The TC3210 10/100Base-T-to-fiber Ethernet media converter handles high-temperatures (-40° to +80°C) as well as distances up to 100 km and features power redundancy and two-way optional "single" fiber capability available on singlemode fiber-optic cable. It is auto-negotiating for 10- and 100-Mbit/sec Ethernet links to convert 10/100-Mbit/sec Ethernet unshielded twisted-pair to singlemode (1300/1500-nm) or multimode (1300-nm) fiber optics. Transparent to the network, the converter operates efficiently even during high-demand traffic loads, according to the company. Power is 12 VDC, or optionally, 24 VDC, 48 VDC, or 115/230 VAC with an external power cube. Dry contact alarms are provided for connection to remote network management systems. Local loopback, five LED indicators, and an uplink/downlink slide switch are provided to aid in installation and troubleshooting. The converter is available in standalone or rackmount.

The 10-Gbit/sec MSA (multisource agreement) line of optical transponders was designed with a very small footprint (75×55×12 mm), enabling easy integration with large-capacity optical transmission systems and high-speed IP routers and reducing the development period and equipment size needed for large-capacity systems. The OD-J8665, OD-J8666, OD-J8791, OD-J8792, OD-J8793 and OD-J8794 transponders require 4-6 W of power to operate; support bit rates of 9.95, 10.3, and 10.7 Gbits/sec as well as distances of SR-2 (25 km) and IR-2 (40 km); and support 300-pin MSA specifications proposed by 11 leading optical module vendors. The transponders also support SONET, SDH, and 10-Gbit/sec Ethernet applications; operate in temperatures of -5° to +70°C; and feature cooled EML and pin-PD optical modules, a built-in 16:1 multiplexer and 1:16 demultiplexer, and a 6xx.xx-Mbit/sec LVDS electrical interface.

The ParaLink-P pluggable 12-channel parallel module for high-speed, high-density optical data transfer applications like optical crossconnects and terabit routers plug into a 10×10 ball-grid-array socket previously mounted on the motherboard to allow for more flexible final assembly, test, and repair. It comes in separate transmitter and receiver modules. The transmitter is based on a VCSEL array with monitor feedback, providing constant optical output over the transmitter's life, and the receiver has a highly sensitive GaAs PIN photodetector array. ParaLink operates up to 2.7 Gbits/sec per channel for total data throughput up to 32.4 Gbits/sec over 200 m on 62.5-mm core multimode fiber, provides low power consumption, is compact (54×18 mm), and has a low profile (8.4 mm). The optical interface is an MT-based MPO/MTP receptacle for easy connection to standard 12-fiber-based ribbon cable.

The CCT2001 continuity tester provides field technicians with a high-intensity green LED light source that transmits light instantly and accurately down the fiber. Compatible with singlemode and multimode fiber, it can test all types of connectors, including ST, FC, SC, LC, and MT-RJ, and can reach a multimode-fiber test distance up to 2 km. The tester comes with1.25-mm, 2.5-mm, and MT-RJ-style adapters, LR44 or PX76A batteries, and a key ring. Adapters are interchangeable and the lamp bulb is replaceable.
