unconditioned space should raise it during the inquiry. Power consumption is not published as a separate figure for this model on the product page, and this site does not borrow a figure from a neighbouring model, so a buyer who needs it for a thermal budget should ask for it during the inquiry.

On certification, the product page for this model states RoHS compliant. That statement is reported here as a product-page statement, not as a certificate reproduced on this site. Certificates are available upon request. No prices, minimum order quantities, delivery times or stock figures are stated for this model, because none have been published. Before ordering, confirm quantity, price and delivery time during the inquiry, together with the fiber grade and link length your installation uses.
