DS-SFP-FC16G-LW Description
The DS-SFP-FC16G-LW is a Cisco MDS 9000 Series 16-Gbps Fibre Channel longwave SFP+ transceiver for single-mode SAN links between buildings or data center halls. The transceiver autosenses 4, 8 and 16 Gbps on an LC interface, transmits at 1310 nm and reaches 10 km over single-mode fiber at 0 to 70 degrees C. On the MDS 9124V, 9148V and 9396V the optic is supported only from release 9.3(x), not on 9.2(x).

Application Scenarios
A storage team joins two MDS 9000 Series switches in separate campus buildings over duplex LC single-mode fiber. The transceiver carries 4, 8 or 16 Gbps Fibre Channel across spans of up to 10 km.
An older 8G storage array and a newer 16G MDS port can share one long single-mode run. The transceiver autosenses 4, 8 and 16 Gbps, so the fabric does not need a separate optic per speed.

DS-SFP-FC16G-LW is the 1310 nm single-mode model of this group, rated for 10 km, while DS-SFP-FC16G-SW runs 850 nm over multimode fiber and reaches only 125 m at 16 Gbps on OM4 or OM5, so a multimode patch plant needs DS-SFP-FC16G-SW instead. Both autosense 4/8/16 Gbps on LC connectors. A single-mode route longer than 10 km needs DS-SFP-FC16GELW, which is documented for 25 km and transmits at -2.0 to 5.0 dBm against -5.0 to 2.0 dBm on DS-SFP-FC16G-LW. Cisco lists DS-SFP-FC16G-LW on MDS 9124V, 9148V and 9396V only from release 9.3(x), not on 9.2(x).
Ordering Checklist
- Host support: Confirm the host is an MDS 9132T, 9148T, 9396T, 9220i, 9250i, 9148S or 9396S switch, or a DS-X9334-K9, DS-X9448-768K9 or DS-X9648-1536K9 module. This optic is listed only for specific MDS hosts, so a generic SFP+ port elsewhere is not covered.
- Fiber and connector: Use dual LC patch cords on 9 micron single-mode fiber. The longwave optic cannot link over a multimode plant.
- Spare PID: Order DS-SFP-FC16G-LW= when the order is for a spare. Each spare is listed under its own PID with an equals sign.
