Cisco 100G ER4-Lite QSFP28 Transceiver Module, Single-Mode LC

Overview
Long-haul at 100GbE is the purpose of the Cisco 100G ER4-Lite QSFP28 Transceiver Module, part number QSFP-100G-ER4L-S. It uses a duplex LC connector over single-mode fiber, with wavelengths from 1295 to 1309 nm.
The reach is 40 km with host FEC and 30 km without it. That distinction is practical: the longer figure needs forward error correction enabled on the host port, so confirm that your switch supports it before you plan a 40 km span. Without FEC, the usable distance is 30 km.
Such distances connect separate sites in a metro area or large campus, without extra transport equipment. The module is a QSFP28 with one port.
Because optical budget decides success on long links, check fiber loss, connectors and splices on the actual route, and confirm both ends use compatible modules and settings.
The QSFP-100G-ER4L-S is offered in new, refurbished and used condition. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send us your quantity, the span length and the host platform with your request.
