GLC-SX-MM is a high performance SFP transceiver module that supports data rates up to 1.25Gbps over multi-mode fiber up to 550m. It uses an 850nm VCSEL laser transmitter and works with 50/125um or 62.5/125um multi-mode fiber. GLC-SX-MM is hot-swappable and compatible with Gigabit Ethernet ports to connect switches, firewalls, and wireless LAN controllers. It can also be used for fiber channel connections between servers and storage devices. GLC-SX-MM upgrades and replaces the older GBIC transceiver WS-G5484, and SFP+ transceivers further upgrade

1. Fine-detail information about GLC-SX-MM
About GLC-SX-MM
GLC-SX-MM SFP transceivers are high performance modules that support a
data-rate of 1.25Gbps and can transmit data up to 550m over multi-mode
fiber.GLC-SX-MM is 1000Base-SX SFP fiber optic transceiver for multimode
fiber and it works at 850nm wavelength, Cisco GLC-SX-MM SFP is
compatible with IEEE 802.3z and could reach 550 meter working distance via
50/125 multimode fiber, on 62.5/125 multimode fibers it could reach 220
meters. GLC SX MM SFP is hot swappable module that fit for Gigabit
Ethernet port or slot and link the port with the network, GLC SX MM is about
1.3 cm x 5.7 cm x 0.9 cm in dimension, and 75g in weight.

Applications of GLC-SX-MM
Gigabit Ethernet between switches, from switches to Wireless LAN
Controllers, between switches and firewalls.
Fiber Channel – Connecting servers to NAS or SAN devices.
GLC-SX-MM is the upgrade version of WS-G5484
GLC-LH-SM uses the 1310nm SMF which upto 10km distance but it usually
more expensive, the GLC-SX-MM SFP transceiver can treat as the upgrade
version of the GBIC transceiver WS-G5484. and the SFP+
transceiver SFP-10G-SR is called SFP plus transceiver which it is not only the
upgrade version of GLC-SX-MM but also develop the fiber optic network to a
new level with XENPAK transceiver, XFP transceiver, X2 transceiver.
