Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco SFP-50G copper cables

Cisco SFP56 to SFP56 copper direct-attach 25/50GBASE-CR1 cables are suitable for very short links and offer a highly cost-effective way to establish a 25 and 50 Gigabit link between SFP56 ports found switches, routers, or other platforms within a rack and across adjacent racks. Cisco offers passive copper cables in lengths of 0.5, 1, 1.5, 2, 2.5, 3, 4, and 5 meters.

For 50G mode, all cable lengths require RS-FEC (544,514) also known as KP1-FEC on host ports.

For 25G mode, the 0.5, 1, 1.5, and 2m cables do not require FEC on the host ports; 2.5 and 3m cables require BASE-R FEC (also known as FC-FEC) on the host ports; 4 and 5m cables require RS-FEC (528,514) also known as KR1-FEC on the host ports.

The SFP-50G copper cables feature an LSZH (Low Smoke Zero Halogen) jacket.

Cisco SFP-50G-SL

Cisco SFP-50G-SL Short Link Modules are a replacement for traditional AOCs (Active Optical Cables). They are suitable for very short distances and offer a cost-effective way to connect within a rack and across adjacent racks at up to 30 meters.

For 50G operation, the module requires KP1-FEC on the host port for link lengths of 20/30/30 m on OM3/4/5 MMF.

For 25G operation, the module supports:

      20/30/30 m on OM3/4/5 with KR1-FEC,

      10/16/16 m on OM3/4/5 with FC-FEC, and

      7/10/10 m on OM3/4/5 with No-FEC.

Cisco SFP-50G-SR-S

For 50G mode, the Cisco 50GBASE-SR-S module supports a link length of 70/100/100 m on OM3/4/5 MMF with KP1-FEC on the host port.

For 25G mode, the Cisco 50GBASE-SR-S module supports a link length of:

      70/100/100 m on OM3/4/5 MMF with KR1-FEC,

      10/16/16 m on OM3/4/5 MMF with FC-FEC, and

      7/10/10 m on OM3/4/5 MMF with No-FEC.

Cisco SFP-50G-LR-S

The Cisco SFP-50G-LR-S Module supports a link length of 10/15 km on standard Single-Mode Fiber (SMF) G.652 at both 25G and 50G.

For 50G mode, the module requires KP1-FEC on the host ports, and for 25G mode, the module requires
KR1-FEC on the host ports.
