QSFP-40G-ER4
40G QSFP+ ER4 60KM LC Optical Transceiver

Product Overview EQP294X-60D(I) is designed for 60km optical communication applications. Optical transceiver integrates the transmit and receive path onto one module. On the transmit side, four lanes of serial data streams are recovered, retimed and passed on to four laser drivers, which control four electric-absorption modulated lasers (Lan-WDM) with 1296, 1300, 1305, and 1309 nm center wavelengths. The optical signals are then multiplexed into a single-mode fiber through an industry-standard LC connector. On the receive side, four lanes of optical data streams are optically De multiplexed by an integrated optical De multiplexer. And passed on to an output driver, the receiver adopts APD. This module features a hot-pluggable electrical interface, low power consumption, and 2-wire serial interface. PRODUCT FEATURES Transmission data rate up to 11.2Gbps per channel QSFP+ MSA compliant Compliant to IEEE 802.3ba specification for 40GBASE-ER4 links 4 CWDM un-cooled DFB lasers, using ITU G.694.2 wavelength grid at 1271, 1291, 1311 and 1331nm High Sensitivity APD-TIA with optical DEMUX Up to 60km reach over standard single mode fiber Hot pluggable electrical interface Operating case temperature 0°C to +70°C 3.3V power supply RoHS 6 compliant(lead free) 40G LR4 10KM 40G LR4 10KM (COB) 40G ER4 40KM 40G eER4 60KM 40G  ZR4 80KM 40G 40G 40G 40G 40G 1271nm, 1291nm, 1311nm, 1331nm 1271nm, 1291nm, 1311nm, 1331nm 1271nm, 1291nm, 1311nm, 1331nm 1296nm, 1300nm, 1305nm, 1309nm 1296nm, 1300nm, 1305nm, 1309nm 10KM 10KM 40KM 60KM 80KM LC LC LC LC LC SM SM SM SM SM DDM DDM DDM DDM DDM COM: 0°C ~70°C IND: -40°C ~85°C COM: 0°C ~70°C COM: 0°C ~70°C IND: -20°C ~85°C COM: 0°C ~70°C IND: -40°C ~85°C COM: 0°C ~70°C IND: -40°C ~85°C FAQ: Q1: What is a 40G QSFP Optical Module?‌ A1: A 40G QSFP (Quad Small Form-factor Pluggable) module is a hot-swappable transceiver that supports 40Gbps data transmission.
