100G CFP2 LR4 10km Optical Transceiver
Product Overview
The Apex 100G CFP2 LR4 module carries a 100GBASE-LR4 link to 10km over a single mode fiber pair. It uses the same four lane LAN-WDM design as the ER4 part, with the wavelengths multiplexed inside the module so the host sees a single 100G duplex LC interface.
10km is the standard reach for 100G between buildings on a campus, between two data halls, or between a transport shelf and a nearby aggregation site. LR4 is the most widely deployed 100G interface, so it is also the part that has to be available at short notice for replacements and spares.
The module is hot pluggable with a CAUI-4 electrical interface, supports DDM with per lane optical readings, and is coded for the platform you name. The standard 10km grade is held in stock for same day quoting, and the 40km ER4 version is available from the same line where the span is longer.

Applications
Campus and Data Hall 100G Links
Connects 100G ports between buildings or between halls on a single mode fiber pair inside the 10km reach.
Carrier Aggregation Sites
Provides the standard 100G client interface between transport equipment and an aggregation or exchange building.
100G Spares and Replacements
Keeps ageing transport and routing platforms running with the most widely used 100G interface, held in stock.
Compatibility
CFP2 LR4 modules are coded for the transport, routing or OTN platform you name and tested before shipment. Where a platform supports both CFP2 and QSFP28 cages, we normally recommend the QSFP28 part for cost and availability, and keep CFP2 for cards that only accept the larger package.

Frequently Asked Questions
What is the reach of a CFP2 LR4 module?
10km over standard single mode fiber, using four 25G lanes on the LAN-WDM grid multiplexed into one duplex LC interface.
Does CFP2 LR4 need forward error correction?
Yes. 100G LAN-WDM interfaces use RS(528,514) forward error correction, which the host line card enables as part of the 100G port configuration.
Can both ends use different vendors?
Mixing vendors on the same 100G link usually works when both parts follow 100GBASE-LR4 and the host is configured correctly, but for supported deployments we recommend matched coding and matched test reports at both ends.
Is CFP2 LR4 in stock?
Yes. The standard 10km grade is held in stock and quoted the same day, with ER4 and coherent CFP2 parts available from the same line.
