Cisco compatible DS-SFP-FC4G-SW Description
EdgeOptic's DS-SFP-FC4G-SW compatible is the 10GBASE-SR SFP+ upgrade alternative for the legacy Cisco DS-SFP-FC4G-SW 4GFC SW SFP module. The original DS-SFP-FC4G-SW is a regular SFP (not SFP+) 4 Gbps Fibre Channel Shortwave optic for the Cisco MDS 9000-series SAN switch family, governed by the INCITS 404-2006 FC-PI-2 standard for 4GFC. The DS- prefix designates the Cisco MDS Storage product family. The original 4GFC SFP was the standard SAN-fabric optic for 1/2/4 Gbps Fibre Channel deployments before the modern SFP+ transition to 8GFC, 10GFC, and 16GFC fabrics.
The EdgeOptic 10GBASE-SR replacement is an SFP+ form factor module built to IEEE 802.3ae Clause 52, with a 6.1 dB optical budget, 850 nm VCSEL transmitter, LC duplex interface, transmit power between −5 and 0 dBm, and receive sensitivity better than −11.1 dBm. The reach envelope is 300 m on OM3 and 400 m on OM4 multimode fiber. The SR module is the forward-compatible replacement for fabric switches that have migrated their host ports to SFP+ cages, typical of current-generation Cisco MDS directors that support SFP+ host ports on 8GFC and 16GFC line cards. Hosts still running SFP-only cages (legacy 4GFC SAN switches that were never refreshed to SFP+) cannot accept the SFP+ optic directly. Verify cage compatibility against the Cisco MDS line card documentation before substituting.
Cisco-recognized EEPROM coding identifies the module under the ordering code that the host expects, so the SFP+ registers cleanly on Cisco MDS platforms with SFP+ host ports. Digital diagnostics per SFF-8472 reports temperature, supply voltage, transmit bias current, transmit power, and receive power on every read. The EdgeOptic SR replacement runs to the Ethernet 10GBASE-SR specification. The 4GFC Fibre Channel protocol on the original DS-SFP-FC4G-SW is governed by FC-PI-2 with its own signaling rate of 4.25 Gbps and its own reach budget; the SR replacement is an Ethernet optic and is not a like-for-like protocol substitute on the same SAN fabric. The SR module is the cage-compatible Ethernet alternative for fabric switches that have been refreshed for SFP+ host port use.

Frequently Asked Questions
Does replacing a DS-SFP-FC4G-SW with a 10GBASE-SR SFP+ require a switch with SFP+ ports?
Yes. The original Cisco DS-SFP-FC4G-SW is a regular SFP form factor optic, while the EdgeOptic 10GBASE-SR replacement is SFP+. The two cages are mechanically distinct: an SFP+ optic does not fit in an SFP-only port. For Cisco MDS fabric switches that have been refreshed to SFP+ host ports, the EdgeOptic 10GBASE-SR SFP+ drops directly into the upgraded cage. For deployments still running legacy 4GFC line cards with SFP-only cages, the chassis or line card hardware needs to be migrated to SFP+ before the SR replacement can be used. Verify the host port cage type against the Cisco MDS line card documentation before substituting.
