Built to maximize bandwidth, scalability, and reliability, this CFP2 transceiver delivers four parallel 25 Gbps lanes to achieve a full 100 Gbps data rate over long‑haul links. With a designated ER reach of 40 kilometers on single‑mode fiber (SMF), it is purposefully designed for backhaul, inter‑data center, and metro applications where high capacity, low latency, and robust performance are essential. The compact CFP2 form factor enables dense, high‑velocity deployments in modern network architectures, making it an ideal choice for hyperscale data centers, cloud providers, and telecommunications operators seeking to optimize fiber utilization and rack space without compromising performance. Accortec’s ER4 solution also emphasizes interoperability, enabling seamless integration with a wide range of 100G switches, routers, and optical transport networks that support CFP2 modules and CAUI‑4 interfaces. Whether upgrading an existing 10G/40G backbone or scaling a new 100G data plane, this transceiver provides a dependable, future‑proof option for long‑reach, high‑density networks.

• High-speed ER4 architecture in a compact CFP2 form factor - This module consolidates four 25 Gbps lanes into a single 100 Gbps transceiver, enabling data centers and service providers to scale bandwidth without expanding rack space. The four‑lane design preserves efficiency while delivering the reliability and performance required for backbone interconnects, campus backbones, and inter‑data center links. Ideal for upgrading 40G/100G footprints, the Accortec ER4 CFP2 supports aggressive densification strategies while maintaining compatibility with standard 10G/40G upgrade paths.
• 40 km reach on single‑mode fiber for long‑haul reliability - Engineered for ER (Extended Reach) operation, this transceiver maintains strong signal integrity across 40 kilometers of SMF. It is optimized for metropolitan networks, data center interconnects, and service provider deployments where mid‑to‑long‑haul connectivity is essential. The ER4 reach helps minimize the need for repeaters or opaque routing while preserving low error rates and high optical signal quality over the link.
• Parallel fiber interface with MPO/MTP connector for dense cabling - The optical interface uses a parallel multi‑fiber connection (MPO/MTP) to support the four 25 Gbps channels in parallel. This arrangement enables high‑density fiber layouts, simplified cabling upgrades, and streamlined interconnects to optical distribution frames (ODFs) and high‑capacity switches. The MPO/MTP approach reduces connector count and simplifies fiber management in crowded data center racks and telecom rooms.
• CAUI‑4 electrical interface for straightforward integration - On the host side, the transceiver communicates using the standard CAUI‑4 electrical interface, facilitating plug‑and‑play compatibility with a broad ecosystem of 100G Ethernet switches and routers. This common electrical interface minimizes integration risk, simplifies cabling configurations, and supports efficient migration scenarios from 40G/100G architectures to 100G ER4 deployments.
• Reliability, efficiency, and enterprise‑grade design - Accortec’s 100 Gbps ER4 CFP2 transceiver emphasizes robust performance in commercial environments. Expect dependable operation under 24/7 workloads, optimized power usage for dense deployments, and adherence to industry standards that help reduce total cost of ownership. The module is engineered for interoperability across fiber networks, with QoS‑aware performance that supports latency‑sensitive applications, cloud services, and large‑scale data processing.

How to install Accortec 100 Gbps ER4 (40 Km) CFP2 Optical Transceiver

• Step 1: Confirm compatibility and prerequisites - Verify that your switches or routers support CFP2 ER4 optics and CAUI‑4 electrical interfaces. Check the device’s interoperability matrix and confirm firmware and line card compatibility before installation.
• Step 2: Prepare the equipment - Power down the device if hot‑swap is not supported, or follow your vendor’s hot‑swap procedure. Ground yourself to prevent electrostatic discharge and handle the module with care to avoid damage to connectors and latch mechanisms.
• Step 3: Install the transceiver - Align the CFP2 module with the slot in the line card or fabric interconnect, then slide it in firmly until the latch engages. Do not force the module, and ensure that the mechanical guides align with the housing for proper seating.
• Step 4: Connect optical fiber - Attach the MPO/MTP 12‑fiber fiber harness to the module’s optical interface, ensuring correct polarity and fiber orientation. Use clean, fiber‑appropriate tools and perform a basic inspection for any dust or debris that could affect signal quality.
• Step 5: Attach host electrical connections - Connect the CAUI‑4 electrical interface to the corresponding ports on the switch or router, following the device’s breakout or port‑mapping guidelines. Ensure cable discipline and routing to avoid bending or stress on the connectors.
• Step 6: Power up and verify - Power on the equipment (or confirm hot‑swap status if supported). Check link status indicators, run baseline tests, and verify the 100 Gbps link is established. Monitor optical power levels and error counters to confirm a healthy ER4 link across the 40 km path.
• Step 7: Configure and validate - Apply any necessary interface configurations (e.g., lane mapping, QoS policies, and routing considerations) and perform throughput tests or traffic emulation to ensure the 100 Gbps ER4 link meets performance targets in your network topology.
