New Transceivers/Receivers Take Aim At OC-3 To OC-192 Apps

Optical networking systems spanning operational speeds of from 155 Mb/s (OC-3) to 10 Gb/s (OC-192) represent the spectrum of applications for a series of products that include pluggable transceivers, enhanced Netlight transceivers offering an extended temperature range, a high-performing 10-Gb/s positive-intrinsic-negative (PIN) receiver, and enhanced 2.5-Gb/s 1R/2R/3R receivers. Used for sending and receiving light signals across fiber-optic networks, the new NLP small-form-factor transceivers are designed to be plugged into rather then soldered onto boards, enabling the transceivers to be easily swapped to accommodate different system speed or distance requirements. The pluggable transceivers come in OC-3 (155-Mb/s), OC-12 (622-Mb/s), OC-48 (2.5-Gb/s), Gigabit Ethernet (1.25-Gb/s) and Fibre Channel (1.0622-Gb/s) versions, with the OC-3 and OC-12 transceivers handling distances of up to 15 km, OC-48 devices rated for use of up to 2 km, and the gigabit devices designed for applications up to 5 km over single-mode fibers. The new, 10-Gb/s PIN receiver is a small-form-factor device that boasts of a sensitivity of -18 dB and overload spec of +1 dB. Manufactured using coplanar waveguide technology, the R192P receiver has a RF noise spec significantly lower than that offered by shielded coax receivers. And it is also offered without a mounting flange to further reduce size.The manufacturer has also developed wide temperature (-40¡C to 85¡C) versions of its OC-3 and OC-12 Netlight transceivers for use, for example, in non-controlled telecomm carrier environments and enhanced versions of its 2.5-Gb/s 1R/2R/3R receivers for intermediate- and short-reach applicationsÑthe enhancements for the receivers include extended temperature range and single power supply devices.
