It supports dual<br \/>\ndata-rate of 1.25Gbps\/1.06Gbps and 20km transmission distance with 9\/125um single mode fiber. This 1.25G SFP LX<br \/>\ntransceiver module fully complies with the SFP Multi-Sourcing Agreement (MSA) and can be used on MSA compliant<br \/>\nSFP ports of optical networking equipment. The transmitter section uses a 1310nm FP laser that is a class 1 laser<br \/>\nproduct compliant according to International Safety Standard IEC 60825. The receiver section uses a high-speed PIN<br \/>\nphotodiode integrated with a trans-impedance preamplifier (TIA).<br \/>\nThere are three versions of the series 1.25Gb\/s SFP LX optical transceiver modules for different applications. The<br \/>\nStandard grade (0~70\u00baC) is for commonly commercial application, the Extended grade (-10~85\u00baC) is for Extended<br \/>\ntemperature application, and the Industrial grade (-40~85\u00baC) is made with robust and reliable components to meet the<br \/>\nneeds of Industrial Ethernet application under harsh environmental conditions.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>A<\/strong><strong>b<\/strong><strong>solute Maximum Ratings<\/strong><\/p>\n<p>&nbsp;<\/p>\n<table style=\"height: 262px;\"

It is very closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications. The standard SFP serial ID provides access to identification information that describes the transceiver\u2019s capabilities, standard interfaces, manufacturer, and other information.<\/p>\n<p>&nbsp;<\/p>\n<p>Additionally, Optcore 1.25Gb\/s SFP LX optical transceiver provide an optional enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as <strong>transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage<\/strong>.It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.<\/p>\n<p>&nbsp;<\/p>\n<p>The SFP MSA defines a 256-byte memory map in E2PROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The interface is identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement.<\/p>\n<p>&nbsp;<\/p>\n<p>The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver into those segments of the E2PROM that are not write-protected. The negative edge clocks data from the SFP transceiver module. The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially.<\/p>\n<p>&nbsp;<\/p>\n<p>Digital diagnostics for this 1.25G SFP LX optical transceiver is internally calibrated by default.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Features<br \/>\n\u25cf Support Up to 1.25Gb\/s data links<br \/>\n\u25cf Compliant with SFP MSA standard<br \/>\n\u25cf Compliant with IEEE 802.3z<br \/>\n\u25cf Hot pluggable SFP footprint<br \/>\n\u25cf 1310nm FP laser transmitter and PIN photo-detector<br \/>\n\u25cf Single 3.3V power supply<br \/>\n\u25cf Duplex LC connector<br \/>\n\u25cf Low power dissipation<br \/>\n\u25cf Metal enclosure provides lower EMI<br \/>\n\u25cf ROHS compliant and Lead Free<br \/>\n\u25cf Operating Temperature: Standard 0~70\u00baC\u00a0\u00a0\u00a0\u00a0 Extended -10~85\u00baC\u00a0\u00a0\u00a0 Industrial -40~85\u00baC<br \/>\n\u25cf Optional Digital Diagnostic Monitor Interface<\/p>\n<p><a href=\"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-content\/uploads\/2024\/02\/OSP1250-3120xxR_DS.pdf\"><strong>Data Sheet<\/strong><\/a><\/p>\n","protected":false},"featured_media":2059,"comment_status":"closed","ping_status":"closed","template":"","meta":{"content-type":""},"product_brand":[],"product_cat":[652,606],"product_tag":[1163,1160,1161,1162,1159],"class_list":{"0":"post-2058","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-1-25gb","7":"product_cat-transceivers","8":"product_tag-1-25gb-s-sfp-lx-optical-transceiver-module-single-mode-1310nm-20km-reach","9":"product_tag-module-single-mode-1310nm-20km-reach","10":"product_tag-osp1250-3120xxr-1-25gb-s-sfp","11":"product_tag-osp1250-3120xxr-1-25gb-s-sfp-20km-reach","12":"product_tag-osp1250-3120xxr-1-25gb-s-sfp-lx-optical-transceiver-module-single-mode-1310nm-20km-reach","14":"first","15":"instock","16":"taxable","17":"shipping-taxable","18":"purchasable","19":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/product\/2058","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/comments?post=2058"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/media\/2059"}],"wp:attachment":[{"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/media?parent=2058"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/product_brand?post=2058"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/product_cat?post=2058"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/fiberwarehouse.co.za\/optic-fiber\/wp-json\/wp\/v2\/product_tag?post=2058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
