GLC-SX-MMD Overview

Cisco GLC SX MMD – Redefining the short range data connectivity

Cisco GLC SX MMD is SFP transceiver module compatible with multimode fiber networks. This transceiver follows 1000BASE-SX Ethernet standard of cabling and is ideal interconnectivity solutions for linking IEE approved ports, routers and others to optical fiber networks. The Cisco GLC SX MMD transceivers are provided with LC/PC connector interface for extending optical fiber connectivity to a wide variety of networking equipment provided with these power-efficient interfaces.

Operational requirements of Cisco GLC SX MMD

This 1000BASE-SX SFP transceiver from Cisco transmits data over multi-mode fiber, thus, is an ideal transceiver module for short range networks spanning over a distance of 550m. The wavelength at the cabling end should be 850nm to achieve the desired output. Since it is understandable that the transceivers work as connecting link between electric circuitry of the hardware and optical fiber network, the main challenge is to eliminate the insertion and return loss during transmission. Cisco GLC SX MMD is a nice solution to this problem. It does not require more than +3.3V of power for functioning and the insertion loss achieved is bare minimum. Thus, this Cisco transceiver module is proving its worth in all modern day networking infrastructure. Cisco GLC SX MMD transceiver module is tried on and tested for compatibility with a wide range of hardware and networking equipment that comply with industrial standards. The makers need to find a practical connectivity solution that can withstand extreme weather conditions; and so, this high performance transceiver delivers its best at the commercial temperature range of 0-70 degree Celsius. This transceiver is compatible with 1GbE applications and networking solutions, and is designed in accordance with the specifications laid out in RoHS, IEC, MSA and other industry set quality standards. It delivers 1Gbps of data speed and is ideal for short range connections. The transceiver is provided with LC/PC connectors. Patch cord that can be used across Cisco GLC SX MMD feature UPC and PC endfaces; APC endface is not compatible with multimode fiber network. Cisco GLC SX MMD can deliver data connectivity to a range of 220m on FDDI-grade multi-mode fiber of 62.5 micron density, while the reach can be extended to 550m using an ordinary multi-mode fiber.

How Cisco GLC SX MM and Cisco GLS SX MMD are different

Many a times it is asked how Cisco GLC SX MM transceiver is different from Cisco SX MMD. Well, there are a number of similarities between the two. The latter is also featuring a duplex LC interference, complements OM2 MMF and delivers connectivity up to a range of 550 meters. It is MSA compliant too. The only additional feature in MMD type is the presence of DDM function and data connectivity at the rate of 1.25 Gbps. DDM is a smart feature that brings in sort of intelligence to the functioning of GLC SX transceiver from Cisco. The DDM performs the function of monitoring as well as warning. It sends warning alerts whenever anything in the networking infrastructure is not in line with the factory specifications of the transceiver. Thus, this function offers ample opportunity to the users for avoiding abuse, correcting faults and extracting the best performance from the transceiver module.

Advantages of Cisco GLC SX MMD

The demanding nature of the networking infrastructure of present times requires connectivity solutions that perform better than copper cables. Cisco GLC SX MMD is one such connectivity solution that has improved the scenario. Organizations consider this transceiver as the backbone of the communication frame-work that they need to develop and maintain for keeping up with the operational requirements. This transceiver is ideal option to consider for LAN and other networks. It offers greater bandwidth than a conventional copper cable and thus, makes it possible to upgrade the networks to something speedier as well as long-lasting. The hot-swappable nature of Cisco GLC SX MMD delivers better cost-efficiency and the upgradation process is reduced to simple plug-and-play model, thereby reducing the effort and eliminating the need to bring the whole system to a standstill.

Limitations of Cisco GLC SX MMD

Cisco GLC SX MMD transceiver can deliver its best only when the port matches the wavelength specifications mentioned on the either end of the cable. And the user must select the cable length as per the set norms related to functionality. The only restriction is that each port must match the wavelength specifications on the other end of the cable and that the cable must not exceed the stipulated cable length for reliable communications.
