Fiberstore Compatible 1000BASE-LX/LH SFP modules

1000BASE-LX/LH was standardized six years after the initial gigabit fibre versions as part of the Ethernet in the First Mile task group. It is very similar to 1000BASE-LX, but achieves longer distances up to 10 km over a pair of single-mode fibre due to higher quality optics. The 1000BASE-LX/LH SFP module, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fibre-optic link spans of up to 10 km and up to 550 m on any multimode fibres. Duplex LC/PC connector.

Fiberstore 1000Base-LX/LH SFP module over single-mode fibre, which is a high performance and cost effective transceiver. It is designed to meet Gigabit Ethernet (1000Base) application. The transceiver consists two sections: the transmitter section consists of a high reliability 1310nm FP LD with monitor photo detector (MPD) in eye safety; the receiver section consists of a high-speed InGaAs PIN photodiode (PD) and trans-impedance preamplifier. The output of the PD drives the post-amplification, quantizing, and optical signal detection circuits. The receiver is built in the LOS monitoring function. For further information, please see SFP MSA and SFF-8472 standard.

Cisco Switch Controllers Accepted these SFP Modules

A distribution system port connects the controller to a neighbor switch and is used as the data path between these two devices. This paper talk about a few common methods on the models that have these options. Cisco 4402 controllers have two Gigabit Ethernet distribution system ports, each of which is capable of managing up to 48 access points (AP). Cisco 4404 controllers have four Gigabit Ethernet distribution system ports, each of which is capable of managing up to 48 APs per port. The 4404-25, 4404-50, and 4404-100 models allow a total of 25, 50, or 100 APs to join the controller. The Gigabit Ethernet ports on the 4402 and 4404 controllers accept these SX/LC/T SFP modules:

  • 1000BASE-SX SFP modules, which provide a 1000-Mbps wired connection to a network through an 850nm (SX) fibre-optic link using an LC physical connector
  • 1000BASE-LX/LH SFP modules, which provide a 1000-Mbps wired connection to a network through a 1300nm (LX/LH) fibre-optic link using an LC physical connector
  • 1000BASE-T SFP modules, which provide a 1000-Mbps wired connection to a network through a copper link using an RJ-45 physical connector

1000BASE-T SFP modules

The Cisco 5508 controllers have eight Gigabit Ethernet distribution system ports through which the controller can manage multiple APs. The 5508-12, 5508-25, 5508-50, 5508-100, and 5508-250 models allow for 12, 25, 50, 100, or 250 APs to join the controller. Cisco 5508 controllers have no restrictions on the number of APs per port. However, Cisco recommends using link aggregation (LAG) or configuring dynamic AP-Manager interfaces on each Gigabit Ethernet port to automatically balance the load. If more than 100 APs are connected to the 5500 series controller, make sure that more than one Gigabit Ethernet interface is connected to the upstream switch. The Gigabit Ethernet ports on the 5508 series controller, make sure that more than one Gigabit Ethernet interface is connected to the upstream switch. The Gigabit Ethernet ports on the 5508 controllers accept these SX/LC/T small-factor plug-in (SFP) modules:

  • 1000BASE-SX SFP modules, which provide a 1000-Mbps wired connection to a network through an 850nm (SX) fibre-optic link using an LC physical connector
  • 1000BASE-LX SFP modules, which provide a 1000-Mbps wired connection to a network through a 1300nm (LX/LH) fibre-optic link using an LC physical connector
  • 1000BASE-T SFP modules, which provide a 1000-Mbps wired connection to a network through a copper link using an RJ-45 physical connector

Cisco GLC-LH-SM SFP Transceiver Modules

SFP transceivers(Small form factor pluggable) is prefered to  easier to change and easier for maintenance rather than traditional modules and is expected to perform at data speeds of up to five gigabits per second (5 Gbps), and possibly higher.

SFP interfaces between communication devices like switches, routers and fibre optic cables, and performs conversions between optical and electrical signals. SFP transceivers support communications standards including synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), gigabit ethernet and fibre channel. They also allow the transport of fast Ethernet and gigabit Ethernet LAN packets over time-division-multiplexing-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks.

SFP Transceivers have a wide range of detachable interfaces to multimode/single-mode fibre optics, which allows users to select the appropriate transceiver according to the required optical range for the network. Signal transmitting rate of SFP modules range from 100Mbps up to 4Gbps or more, working distance of these SFP transceiver modules can be from 500 meters to 100 kilo meters, working wavelength of different SFP modules are typically 850nm, 1310nm and 1550nm, there are also CWDM type SFP transceivers available.
